1. 1. When a museum label reads acquired 1897, the date does a quiet kind of work. It fixes attention on the moment of transfer and away from everything that made the transfer possible: the gunboat in the harbor, the treaty signed under duress, the market that had already priced the object before it left the shrine. Curators who defend such labels say they record only what can be documented. But a record that documents the buyer and not the taking is not neutral. It is a decision about which part of the story deserves a date. Which of the following best states the main idea of the passage?

   • A. Museums should return the objects they acquired during colonial rule.
   • B. Curators knowingly falsify the provenance records of objects in their collections.
   • C. An acquisition date presents a selective account of an object's history as though it were a neutral one.
   • D. Reliable documentation is impossible for objects taken before the twentieth century.
   Mostrar resposta e explicação

   Resposta: C. An acquisition date presents a selective account of an object's history as though it were a neutral one.

   This is a foundations of comprehension question, main idea. The last two sentences decide it: the record is not neutral, and the date is a choice about which part of the story counts. The return of objects is never mentioned, so that choice is out of scope. Knowing falsification is too extreme, since the author says the labels record what can be documented and objects to what gets left out, not to lying. The last choice states an impossibility the passage never claims.

2. 2. Every generation of critics announces that the last one asked the wrong questions, and every generation is partly right. The formalists were correct that a poem is made of words and not of the poet's biography. Their successors were correct that words do not sit still. What neither camp admits is how much of the quarrel is procedural, a matter of which evidence a critic is permitted to bring into the room. Read the manifestos side by side and the shared assumptions outnumber the disputed ones, though you would never guess that from the footnotes. The author's attitude toward these critical quarrels is best described as:

   • A. Sharply contemptuous of both camps
   • B. Neutral and purely descriptive
   • C. Admiring of the advances each generation made
   • D. Wry and unimpressed by the scale of the disagreement
   Mostrar resposta e explicação

   Resposta: D. Wry and unimpressed by the scale of the disagreement

   This is a foundations of comprehension question about tone. The closing clause, that you would never guess it from the footnotes, is dry rather than angry, and the author grants each camp a real point, so contempt is too extreme. Purely descriptive misses the evaluation running through the whole passage. Admiring is half right, since the author does credit both sides, but the point of the passage is that the fight is smaller than it looks.

3. 3. Complete the sentence.

   Oral historians once treated memory as a flawed substitute for the archive, valuable only where documents had gone missing. The newer view treats forgetting itself as evidence: what a community declines to repeat marks the shape of an injury as clearly as what it chooses to record. On this reading the interview is not a _____ source but a different kind of source, one that reports on the present at least as much as on the past.

   Opções para a lacuna 1: primary, written, deficient, contemporary

   Mostrar resposta e explicação

   Resposta: deficient

   This is a foundations of comprehension question about the meaning of a word in context. The first sentence sets up the old view, memory as a flawed substitute, and the last sentence rejects it with a contrast between quality and kind: not worse, just different. Only deficient carries that judgment. Primary, written and contemporary are all classifications rather than criticisms, so none of them is the thing the newer view is refusing.

4. 4. Utilitarians hold that an act is right if it produces the greatest total well-being. Critics answer with the transplant case: a surgeon could save five patients by killing one healthy visitor, and the arithmetic approves. Almost nobody accepts that conclusion. Defenders reply that a world in which surgeons behave this way would soon have no patients willing to walk into a hospital, so the rule forbidding the killing maximizes well-being after all. The reply is clever. It also concedes the critics' real point, which is that the arithmetic alone was never doing the moral work. The second paragraph functions primarily to:

   • A. Introduce a fresh objection that the first paragraph had not raised
   • B. Supply historical background for the transplant case
   • C. Restate the first paragraph in more technical language
   • D. Present a defense of the theory and then turn that defense against it
   Mostrar resposta e explicação

   Resposta: D. Present a defense of the theory and then turn that defense against it

   This is a reasoning within the text question about the function of a paragraph. The paragraph gives the defenders their answer and then says it concedes the critics' point, so it does two jobs and the second one is the author's. No new objection appears, since the objection is still the transplant case from paragraph one. There is no history in the passage at all, and nothing is merely restated, because the paragraph moves the argument forward.

5. 5. The claim that printing caused the Reformation rests on a tidy sequence: presses spread, pamphlets multiplied, doctrine changed. Yet the presses were busiest in cities that were already arguing about the church, and the same technology in Spain produced almost no reformist literature at all. The correlation is real. The causal arrow is not obvious. A technology does not choose its own uses, and the historian who forgets that will find the printing press explaining whatever the century happened to do. The author's argument depends on which of the following assumptions? Select all that apply.

   Marque todas as opções corretas.

   • A. A case in which the technology spread without producing the outcome is relevant to judging the causal claim.
   • B. A correlation between two developments is not by itself enough to show that one caused the other.
   • C. The printing press had no effect at all on religious change in Europe.
   • D. Conditions already present in a place can shape what a new technology gets used for.
   • E. Spanish printers were less technically skilled than their German counterparts.
   Mostrar resposta e explicação

   Resposta: A. A case in which the technology spread without producing the outcome is relevant to judging the causal claim., B. A correlation between two developments is not by itself enough to show that one caused the other., D. Conditions already present in a place can shape what a new technology gets used for.

   This is a reasoning within the text question about unstated assumptions. The Spain example only counts as evidence if a case without the outcome bears on the causal claim, and the whole passage turns on correlation not settling causation. The point that presses were busiest where the argument was already under way assumes local conditions steer use. The no effect at all choice is too extreme, since the author says the arrow is not obvious rather than absent, and skill in Spain is a detail the passage never raises.

6. 6. Defenders of the standard concert program argue that audiences want the familiar, and they point to the box office: halls fill for Beethoven and empty for almost anything written after 1950. The figure is accurate. It is also a poor test of the claim, because the programming decides in advance which unfamiliar works get a hearing at all, and then books them late in the season, in smaller rooms, without the marketing the warhorses receive. A preference measured only under the conditions that produce it explains very little. The author's main objection to the box office evidence is that:

   • A. The conditions under which the preference is measured are set by the very practice the evidence is meant to justify.
   • B. The ticket figures the defenders cite are not accurate.
   • C. Audiences in fact prefer new music to the older repertoire.
   • D. Concert halls built after 1950 are too small to hold large audiences.
   Mostrar resposta e explicação

   Resposta: A. The conditions under which the preference is measured are set by the very practice the evidence is meant to justify.

   This is a reasoning within the text question about the strength of support. The decisive sentence is the last one: the measurement is contaminated by the practice it is supposed to defend. The accuracy choice is directly contradicted, since the author concedes the figure is accurate. The claim that audiences prefer new music is stronger than anything the author says, and the small rooms detail is about scheduling of new works, not about when the halls were built.

7. 7. Translators speak of a text's grain, the resistance it offers to being carried across. A sentence with little grain slides into the new language and leaves no mark, and the reader forgets there was ever another version. High grain does the opposite. Idioms sit awkwardly, rhythms refuse to line up, and the translator has to decide whether to sand the surface smooth or to leave the roughness visible as a sign that the reader is a guest in someone else's house. In the passage, to sand the surface smooth most nearly means to:

   • A. Shorten the text so that it reads more quickly
   • B. Choose a more literal, word for word rendering
   • C. Make the translation read as though it had been written in the new language
   • D. Correct factual errors that appear in the original
   Mostrar resposta e explicação

   Resposta: C. Make the translation read as though it had been written in the new language

   This is a foundations of comprehension question about the meaning of a phrase in context. The alternative given in the same sentence, leaving the roughness visible so the reader feels foreign, fixes the meaning of the other option by contrast. Word for word is the opposite move, since literalism is what makes idioms sit awkwardly. Shortening and correcting errors are both true things translators sometimes do, but neither is what this sentence sets against visible roughness.

8. 8. Complete the sentence.

   Ethnographers who spend years in one village often report a discovery that embarrasses their training: the informants have theories too. They explain their own kinship rules, and the explanations are neither naive nor identical to the anthropologist's. Treating those accounts as raw data to be interpreted, rather than as _____ to be argued with, quietly reserves the work of thinking for the visitor. The fieldworker's authority then rests less on evidence than on _____.

   Opções para a lacuna 1: claims, rituals, errors, artifacts

   Opções para a lacuna 2: fluency, position, patience

   Mostrar resposta e explicação

   Resposta: claims, position

   This is a reasoning within the text question, since both blanks turn on how the author's argument is built. The contrast is between raw data, which you interpret, and something you can disagree with, and only claims can be argued with. The second blank follows from reserving the thinking for the visitor: if the informants' theories are ruled out in advance, what is left holding up the authority is who the fieldworker is rather than what the evidence shows.

9. 9. Cities preserve buildings for two different reasons that are often confused. One is aesthetic: the facade is worth looking at, and losing it would make the street poorer. The other is evidentiary: the building is the only surviving record of how a group of people lived, and no drawing or photograph replaces standing inside it. The second reason can protect an ugly building. It can also fail to protect a beautiful one, if a dozen near identical examples survive elsewhere in better condition. Based on the author's second reason, preservation would be most strongly justified for which of the following?

   • A. A handsome nineteenth century bank facade of a type found in many cities
   • B. A modern office tower that architects admire and photographers visit often
   • C. A ruined chapel already recorded in a complete set of measured drawings
   • D. A plain, poorly built shed that is the last standing example of a migrant labor camp
   Mostrar resposta e explicação

   Resposta: D. A plain, poorly built shed that is the last standing example of a migrant labor camp

   This is a reasoning beyond the text question, applying the author's distinction to new cases. The evidentiary reason turns on being the only surviving record, which the shed is and the common bank facade is not. The office tower is defended by the aesthetic reason, which the question does not ask about. The chapel is the case the author explicitly weakens, since full documentation is what the evidentiary reason cares about.

10. 10. The great man account of scientific change survives because it is easy to narrate. A single mind sees what everyone else missed, and the textbook gets a chapter title. Against it stands the pattern of simultaneous discovery: calculus, natural selection, the telephone, each arriving from more than one direction within a few years. If the problem, the instruments and the shared literature were ripe, the argument runs, some competent person was going to solve it, and the name attached is an accident of the calendar. Which finding, if true, would most weaken the argument made against the great man account?

    • A. Several celebrated cases of simultaneous discovery turn out to be separated by more than a decade and to differ substantially in content.
    • B. Many important discoveries were made by research teams rather than by individuals.
    • C. Textbooks devote more space to the biography of scientists than to their methods.
    • D. Scientific instruments improved unusually quickly during the nineteenth century.
    Mostrar resposta e explicação

    Resposta: A. Several celebrated cases of simultaneous discovery turn out to be separated by more than a decade and to differ substantially in content.

    This is a reasoning beyond the text question of the weaken type. The case against the great man account rests entirely on simultaneous discovery, so removing the simultaneity removes the evidence. Teams instead of individuals cuts against the lone genius, so it strengthens the same side. The textbook choice is about how history gets written, not about how discovery happens, and faster instruments support the ripeness claim the author is defending.

11. 11. Museums report record attendance and conclude that public interest in art is rising. Attendance counts admissions, though, and not interest. A traveling blockbuster, a free evening, a cruise ship in the harbor and a good lobby cafe all raise the number without anyone looking at a painting a moment longer. If the claim is about interest, the evidence has to survive the removal of every reason to walk into a museum that is not the art. By the standard the author sets, which findings would strengthen the museums' conclusion? Select all that apply.

    Marque todas as opções corretas.

    • A. Attendance rose in years with no blockbuster exhibition and no change in admission pricing.
    • B. The average time visitors spent in front of individual works rose along with attendance.
    • C. Museum cafes and gift shops reported higher revenue per visitor.
    • D. Admissions grew fastest in the cities that had opened new cruise terminals.
    • E. Membership renewals by residents of the museums' own cities rose over the same period.
    Mostrar resposta e explicação

    Resposta: A. Attendance rose in years with no blockbuster exhibition and no change in admission pricing., B. The average time visitors spent in front of individual works rose along with attendance., E. Membership renewals by residents of the museums' own cities rose over the same period.

    This is a reasoning beyond the text question about new evidence. The author's test is whether the rise survives once the non-art reasons are stripped out, so growth without a blockbuster or a price change, longer looking, and repeat commitment from locals all pass it. Higher spending in the cafe is the author's own example of a confounding attraction, and growth concentrated near cruise terminals is the tourism explanation rather than the interest one.

12. 12. Historians of the plague once wrote as though the mortality figures spoke for themselves. A third of a population dies, labor grows scarce, wages rise, serfdom weakens. The chain looks mechanical. But wages rose in England and did not rise across much of eastern Europe, where landlords met the same shortage by binding peasants more tightly to the land. Demography set the problem. It did not write the answer. What decided the outcome was who already held the power to respond, and that varied by region. The two short sentences, demography set the problem and it did not write the answer, serve mainly to:

    • A. Concede that the mortality figures are unreliable
    • B. State the general principle that the eastern European contrast is offered to support
    • C. Introduce a new topic that the passage then abandons
    • D. Summarize the mechanical chain described in the opening sentences
    Mostrar resposta e explicação

    Resposta: B. State the general principle that the eastern European contrast is offered to support

    This is a reasoning within the text question about the function of a sentence. The England and eastern Europe contrast is the evidence, and these two sentences are the lesson drawn from it, which the final sentence then spells out. The author never questions the figures themselves, only what follows from them. Nothing is abandoned, and the sentences reject the mechanical chain rather than summarizing it.

13. 13. Complete the sentence.

    Critics of the term folk art point out that it names a position rather than a style. The objects it gathers have almost nothing in common with one another, and everything in common in how they arrived at the museum: made outside the academies, collected by outsiders, exhibited without the maker's own account of the work. The category is therefore best read as a record of _____ rather than as a description of what the objects are.

    Opções para a lacuna 1: technique, geography, reception, chronology

    Mostrar resposta e explicação

    Resposta: reception

    This is a reasoning within the text question, since the blank has to match the argument the paragraph just made. Every shared feature the author lists is about how the objects were found, collected and displayed, which is reception rather than anything in the objects. Technique is ruled out by the sentence saying the objects have nothing in common with one another, and neither geography nor chronology appears in the list at all.

14. 14. Public apologies for historical wrongs are often dismissed as cheap, on the grounds that the speaker risks nothing and the dead gain nothing. The objection assumes that the audience is the dead. It is not. An apology issued by a state is a statement about what that state will now count as a wrong, made in front of the people who have to live under its judgments. Whether it is cheap depends on what it commits the speaker to afterward, and that is a question about the future rather than the past. The author's primary purpose is to:

    • A. Show that state apologies reliably lead to concrete reparations
    • B. Argue that historical wrongs cannot fairly be judged by present standards
    • C. Reject a common objection by showing that it misidentifies who is being addressed
    • D. Describe the wording that official apologies typically use
    Mostrar resposta e explicação

    Resposta: C. Reject a common objection by showing that it misidentifies who is being addressed

    This is a foundations of comprehension question about the author's purpose. The structure gives it away: an objection is stated, then the assumption inside it is named and denied, then the real audience is identified. Reliably leading to reparations is far stronger than the passage, which says only that the answer depends on later commitments. Judging the past by present standards is a different debate, and no actual wording is described.

15. 15. A canon is not a list of the best books. It is a list of the books a culture has agreed to keep arguing about. That is why a work can enter the canon by being attacked, and why a novel everyone admires and nobody rereads slips quietly out of it. The test is not praise. The test is continued use: does anyone still have to answer this book in order to say what they think? By the author's test, which of the following would count as evidence that a work belongs to the canon? Select all that apply.

    Marque todas as opções corretas.

    • A. Scholars publish sustained refutations of the book decades after it first appeared.
    • B. The book won the most prestigious literary prize of its year.
    • C. New writers structure their own books as replies to it.
    • D. The book outsold every other novel of its decade.
    • E. Critics who dislike the book still assign it so that they can argue with it.
    Mostrar resposta e explicação

    Resposta: A. Scholars publish sustained refutations of the book decades after it first appeared., C. New writers structure their own books as replies to it., E. Critics who dislike the book still assign it so that they can argue with it.

    This is a reasoning beyond the text question, applying a stated criterion to new cases. The author's test is continued use, and refutation, imitation in the form of reply, and hostile teaching are all cases of people having to answer the book. A prize and high sales are both forms of praise or popularity at a single moment, and the passage separates those from the test on purpose, since a book everyone admires can still drop out.

O que a seção CARS do MCAT realmente cobra de você

O CARS é a seção do MCAT que não testa ciência nenhuma. Você recebe 9 textos e 53 questões em 90 minutos, o que dá mais ou menos dez minutos por texto, contando as questões. Os textos têm várias centenas de palavras cada e vêm das humanidades e das ciências sociais: filosofia, ética, história, crítica literária, estudos culturais, história da arte e música. Tudo o que é preciso para responder está dentro do texto. Se uma questão parece exigir um fato de alguma das suas aulas, isso é sinal de que você importou algo que o texto nunca disse. Como as outras seções, o CARS é pontuado de 118 a 132, e as notas das quatro seções somam um total entre 472 e 528. Os detalhes de formato são atualizados, então trate o roteiro publicado pela própria AAMC como a autoridade e confira antes de confiar em qualquer número de uma página de preparação, inclusive esta.

A AAMC separa as questões do CARS em três categorias, e saber qual delas você está olhando muda o jeito de responder. Fundamentos de compreensão, cerca de 30 por cento da seção, pergunta o que o texto diz: a ideia principal, o sentido de uma expressão no contexto, o tom do autor. Raciocínio dentro do texto, outros 30 por cento mais ou menos, pergunta como o texto é construído: o que um parágrafo está fazendo ali, o que o autor assumiu sem dizer, se o apoio oferecido é forte o bastante para sustentar a afirmação. Raciocínio além do texto, cerca de 40 por cento, é o maior grupo e o que as pessoas subestimam. Ele entrega algo que o texto nunca mencionou, um caso novo, uma evidência nova, uma área totalmente diferente, e pede que você leve o argumento do autor até lá ou que diga o que o enfraqueceria.

Duas coisas no CARS surpreendem as pessoas. A primeira é que ler muito ajuda menos do que se espera e ter opiniões fortes não ajuda nada. Um assunto familiar tenta você a responder pela memória, e um texto que defende algo que você acha errado tenta você a responder pela discordância. As duas coisas custam pontos. A segunda é que as respostas erradas não são aleatórias. A maioria delas chega perto: extrema demais para o que o autor de fato disse, verdadeira no mundo mas nunca afirmada no texto, certa sobre metade da frase, ou uma afirmação correta que responde a uma pergunta que ninguém fez. Aprender esses quatro formatos vale mais do que aprender qualquer conteúdo, porque eles voltam em todo texto.

Como usar esta amostra

Esta amostra traz 15 questões em 15 trechos curtos, então ela troca a resistência para textos longos da seção real por cobertura dos tipos de questão. Cada trecho tem de 70 a 110 palavras e foi escrito pela equipe da StudyPDF no registro que o CARS usa. Eles não são textos reais do MCAT nem itens da AAMC. A mistura segue as categorias reais: algumas questões perguntam o que o texto diz, outras perguntam como o argumento é construído, outras entregam um caso novo ou um achado novo e pedem que você raciocine com ele. Três questões são de completar a lacuna, em que a palavra que falta é a que carrega a posição do autor, o que é um bom jeito de treinar a percepção de ressalvas, atenuações e a diferença entre uma afirmação forte e uma afirmação medida.

Faça tudo de uma vez, sem anotações e sem reler para sempre. Depois leia todas as explicações, inclusive as das questões que você acertou, porque uma resposta certa alcançada pelo caminho errado não se repete. Cada explicação aponta a frase que decide a questão e diz por que as outras alternativas falham. Acompanhe o formato dos seus erros, não a quantidade. Errar duas respostas extremas demais é um problema diferente de errar duas respostas fora de escopo, e as correções são diferentes. A primeira significa que você está arredondando o autor para cima, lendo uma afirmação cuidadosa como se fosse ousada. A segunda significa que você está respondendo a partir do seu próprio conhecimento em vez da página à sua frente.

Além de uma amostra, as pessoas melhoram no CARS com volume mais revisão, e a revisão é a parte que faz o trabalho. Faça um texto e, antes de conferir qualquer coisa, escreva uma frase dizendo qual era o ponto do autor e outra dizendo contra o que ele estava argumentando. Se você não consegue escrever essas duas frases, os erros foram de leitura, não de questão. Leia não ficção difícil sobre assuntos com que você não se importa, já que isso é o substituto diário mais próximo de um texto do CARS. Com o tempo, treine seções completas cronometradas, porque a seção é em parte um teste de resistência e nove textos seguidos não se parecem em nada com nove textos espalhados por uma semana.

Como a StudyPDF cria prática de CARS a partir do seu próprio material

Quinze questões conseguem mostrar quais hábitos de leitura estão faltando. Elas não constroem a resistência que a seção real exige, e nenhum conjunto fixo de questões continua funcionando depois que você já viu as respostas. O CARS é a seção em que a oferta de textos novos importa mais, porque reler um texto cuja resposta você já sabe não ensina quase nada.

A StudyPDF trabalha a partir do material que você traz. Envie seu livro de preparação para o MCAT, um caderno de CARS, suas próprias leituras do curso ou qualquer artigo denso em que queira treinar, e o Bo, o agente de estudo, cria questões de prática a partir dessas páginas exatas. Cada explicação cita de onde vem a resposta, então dá para voltar direto à fonte quando uma alternativa parecer discutível. Você pode gerar conjuntos novos quantas vezes quiser e mirar em uma habilidade só, por exemplo pressupostos não declarados ou questões de enfraquecimento, para treinar a categoria em que você continua perdendo pontos.

Você não precisa de documento nenhum. Se não tiver nada para enviar, diga um tema, por exemplo argumentos sobre a ética da memória ou relatos de viagem do século dezenove, e o Bo escreve o texto e as questões a partir disso. Começar é grátis. Tudo nesta página é prática para a prova, escrita pela equipe da StudyPDF a partir das categorias de questões do CARS publicadas. Não é orientação médica, não é material real da prova, e a StudyPDF não tem vínculo com a AAMC nem com nenhuma banca.
