Read the passage: Roman engineers built their roads in layers. At the bottom was a bed of large stones, then a layer of gravel and sand, and on top a surface of tightly fitted paving stones. The surface was raised slightly in the center so that rainwater ran off into ditches on either side. Because water is the great enemy of any road, this drainage did as much to keep the roads in use for centuries as the stones did. Which statement best expresses the central idea of the passage?

1. Read the passage: Roman engineers built their roads in layers. At the bottom was a bed of large stones, then a layer of gravel and sand, and on top a surface of tightly fitted paving stones. The surface was raised slightly in the center so that rainwater ran off into ditches on either side. Because water is the great enemy of any road, this drainage did as much to keep the roads in use for centuries as the stones did. Which statement best expresses the central idea of the passage?
- A. Roman roads were made of stone because stone was cheap.
- B. The paving stones were the most important layer of a Roman road.
- C. Roman roads lasted because of how they were layered and how they shed water.
- D. Roman engineers built roads mainly to protect the army from rain.
Ver respuesta y explicación
Respuesta: C. Roman roads lasted because of how they were layered and how they shed water.
A central idea has to cover the whole passage: the layers and the drainage, and why both mattered. The paving stone option ignores the last sentence, which says drainage did as much as the stones. Cost and the army are never mentioned.
2. Read the passage: Glaciers move slowly, but not steadily. A glacier may creep forward only a few inches in a day, then surge ahead dozens of feet after a season of heavy snowfall. This uneven movement makes it hard to predict where the ice will be in ten years. As used in the passage, surge most nearly means
- A. move forward suddenly
- B. slowly melt away
- C. split into pieces
- D. stop completely
Ver respuesta y explicación
Respuesta: A. move forward suddenly
The sentence sets surge against creep, a few inches in a day, so it must mean the opposite: a fast, sudden advance of dozens of feet. The last sentence confirms it by calling the movement uneven and hard to predict.
3. Read the passage: Ines had rehearsed the speech on the bus, in the shower and twice for the cat. But now that the gym was full, the page in her hand seemed to belong to a stranger. She looked at the first line, then at the back wall, then at her brother, who was holding up a crooked sign that said GO INES in marker. Her shoulders loosened. She cleared her throat and began with the one sentence she had not written down. Which inference about Ines is best supported by the passage?
- A. She was unprepared because she had never practiced out loud.
- B. Her brother wrote the speech she is about to give.
- C. She is angry that the gym is so crowded.
- D. Seeing her brother steadies her, and she begins in her own words.
Ver respuesta y explicación
Respuesta: D. Seeing her brother steadies her, and she begins in her own words.
Her shoulders loosen right after she sees the sign, and she then starts with a sentence she did not write down, so she is calmer and speaks for herself. The passage lists several places she rehearsed, and nothing says who wrote the speech or that she is angry.
4. Read the passage: Each autumn, monarch butterflies in eastern North America fly south to spend the winter in the mountains of central Mexico. The trip can cover more than a thousand miles. The butterflies that head north again in spring, however, are not the ones that made the trip south. The journey north takes several generations, and each one lays eggs and dies along the way. Which statements are supported by the passage? Select all that apply.
Marca todas las que correspondan.
- A. Eastern monarchs spend the winter in the mountains of central Mexico.
- B. A single monarch flies the whole round trip each year.
- C. The trip back north takes more than one generation of butterflies.
- D. Monarchs fly south because food runs out in Mexico.
- E. The trip south can be more than a thousand miles long.
Ver respuesta y explicación
Respuesta: A. Eastern monarchs spend the winter in the mountains of central Mexico., C. The trip back north takes more than one generation of butterflies., E. The trip south can be more than a thousand miles long.
Three statements appear in the passage almost word for word. The round trip claim is contradicted, because the butterflies heading north are not the ones that went south, and the passage never gives a reason for the migration. Check every choice against the text, not against what you already know.
5. Read the sentence: The garden is tended by a different grade each week, the cafeteria serves the vegetables in its salad bar. Which version is punctuated correctly?
- A. The garden is tended by a different grade each week, the cafeteria serves the vegetables in its salad bar.
- B. The garden is tended by a different grade each week; the cafeteria serves the vegetables in its salad bar.
- C. The garden is tended by a different grade each week the cafeteria serves the vegetables in its salad bar.
- D. The garden is tended by a different grade each week, then the cafeteria serves the vegetables in its salad bar.
Ver respuesta y explicación
Respuesta: B. The garden is tended by a different grade each week; the cafeteria serves the vegetables in its salad bar.
The sentence is two complete thoughts, and a comma cannot join them, which is a comma splice. A semicolon can. Using no punctuation makes a run-on, and adding then after the comma still leaves two complete sentences joined by a comma alone.
6. Read the paragraph: (1) Last spring, students at Harbor Middle School planted a garden behind the gym. (2) Within months it had grown to eight raised beds, a compost bin and a rain barrel. (3) The principal's favorite food is pizza. (4) Students now sell extra vegetables at a stand every Friday. (5) The money pays for new seeds and tools. Which sentence should be deleted to keep the paragraph focused?
- A. Sentence 1
- B. Sentence 2
- C. Sentence 3
- D. Sentence 4
Ver respuesta y explicación
Respuesta: C. Sentence 3
Every other sentence is about the garden: where it started, how it grew, what happens to the vegetables and where the money goes. The principal's favorite food has nothing to do with the garden, so it breaks the focus.
7. Complete the sentence so the verb tenses stay consistent.
Students plant the seeds in spring and _____ the vegetables in fall, and the cafeteria _____ them in its salad bar.
Opciones para el hueco 1: harvest, harvested, harvesting, to harvest
Opciones para el hueco 2: serve, serves, served, serving
Ver respuesta y explicación
Respuesta: harvest, serves
The sentence is in the present tense, so the verb joined to plant must be harvest. The second blank needs a verb that agrees with the singular subject cafeteria, which is serves. The past tense would break the pattern, and an -ing form cannot stand alone as the verb.
8. Read the sentences: (1) The students planted a garden behind the gym. (2) They started with one raised bed. Which choice best combines them into one sentence?
- A. The students planted a garden behind the gym, starting with one raised bed.
- B. The students planted a garden behind the gym, they started with one raised bed.
- C. The students planted a garden behind the gym, but starting with one raised bed.
- D. Starting with one raised bed, a garden behind the gym was planted by the students.
Ver respuesta y explicación
Respuesta: A. The students planted a garden behind the gym, starting with one raised bed.
The first choice keeps the meaning and puts the describing phrase right next to the students it describes. The second is a comma splice, the third adds a but that makes no sense here, and in the fourth the opening phrase seems to describe the garden, not the students.
9. A recipe uses 3 cups of flour for every 2 cups of sugar. Which amounts keep the same ratio of flour to sugar? Select all that apply.
Marca todas las que correspondan.
- A. 6 cups of flour and 4 cups of sugar
- B. 4.5 cups of flour and 3 cups of sugar
- C. 9 cups of flour and 5 cups of sugar
- D. 5 cups of flour and 4 cups of sugar
- E. 1.5 cups of flour and 1 cup of sugar
Ver respuesta y explicación
Respuesta: A. 6 cups of flour and 4 cups of sugar, B. 4.5 cups of flour and 3 cups of sugar, E. 1.5 cups of flour and 1 cup of sugar
Multiply or divide both amounts by the same number. Doubling gives 6 and 4, multiplying by 1.5 gives 4.5 and 3, and halving gives 1.5 and 1. For 9 cups of flour you would need 6 cups of sugar, not 5, and 5 to 4 is a different ratio from 3 to 2.
10. A cyclist rides 18 miles in 1.5 hours at a steady speed. At this rate, how many minutes will it take to ride 30 miles?
- A. 120
- B. 150
- C. 180
- D. 250
Ver respuesta y explicación
Respuesta: B. 150
The speed is 18 divided by 1.5, which is 12 miles per hour. Then 30 miles takes 30 divided by 12, or 2.5 hours, and 2.5 hours is 150 minutes. The answer 250 comes from reading 2.5 hours as 250 minutes, and 120 and 180 are just whole numbers of hours.
11. Complete the solution.
A rectangle's length is 3 more than twice its width, and its perimeter is 36 units. Its width is _____ units.
Opciones para el hueco 1: 4, 5, 6, 7
Ver respuesta y explicación
Respuesta: 5
Call the width w, so the length is 2w + 3. The perimeter is 2 times the sum of the sides: 2(w + 2w + 3) = 36, so 6w + 6 = 36 and w = 5. Check: the length is 13, and 2 times 5 plus 2 times 13 is 36.
12. Complete the sentence.
Mina has $40. A notebook costs $9 and each pen costs $2.50. After buying the notebook, she can buy at most _____ pens.
Opciones para el hueco 1: 10, 11, 12, 13
Ver respuesta y explicación
Respuesta: 12
After the notebook she has 40 - 9 = $31. The inequality 2.50p ≤ 31 gives p ≤ 12.4, and she cannot buy part of a pen, so the most is 12. Rounding up to 13 would cost $32.50, which is more than she has.
13. A set of six numbers is 2, 3, 3, 5, 7 and 16. Which statements are true? Select all that apply.
Marca todas las que correspondan.
- A. The mean is 6.
- B. The median is 4.
- C. The mode is 5.
- D. The range is 14.
- E. The median is greater than the mean.
Ver respuesta y explicación
Respuesta: A. The mean is 6., B. The median is 4., D. The range is 14.
The numbers add up to 36, and 36 divided by 6 is 6. With six numbers the median is the average of the third and fourth, 3 and 5, which is 4. The range is 16 - 2 = 14. The mode is the most common value, 3, and the median of 4 is less than the mean of 6 because 16 pulls the mean up.
14. A fair number cube with faces 1 to 6 is rolled twice. What is the probability that the first roll is even and the second roll is greater than 4?
- A. 1/12
- B. 5/6
- C. 1/5
- D. 1/6
Ver respuesta y explicación
Respuesta: D. 1/6
The rolls do not affect each other, so multiply. An even first roll has probability 3/6, or 1/2, and a second roll of 5 or 6 has probability 2/6, or 1/3. Then 1/2 times 1/3 is 1/6. Adding 1/2 and 1/3 gives 5/6, which is the mistake of adding when the question asks for both.
15. A circular pool has a diameter of 12 feet. A walkway 2 feet wide goes all the way around the pool. What is the area of the walkway?
- A. 28π square feet
- B. 4π square feet
- C. 64π square feet
- D. 112π square feet
Ver respuesta y explicación
Respuesta: A. 28π square feet
The pool has a radius of 6 feet and the pool plus walkway has a radius of 8 feet. The walkway is the difference of the two circles: π times 64 minus π times 36, which is 28π. The 64π option is the whole outer circle, 4π squares only the width, and 112π uses diameters in place of radii.
Qué es el SHSAT y quién lo hace
El Specialized High Schools Admissions Test, o SHSAT, es el examen que usa la ciudad de Nueva York para decidir la admisión en sus institutos especializados (specialized high schools). NYC Public Schools lo llama el único factor, con una excepción: el LaGuardia High School admite por audición. Cualquier residente actual de la ciudad de Nueva York que esté en 8th grade, o en 9th grade por primera vez, y quiera solicitar uno de los demás centros tiene que hacerlo, tanto si el estudiante va a un centro público, privado o parroquial. Se hace en otoño para la admisión del septiembre siguiente.
El examen tiene dos secciones. English language arts (ELA) abarca la revisión y edición, es decir, corregir y mejorar textos breves, y la comprensión lectora. Math abarca razones y relaciones proporcionales, el sistema de numeración y las expresiones, ecuaciones, desigualdades, estadística y probabilidad, y geometría. NYC dice que las preguntas son de opción múltiple, de completar huecos y de tipo tecnológico mejorado (technology-enhanced), y que los estudiantes eligen con qué sección empezar.
El formato está cambiando. NYC administra el examen en ordenador, y su página describe un examen adaptativo por ordenador desde el otoño de 2026, en el que las preguntas se ajustan a tus respuestas. Como el material de preparación más antiguo puede no coincidir, esta página no indica número de preguntas, límite de tiempo ni puntuación. La página del SHSAT de NYC Public Schools en schools.nyc.gov muestra los datos vigentes, además de dónde y cuándo se hace el examen.
Cómo usar esta muestra
Las 15 preguntas siguen en miniatura las áreas de contenido publicadas. Las preguntas 1 a 4 son de comprensión lectora: una idea central, una palabra en contexto, una inferencia y los detalles que respalda un texto. De la 5 a la 8 son de revisión y edición: un empalme de comas (comma splice), una oración que sobra, el tiempo verbal y combinar dos oraciones. De la 9 a la 15 son de matemáticas: razones, una tasa, una ecuación, una desigualdad, estadística, probabilidad y el área de una corona circular.
Los formatos de marcar todas las que correspondan y de completar huecos son formatos de práctica que te obligan a revisar todas las opciones en lugar de parar en la primera que parece correcta. El examen real mezcla sus propios tipos de pregunta, así que usa la Student Readiness Tool de NYC y sus tests de práctica oficiales en línea para acostumbrarte a la pantalla y a las herramientas, y usa una muestra como esta para tener más preguntas sobre las habilidades.
Hazla de una sentada y resuelve las matemáticas en papel antes de mirar las opciones. Después lee todas las explicaciones, también las de las preguntas que acertaste. Un grupo de fallos es más útil que uno solo: si las preguntas de razones y de tasas salieron mal, eso apunta al razonamiento proporcional como la habilidad que practicar.
Una nota honesta: el equipo de StudyPDF escribió cada pregunta de aquí según las áreas de contenido que publica NYC. Ninguna es una pregunta real del SHSAT, ninguna sale de la NYC Guide to the SHSAT, de los tests de práctica oficiales ni del libro de una empresa de preparación, y StudyPDF no está afiliada a NYC Public Schools ni a ninguno de los centros.
