Central Ideas and Details Question 5:

The history of science is replete with instances where accidental discoveries have led to significant advancements. One notable example is the discovery of X-rays by Wilhelm Röntgen in 1895. While experimenting with cathode rays, Röntgen noticed that a fluorescent screen in his laboratory started to glow, even though it was not in the direct path of the rays. Further investigation revealed that he had discovered a new form of electromagnetic radiation, which he called X-rays.

Which choice best describes the overall structure of the text? In the Here and Now Storybook (1921), educator Lucy Sprague Mitchell advanced the then controversial idea that books for very young children should imitate how they use language, since toddlers, who cannot yet grasp narrative or abstract ideas, seek reassurance in verbal repetition and naming. The most enduring example of this idea is Margaret Wise Brown's 1947 picture book Goodnight Moon, in which a young rabbit names the objects in his room as he drifts off to sleep. Scholars note that the book's emphasis on repetition, rhythm, and nonsense rhyme speaks directly to Mitchell's influence.

  1. The text outlines a debate between two authors of children's literature and then traces how that debate shaped theories on early childhood education.
  2. The text summarizes an argument about how children's literature should be evaluated and then discusses a contrasting view on that subject.
  3. The text lists the literary characteristics that are common to many classics of children's literature and then indicates the narrative subjects that are most appropriate for young children.
  4. The text presents a philosophy about what material is most suitable for children's literature and then describes a book influenced by that philosophy.

Answer (Detailed Solution Below)

Option 4 : The text presents a philosophy about what material is most suitable for children's literature and then describes a book influenced by that philosophy.

Choice D is the best answer. The text starts by introducing Mitchell's philosophy about using simple, repetitive language in books for young children. Then it describes a book influenced by that philosophy, Goodnight Moon. Choice A is incorrect. Although two authors are mentioned in the text, they both agree about the type of language that should be contained in books for young children. Choice B is incorrect. The text never discusses the evaluation of children's literature. It does provide one view of how children's books should be written, but never introduces a competing view. Choice C is incorrect. The text doesn't mention 'many classics of children's literature.' Instead, it describes an educational theory and identifies one example of a famous children's book that was influenced by that theory.

Which choice best states the main idea of the text?

The following text is adapted from Guy de Maupassant’s nineteenth-century short story “The Trip of Le Horla” (translated by Albert M. C. McMaster, A. E. Henderson, Mme. Quesada, et al.). The narrator is part of a group traveling in a hot-air balloon at night.

The earth no longer seems to exist, it is buried in milky vapors that resemble a sea. We are now alone in space with the moon, which looks like another balloon travelling opposite us; and our balloon, which shines in the air, appears like another, larger moon, a world wandering in the sky amid the stars, through infinity. We no longer speak, think nor live; we float along through space in delicious inertia. The air which is bearing us up has made of us all beings which resemble itself, silent, joyous, irresponsible beings, peculiarly alert, although motionless.

"

  1. The narrator feels a growing sense of isolation even though his companions are nearby during the balloon ride.
  2. The narrator and his companions are completely absorbed in the change in perspective they gain while riding in the balloon.
  3. The narrator and his companions are troubled by the disorienting effects of the altitude while riding in the balloon.
  4. The narrator is pleasantly surprised by his companions’ unrestrained enthusiasm about the sensation of riding in the balloon.

Answer (Detailed Solution Below)

Option 2 : The narrator and his companions are completely absorbed in the change in perspective they gain while riding in the balloon.

Central Ideas and Details Question 8 Detailed Solution

Choice B is the best answer because it most accurately states the main idea of the text. The narrator describes the view he and his companions have from the balloon: the earth lies beneath "milky vapors," and the balloon itself looks like another moon. The narrator goes on to explain how the people riding in the balloon are affected by the ride, explaining that they are immersed in the experience: floating along in "delicious inertia," or inactivity, like "silent, joyous, irresponsible beings." Thus, the main idea is that the narrator and his companions are completely absorbed in the change in perspective they gain while riding in the balloon.

Choice A is incorrect because the narrator never describes himself as feeling isolated from his companions; instead, he characterizes riding in the balloon as an experience he is sharing with them. And although he does imply a sense of isolation, it is isolation from those on the ground, as when he says of himself and his companions, "We are now alone." Choice C is incorrect because the narrator doesn’t suggest that he or his companions are troubled by the effects of the balloon ride. Instead, he describes himself and his companions as "joyous" and the experience of floating in the balloon as "delicious." Choice D is incorrect because nothing in the text suggests that the narrator is surprised by his companions’ response to the balloon ride. In fact, the text indicates that the narrator and his companions are having the same experience: they’re described as "silent" and "motionless," rather than as having unrestrained enthusiasm.

What is the main idea of the text?

The following text is adapted from William Shakespeare’s 1609 poem “Sonnet 27.” The poem is addressed to a close friend as if he were physically present.

Weary with toil, I [hurry] to my bed,

The dear repose for limbs with travel tired;

But then begins a journey in my head

To work my mind, when body’s work’s expired:

For then my thoughts—from far where I abide—

[Begin] a zealous pilgrimage to thee,

And keep my drooping eyelids open wide,

"

  1. The speaker is asleep and dreaming about traveling to see the friend.
  2. The speaker is planning an upcoming trip to the friend’s house. 
  3. The speaker is too fatigued to continue a discussion with the friend.
  4. The speaker is thinking about the friend instead of immediately falling asleep.

Answer (Detailed Solution Below)

Option 4 : The speaker is thinking about the friend instead of immediately falling asleep.

Central Ideas and Details Question 9 Detailed Solution

Choice D is the best answer it most accurately states the main idea of the text. The speaker describes going to bed for “repose” (rest) but finding that his thoughts are focused on the friend the speaker is addressing, and the thoughts are keeping the speaker awake.

Choice A is incorrect because the speaker isn’t asleep; the thoughts about the friend are keeping the speaker awake. Choice B is incorrect because the speaker isn’t talking about taking a literal trip; rather, the speaker uses the metaphor of a journey to describe internal thoughts. Choice C is incorrect because the speaker isn’t having a discussion with the friend.

  1. The era was characterized by consistent prosperity.
  2. The era was marked by extreme contrasts and contradictions.
  3. The era was uniformly bleak and oppressive.
  4. The era was a time of scientific progress and discovery.

Answer (Detailed Solution Below)

Option 2 : The era was marked by extreme contrasts and contradictions.

Central Ideas and Details Question 10 Detailed Solution

Choice B is the best answer because the passage highlights the contradictory nature of the era by juxtaposing phrases like 'the best of times' and 'the worst of times.' Choice A is incorrect because the passage does not suggest consistent prosperity. Choice C is incorrect because the passage indicates both positive and negative aspects, not uniform bleakness. Choice D is incorrect because, while scientific progress might be inferred, the passage does not explicitly mention it.
