What is the main idea of the passage?

  1. The human brain is as complex as it is mysterious.
  2. Patients with damaged amygdalas are less aggressive than individuals with healthy ones.
  3. Electrode stimulation is a valuable tool for researchers who study the human brain.
  4. Scientists have learned a lot about how the amygdala affects human emotion.

Answer(s): D

Explanation:

The passage is focused on the amygdala and how scientists have studied its relationship with emotions such as fear and aggression. The other answer choices are too specific or too broad. The correct main idea will always match the scope of the passage.





In the context of the passage, “accommodate” means to

  1. arrange lodging for
  2. contain
  3. make allowances for
  4. excuse

Answer(s): C

Explanation:

For vocabulary-in-context questions, always look up the word to see what it means in the context of the passage. Here, we are looking for a word or phrase that means something like “facilitate the proper viewing of” the different focal points. “Make allowances for” means “adjust for” or “compensate for,” which is what lenses ‒ either those in the eye or those in eyeglasses ‒ must do. "Arrange lodging for," meaning “house” or “put up,” is another meaning of “accommodate” but does not apply in this context, so it is incorrect. "Excuse," meaning “remove blame from” or “disregard,” does not apply in this context either.





The author of the passage would probably agree with which of the following statements relating corrective lenses and aging eyes?

  1. A dancer with a broken bone needs a cast to protect it.
  2. A hiker reinforces a fraying backpack strap with duct tape.
  3. A traveler gets a passport before going abroad.
  4. An athlete stretches before a game to avoid a potential injury.

Answer(s): B

Explanation:

To answer this question, we must go back to the passage to see what it says about how corrective lenses aid the eye. The last sentence of the passage states that the corrective lenses "do the work that the eye can no longer do for itself." We need to find a similar relationship: something doing work that can no longer be done by something else. The correct answer describes such a relationship. The damaged strap can no longer fulfill its task; the duct tape bolsters the strap so it can do the task instead. The frayed strap cannot repair itself, so the situation is not temporary.





What was the author’s primary purpose for writing this essay?

  1. to define what presbyopia is
  2. to describe how eyes age and the function of corrective lens
  3. to compare and contrast nearsightedness with farsightedness
  4. to review the anatomy of the human eye

Answer(s): B

Explanation:

The passage describes how the eye loses some of its functionality as a person ages and how corrective lens work to do the work that the eye can no longer do for itself.
