PSAT Reading Question 609: Answer and Explanation

Question: 609

As used in line 10, "construct" most closely means

• A. building.
• B. observation.
• C. theory.
• D. astronomy.

Correct Answer: C

Explanation:

(C) On vocabulary questions, if there is any uncertainty, it is best to plug the options into the passage in place of the word. "Theory," in this case, makes far more sense than "building," "observation," or "astronomy." "Construct" isn't often used as a noun rather than a verb, but when it is, its meaning is generally an idea or a theory.
