Digital SAT Reading and Writing Test 3 Question 2

Which choice completes the text with the most logical and precise word or phrase?
Answer:
C

Explanation

Scientists at NASA’s Goddard Institute for Space Studies are examining weather patterns in the Arctic region to determine whether global warming has a noticeable effect on the magnitude of storms in the area—that is, to determine if changes in global temperatures correspond with a discernible fluctuation in storm intensity.

Choice C is the best answer. If changing global temperatures coincide with a fluctuation in storm intensity, that would mean that global warming has an effect on the storm intensity. The word "noticeable" means clear or apparent, and therefore it accurately describes the effect of global warming that scientists can observe on the magnitude of storms.

Choice A: "continuous" means unceasing. The text does not indicate whether the effect of global warming is unceasing.

Choice B: "universal" means all-encompassing. However, the text explicitly states that the scientists are simply looking for any discernible change in storm intensity.

Choice D: "subtle" means not obvious or apparent. However, the text clearly states that the effect is supposed to be discernible.

✨ Expert's Tip ✨

Recognize that “a discernible fluctuation in storm intensity” is parallel to the effect of global warming on the magnitude of storms.
