The student wants to emphasize the aim of the research study. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A
As it orbited the Moon, the Kaguya satellite collected data that was later analyzed by cosmochemist Kentaro Terada.
B
Before 2008, Kentaro Terada wondered if the Moon was receiving some of its oxygen from Earth.
C
Cosmochemist Kentaro Terada set out to determine whether some of the Moon’s oxygen was coming from Earth.
D
Kentaro Terada’s study determined that Earth is sending a small amount of oxygen to the Moon.
Explanation
Correct answer: C.
Choice C is the best answer. The sentence emphasizes the aim, or goal, of the research study, noting what Terada set out to do: determine whether some of the Moon’s oxygen was coming from Earth.
Why the other choices are wrong
Choice A
Choice A is incorrect. The sentence focuses on how the Kaguya satellite collected data; it doesn’t emphasize the aim of the research study.
Choice B
Choice B is incorrect. While the sentence mentions what Terada was curious about before conducting the research study, it doesn’t emphasize his study’s aim.
Choice D
Choice D is incorrect. The sentence presents the research study’s conclusion; it doesn’t emphasize the study’s aim.
