Choices

5

Choice-A

Choice A is incorrect because, in this context, “attached” means connected or affixed. The text indicates that OSIRIS-REx gathered pieces of 101955 Bennu to bring to Earth; it doesn’t suggest that the spacecraft attached anything to the asteroid.

Wrong attached

6

Choice-B

Choice B is the correct answer because it most logically completes the text’s discussion of the OSIRIS-REx spacecraft’s contact with the asteroid 101955 Bennu. In this context, “collected” means acquired and taken away. The text indicates that although the boulders on the asteroid’s surface caused some unforeseen problems, OSIRIS-REx was able to gather a sample to return to Earth. This context suggests that OSIRIS-REx successfully collected a sample of 101955 Bennu.

Correct collected

7

Choice-C

Choice C is incorrect because in this context “followed” means tracked or travelled behind and the text discusses OSIRIS-REx’s brief encounter with 101955 Bennu during which the spacecraft gathered a sample to bring to Earth. The text doesn’t suggest that the spacecraft tracked the sample, and it’s not clear what it would mean for the spacecraft to travel behind the sample it collected.

Wrong followed

8

Choice-D

Choice D is incorrect because, in this context, “replaced” means put back or returned. The text indicates that OSIRIS-REx gathered pieces of 101955 Bennu to bring to Earth but doesn’t suggest that anything was returned to the asteroid.

Wrong replaced
