The following text is adapted from a novel. [Grandfather] was as boisterous as my brother was silent. Even when he sat still, he made noise—tapping his cane, humming tunes, and rustling his newspaper.
Which choice best describes the function of the underlined sentence?
It explains why the narrator dislikes the grandfather.
It contrasts the grandfather’s behavior with the brother’s nature.
It suggests the grandfather is hard of hearing.
It describes a conversation between the grandfather and the brother.
Correct Answer: B
Choice B is the best answer. The sentence explicitly contrasts the "boisterous" grandfather with the "silent" brother.
Choice A is incorrect. Description doesn't equal dislike. Choice C is incorrect. Being loud doesn't mean he's deaf. Choice D is incorrect. It describes habits, not a dialogue.
