Question

györgy buzsáki, the biggs professor of neuroscience at the new york university grossman school of medicine, conducted a study of mice brain cells to investigate ______. according to buzsákis research, certain experiences are immediately followed by five to twenty \sharp wave ripples\ of neurons that linger in the brain until sleep, during which the ripples are reactivated and consolidated into a lasting memory. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a how are mammalian experiences converted into permanent memories? b how are mammalian experiences converted into permanent memories. c how mammalian experiences are converted into permanent memories. d how mammalian experiences are converted into permanent memories?

Explanation:

This is a grammar question about the structure of a subordinate clause. In a subordinate clause (here, the clause starting with "how" that is part of the study's investigation), the word order should be subject - verb (not the interrogative word - order as in a question). Also, the sentence is a statement (the study investigates something, which is a statement of purpose), so it should end with a period, not a question mark.

• Option A: Has the interrogative word - order (how + are + subject) and a question mark. Since it is a subordinate clause (not a direct question), the word - order is wrong and the punctuation is incorrect.
• Option B: Has the interrogative word - order (how + are + subject). The word - order for a subordinate clause is incorrect.
• Option C: Has the correct subject - verb word - order (how + subject + are) and ends with a period (correct for a statement within the context of the sentence).
• Option D: Ends with a question mark. But the overall sentence is a statement (the study investigates...), so the punctuation is wrong.

Answer:

C. how mammalian experiences are converted into permanent memories.
