Question: 1 / 400

Which word or words best complete the sentence? Due to library policy, patrons must set cell phones to vibrate and speak ______ in conversation.

quieter

quietly

The correct completion of the sentence is achieved with "quietly" because it serves as an adverb, modifying the verb "speak." Adverbs are utilized to describe how an action is performed, which is essential in this context as it indicates the manner in which patrons should engage in conversation within the library.

Using "quieter" would incorrectly suggest a comparative adjective form that does not fit the grammatical structure of the sentence, as it does not appropriately modify the verb "speak." "More quiet" likewise represents a comparative form but is less commonly accepted in conversational English than its adverbial counterpart. "More quieter" incorrect because it uses both "more" and the comparative ending “-er," creating a redundancy in the comparative form. Therefore, "quietly" is the best fit, aligning with proper syntax and ensuring clarity in the instructions given to patrons.
