The algaita is a double reed wind instrument from West Africa. The reed of a wind instrument is the mouthpiece

Question

The algaita is a double reed wind instrument from West Africa. The reed of a wind instrument is the mouthpiece blank A double reed contains two pieces of cane that vibrate and produce sound as air passes between them.

Which choice completes the text so that it conforms to the conventions of Standard English?

Accepted Answer

Choice C is the best answer. The convention being tested is end-of-sentence punctuation. This choice correctly uses a period to punctuate a declarative sentence ("the reed of a wind instrument is the mouthpiece") that ends with a prepositional phrase ("where sound is made"). Choice A is incorrect. It&rsquo;s unconventional to use a question mark to punctuate a declarative sentence. Choice B is incorrect. The structure requires that the sentence continue as a declarative clause, not end with an interrogative clause. Choice D is incorrect. The structure requires that the sentence continue as a declarative clause and end with a period, not end with an interrogative clause and a question mark.
