Why would you place a question mark(s) within a sentence?

Placing a question mark within a sentence serves specific grammatical purposes that align more closely with options other than the one provided. In particular, using a question mark can denote that part of a sentence is phrased as a question, especially in cases of embedded or rhetorical questions.

Utilizing a question mark can highlight a rhetorical question, which is embedded within a statement but does not require an answer. This technique allows the writer to provoke thought or emphasize a point, even while maintaining the flow of the rest of the sentence.

Using question marks solely at the end of a sentence, as indicated in the first option, overlooks these valid grammatical structures and restricts the expressive possibilities of written communication. Therefore, understanding these nuances in punctuation allows for greater clarity and creativity in writing, particularly in silencing traditional rules when context calls for it.
