Which choice most improves the underlined part of the sentence below? If the sentence is correct as is, choose (A).
A conjunction is used to connect words and sentences together.
A. words and sentences together.
B. words or sentences together.
C. words and sentences.
D. words or sentences.
E. words to sentences.
“Together” is redundant here. Would you ever connect something apart? We know then that (A) and (B) are out. Now the question is whether a conjunction is used to connect “words and sentences,” “words or sentences,” or “words to sentences.” The sentence is really trying to say that conjunctions are used to connect words to other words and sentences to other sentences. (C) and (E) both make it sound like conjunctions link words with sentences. The answer is (D).
