Question

Identify the following group of words as an incomplete or complete sentence. If the sentence is incomplete, identify the reason.

When Euclid wrote The Elements

A.
complete sentence

B.
incomplete sentence: no subject

C.
incomplete sentence: subordinate clause

D.
incomplete sentence: no verb

Answer 1

Well it's definitely incomplete. There is a subject and there is a verb.

Answer 2

Even if you don't know the answer, you can always just use a simple process of elimination with this, even if you don't know the answer. A is off since it's a fragmented sentence, B is wrong since there is a subject (Euclid), and D is wrong since there is a verb (wrote; subject always comes before the verb). Knowing all this would just leave you with the conclusion that the answer would be C, subordinate clause.
