Question

Which is a sentence fragment?

Answer 1

A sentence fragment is a group of words that look similar to a sentence but they aren’t. I believe #5 is correct

Answer 2

Answer: I would say 4 and/or 5

Explanation: A sentence fragment is a group of words that look like a sentence but doesn´t posses a subject or the subject it´s not clear at all.

Also, the complement of the sentence marks that something happened with the subject, but we´re not sure of it. So it can´t considered as a sentence because there´s a part of it that it´s blurred.
