Question

Which one of the following is a run-on sentence?

A. Jerry told me he likes June, but Hank likes Julie better.
B. I would talk to Frank if I knew him, but people don't ever talk to him.
C. I'm not a fan of wrestling, but Leslie is.
D. I think Frank might be too busy he likes to make people think he's smart

Answer 1

The answer is definitely D, because it contains two independent clauses that are joined together without a comma or conjunction. (An independent clause just means a chunk of language that has both a subject and a verb and could be a complete sentence on its own.)

Answer 2

d is a run on sentence because there are no commas or periods and it is quite long
