Question

Which of the following is an example of a run-on sentence?      A. The garden was in full bloom; the sunflowers were the tallest. B. The music was incredibly loud, and Sheila loved every song. C. Lindsey was exhausted she had not gotten enough sleep for weeks. D. Although she was positive she had finished her homework

Answer 1

It is c. Lindsey was exhausted she had not gotten enough sleep for weeks.
{there is no punctuation, so the sentence just runs on; and makes no sense.}

Answer 2

The run-on sentence , in this case is option C "Lindsey was exhausted she had not gotten enough sleep for weeks". The sentence does not have a comma (,) to separate the clauses, they are not properly connected. however, they make sense in isolation. "Lindsey was exhausted" and "she had not gotten enough sleep for weeks" . They are just put together.
