Which of the following is an example of a run-on sentence?

A) Lindsey was exhausted she had not gotten enough sleep for weeks.

B) Although she was positive she had finished her homework.

C) The garden was in full bloom; the sunflowers were the tallest.

D) The music was incredibly loud, and Sheila loved every song.

Answer: A) Lindsey was exhausted she had not gotten enough sleep for weeks.

Two or more independent clauses which are not conjoined or punctuated correctly constitute an error called a run-on sentence. The example given has an independent clause “Lindsey was exhausted” and another one “she had not gotten enough sleep for weeks” and they should be separated by proper punctuation and a conjunction.

Option B is a sentence fragment. Option C is a compound sentence with two independent clauses, which are correctly linked by a semicolon. Option D is a compound sentence with two separate clauses connected by the conjunction “and”.

To fix the run-on sentence in Option A, you can use either a period or a semicolon to separate the clauses, or you can join them with a conjunction, e.g., “Lindsey was exhausted as she had been not sleeping properly for several weeks.”
