What punctuation is needed in the following sentence to make it correct? Because of a major accident on the freeway, the emergency room was overcrowded.

  • A. Period
  • B. Comma
  • C. Exclamation point
  • D. Semicolon
Correct Answer: B

Rationale: The correct sentence should be: 'Because of a major accident on the freeway, the emergency room was overcrowded.' A comma is needed after 'freeway' to separate the introductory dependent clause from the independent clause that follows. Choice A (Period) is incorrect as it would create two separate sentences. Choice C (Exclamation point) is incorrect as there is no exclamation in the sentence. Choice D (Semicolon) is incorrect as it is used to separate closely related independent clauses.
