Question

• the children were playing quietly, i had time to bake muffins.
• the children were playing quietly: i had time to bake muffins.
• the children were playing quietly; i had time to bake muffins.
• no change

Explanation:

Identify the grammatical error in the original sentence

The original sentence "The children were playing quietly I had time to bake muffins." consists of two independent clauses joined without any punctuation or coordinating conjunction, which is a run-on sentence (specifically, a fused sentence).

Evaluate the punctuation options

• Option 1 uses a comma to join two independent clauses, creating a comma splice.
• Option 2 uses a colon, which is incorrect here because the second clause does not explain, illustrate, or expand upon the first.
• Option 3 uses a semicolon, which correctly joins two closely related independent clauses without a coordinating conjunction.
• Option 4 ("no change") retains the run-on sentence.

Select the correct option

Option 3 correctly resolves the run-on sentence using a semicolon.

Answer:

• (A) The children were playing quietly, I had time to bake muffins.
• (B) The children were playing quietly: I had time to bake muffins.
• (C) The children were playing quietly; I had time to bake muffins. (Correct answer)
• (D) no change
