Identify a common punctuation error with introductory participial phrases and provide a correct fix.

• A. A misplaced introductory participial phrase; fix by placing the participial phrase next to the noun it modifies, e.g., "Running to catch the bus, he slipped."
• B. Using a comma splice.
• C. Omitting a comma after the introductory phrase.
• D. Placing a semicolon after a dependent clause.

Answer: (A)

Introductory participial phrases must attach to the noun they describe; placing them with the wrong word creates a confusing or incorrect reading where the modifier seems to describe someone or something it doesn’t actually describe. This is why the best choice shows the phrase clearly tied to the subject of the sentence. In the example, “Running to catch the bus, he slipped,” the opener describes the subject “he,” and the comma marks the boundary before the main action, so the sentence is clear and natural.

If the phrase were connected to the wrong noun, like describing the bus instead of the person, it would mislead readers and feel ungrammatical. Other listed errors—like a comma splice, omitting a comma after the introductory phrase, or using a semicolon after a dependent clause—are different punctuation issues and don’t address the core idea of correctly attaching the introductory participial phrase to its intended noun.
