Correct Answer:
A. The boy turned on the Xbox after finishing the assignment.
This question focuses on sentence correction, specifically identifying and fixing a dangling modifier. A dangling modifier occurs when the subject of the modifying phrase is not the same as the subject of the main clause.
- Correct Answer A: The boy turned on the Xbox after finishing the assignment. The original sentence, "Having finished the assignment, the Xbox was turned on by the boy," contains a dangling modifier. "Having finished the assignment" logically refers to the person who finished the assignment, which is "the boy." However, grammatically, it appears to modify "the Xbox," implying the Xbox finished the assignment. Option A correctly rephrases the sentence, making "The boy" the clear subject performing both actions, thus resolving the dangling modifier and improving clarity.
- Incorrect Answer B: This option makes the dangling modifier even worse, suggesting the Xbox turned on the boy.
- Incorrect Answer C and D: These options are grammatically incomplete and awkward, lacking proper sentence structure and clarity.
