Which one of the following sentences contains a dangling modifier?
A. Adequate lighting is important for anyone who is studying or reading.
B. Drivers in our state are confused by the outdated driving law.
C. The contented puppy sat by the sleeping young child.
D. My brother had an old truck that sat by the garage that needed paint.
The modifier "that needed paint" is intended to modify the noun "truck," but it is placed ambiguously, suggesting that the garage needs paint instead. This creates a dangling modifier because it's not clear what the modifier is meant to modify.
Therefore, the Correct Answer is D.
