A. While eating a croissant, Josh waved to the crowd. B. Covered in fluffiness, the couple played with the kitten. C. Having eaten lunch, the girl turned on the laptop. D. While playing, Lancaster jumped on the feathers.
The answer to this is B. What makes the modifier for this sentence wrong? The use of modifiers can be very important. There are some sentences that will change simply because of the modifier that has been placed. In this case, the modifier is put in such a way that it would be confusing if it is the cat that is fluffy or the couple.
The other sentences have the right modifier because the modifier emphasized the meaning of the sentence the correct way. When you check out the other choices, it is only letter B that seems confusing while all the others have clear meanings.
