The sentence as it is written contains a dangling modifier, because it is unclear who or what was "hoping." The sentence needs to be rewritten to make it clear who is actually doing the "hoping." The answer choice that does this best is "Hoping to make amends, the young man gave his girlfriend the flowers."

The sentence is written in such a way to make it seem like the "project" was "making plenty of mistakes." The sentence needs to be reworded and restructured to show that it was "the young associate" who was "making plenty of mistakes." The correct answer choice is the only answer choice that makes this clear, "The project was taken away from the young associate because he was making plenty of mistakes."

The sentence contains a dangling modifier, making it seem as though the "parade" was "walking into the street." The sentence needs to be rearranged to make it clear that the "pedestrians" were walking. The only answer choice that does this is "Walking into the street, the pedestrians had their path blocked by the parade."

The sentence is written in such a way that it makes it seem like "the wallpaper" was "moving into his new house." The sentence needs to be rearranged to show that the "homeowner" is actually the one doing the moving. The only answer choice that does this is "the homeowner completely renovated the wallpaper."

The sentence is written in such a way to make it appear that "cooking a meal" is what is "under a great deal of stress." The sentence needs to be rearranged and reworded to clarify this confusion. The answer choice that does this best is "Cooking a meal was too hard for the newly-promoted manager, who was under a great deal of stress."

The sentence is written in such a way that it makes the finish line appear to be the one "making the final turn," instead of "the dueling cars." The sentence has to be rearranged to make this distinction clear, and still keep the sentence's intended meaning. The only answer choice that appropriately does this is "The finish line loomed for both of the dueling cars making the final turn."

The sentence is constructed in such a way as to make it seem that "the rainbow," rather than "the hikers," came over the hill. The sentence needs to be rearranged to clarify its meaning. The only answer choice that accomplishes this is "The rainbow became visible to the hikers as they were coming over the hill."

The sentence is written in such a way as to make it appear the car was "making a little more money." The sentence needs to be rearranged to show that the "young woman" was the one "making a little more money." The only answer choice that does this and becomes gramatically correct is "The new car was more affordable for the young woman who was making a little more money."

The sentence is written in a confusing way, making it read as though the city was "spreading" instead of the "massive fire." The sentence should be clarified to show that it was the fire that was "spreading," which will also allow a passive construction to change to an active construction. The answer choice that does this and is sensibly arranged is "the massive fire destroyed the city."

As it is written, the sentence is quite confusing, reading as though the counter was "Turning around." The underlined portion of the sentence can be rewritten to show both that the "harried man" is turning and get rid of the passive voice construction of the sentence. The only answer choice to properly achieve both of these goals is "the harried man ran into the counter."
