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."

The sentence is written in a way that makes the "higher rocks" seem to be the ones that are "making the climb." The sentence needs to be restructured and rearranged to show the "mountaineers" are the ones "making the climb." The answer choice that best straightens out this issue is "Higher rocks would continually fall on the mountaineers while they were making the climb."

The way the sentence is written, it appears that the neighbors were "moving into a new neighborhood" as a large mass. In fact, the sentence could be improved by emphasizing that the "odd family" was doing the moving. The answer choice that best clears up this confusion is "The neighbors were suspicious of the odd family moving into a new neighborhood."

The sentence is written in such a way to make it seem as though the "full display of jewels" was doing the "walking" instead of "the tour group." The sentence should be restructured to clarify this confusion, which can also get rid of the passive voice construction. The answer choice that best clarifies the meaning of the sentence is "the tour group saw the full display of jewels."

The sentence is written in a way that makes it appear that the "degree" was "taking classes at night," rather than the "young woman." The sentence must be rearranged and restructured to properly indicate who or what is doing the action of the sentence. The answer choice that best clarifies the sentence is "The degree came slowly to the young woman who was only taking classes at night."

The sentence is written in such a way to make the sentence read as though "the beard" was "coming into his own." The sentence needs to be rearranged and restructured to show it was the teenager was "coming into his own." The correct answer choice, which also eliminates the passive voice construction, is "Coming into his own, the teenager grew the beard to make himself look older."

The sentence is written in such a way that "the underbrush" was "running down the hill," and this confusion needs to be clarified. To do this, the sentence needs to be rearranged so that the introductory participial phrase, "Running down the hill," is as close as possible to the noun that it describes, "the boy." Two answer choices rearrange the sentence in this way: "Running down the hill, the boy fell into the thorny underbrush" and "Running down the hill, the boy fell into the underbrush that was thorny." The first of these options is the best because saying "the underbrush that was thorny" instead of "the thorny underbrush" is redundant.
