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.

The modifying phrase beginning the sentence must also modify the subject of the main clause. Ancient Greece cannot be skeptical. The only logical subject is philosophers.

The sentence as written contains a dangling modifier, as it is constructed in a manner that makes it seem as if "the path" is "unaware of" "any problems ahead." To correct this, the sentence's word order needs to be reversed so that the introductory phrase is immediately followed by the noun it describes—"the convoy," not "the path." "Unaware of any problems ahead, the convoy followed the path for miles" is the only answer choice that corrects this error. "Unaware of any problems ahead, the convoy following the path for miles" is incorrect because "following" is acting as a participle (that is, like an adjective describing "convoy"), and so the sentence does not contain a predicate and is thus a fragment.

In the sentence, the word "walking" is a dangling modifier, as it is confusing which noun is modified by the action of "walking into the room." The sentence is written in a way that makes it the conference table, and the word order needs to be moved around to clear this up; therefore, the correct answer choice is "the interviewee's vision was dominated by the conference table."

Here, “seething with anger” needs to describe who comes right after the comma. Thus, “Seething with anger, I slammed the door behind me” is the only answer choice that makes sense.
