The sentence as written contains a dangling modifier, in that "the sun" is not what is "coming upon the hills." The sentence needs to be rewritten to show that the travelers were the ones "coming upon the hills." "As the travelers came upon the hill, the sun began setting behind them," is the correct answer choice.

The best answer fixes the dangling participle that starts the sentence (the subject of the main clause should be the one doing the action described in the opening phrase), and uses a logical coordinator.

As it is written, the initial sentence suggests that the speaker and author of the term paper is a murderous dictator, which is almost certainly not the speaker's intended claim. To fix this, we need to bring the modifying clause closer to the person to whom it is referring. One way that we can do that is by reversing the order of the two clauses.

This sentence has a dangling participle; its word order separates "forced to draw a freehand map of the United States" from its object, "her," by a significant amount. The sentence can be made clearer by making sure that the object described by its introductory phrase immediately follows that phrase. The best answer choice, "she suddenly forgot all of her knowledge of geography," fixes this and keeps the adverb “suddenly” close to its verb, resulting in the sentence, "Forced to draw a freehand map of the United States, she suddenly forgot all of her knowledge of geography."

The original text contains a misplaced modifier, making it sound as though the food critics were the ones who studied traditional French cuisine.

Only the answer choice "the master chef received praise from critics for her culinary innovations" avoids the misplaced modifier error because it places the person who did actually study traditional French cuisine—the master chef—immediately after the introductory modifying phrase.

The sentence as it is written contains a dangling modifier, because it appears that "the time" is "walking down the street." We need to rewrite the sentence so that it is apparent that "Erica" is the one who is "walking down the street." So, the correct answer is "Walking down the street, Erica lost track of the time."

The sentence features a dangling modifier, making it seem like the "aircraft carrier" is the object "alighting," when in fact the plane "alights" on the carrier. To remedy this, the words must be rearranged to make the plane the subject of the sentence. "The plane shook the aircraft carrier with its force," is the only answer choice that does this and is completely grammatically correct.

The sentence as written contains a dangling modifier, which confusingly makes it read like the park was what rounded the corner. The only answer choice that fixes this issue and is grammatically correct is "As the tourists rounded the corner, the park was right in front of them."

The sentence indicates with its final phrase that the "prom date" was the one on the stairs, but is written like the "young boy" is the one "descending." The introductory phrase needs to be restructured to make this distinction clear. The only answer choice that does this is "As she descended the stairs."

The sentence is confusingly written, as the modifier clause "Under the heavy weight" reads as though it is describing the rock. Actually the "people trapped underneath" are the ones "Under the heavy weight," and the sentence should be reworded to reflect this and clear up the confusion. The answer choice that does this and becomes clear is "the people trapped underneath the rock were being crushed."
