In the example sentence, it is not clear what the modifying phrase "Thrilled that the storm had finally broken" is referring to. Boots cannot be thrilled. In order to avoid a dangling modifier, a subject that can be appropriately modified by such a phrase must be included. The best way to change the underlined portion of the sentence above is: "the campers marched gleefully along the trail."

The sentence above contains an example of a squinting modifier. It is not clear if the word "vigilantly" is meant to modify how the old folks keep track of their health, or how they die from simple health complications. This error must be corrected by changing the position of the modifier. The best way to correct the underlined portion of the sentence above is: "Elderly people who don't vigilantly keep track of their health die from simple health complications."

The sentence is written with a dangling modifier, which makes the sentence read as though the "gruesome scene" was what was "coming back to the farm." The sentence needs to be restructured to clarify this problem. The only answer choice that does this is "everyone in the car saw the gruesome scene."

When a sentence begins with a dangling participle or descriptive phrase, the person or thing described in that phrase (in this case, "Neil") must immediately follow it. Only one answer choice does this correctly. The answer choice that begins "Neil's anxiety" may appear to do so, but it does not, because the possessive "Neil's" is no longer the subject, but is describing the anxiety.

The sentence as written contains a dangling modifier, as the construction of the sentence implies the skyscrapers are what is "coming around the corner." The word order can be changed to make this much more clear. The correct answer is "Coming around the corner, the people got a view of the skyscrapers across the river." 

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.
