The underlined phrase has a problem with the phrase "most learning." The phrase is describing the word "scholars." While the scholars might have "the most learning," this would make them "the most learned." The correct answer is "even the most learned of scholars."

The underlined phrase is extremely awkwardly worded, and can be cleaned up quite easily. "To find happiness" is the cleanest expression of the sentiment of the phrase's meaning.

The underlined phrase in the sentence is awkwardly worded, which makes the sentence itself difficult to understand. The "religious texts" contain contradictions, a meaning not conveyed properly by the sentence. "Contradicting themselves" is the clearest, most appropriate choice among the answers.

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."

With the sentence phrased the way it is, the thing that is "caring for a pet" appears to be "responsibility." This dangling modifier needs to be changed to make it clear that "children" are "caring for a pet." The correct answer choice is "Responsibility is something children can learn by caring for a pet."

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."

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."

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 answer choice "include family history, poor diet, and excessive stress" is correct because it contains appropriate parallelism—in this case, a list of three noun phrases.

The original text "include family history, poor diet, and having an excess of stress" and the answer choice "include family history, poor diet, and having an excessive amount of stress" contain faulty parallelism—the last item in the list includes the verb "having" whereas the first two items in the list do not employ verbs. These answers are therefore incorrect.

Answer choices "includes family history, poor diet, and excessive stress" and "tends to include family history, poor diet, and excessive stress" are incorrect because they both use singular predicates for the plural subject, "risk factors for cardiovascular disease."

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.
