The way this sentence is currently written, it sounds like the bus “gets ready” and then picks up the narrator; however, given the context, it would make more sense that the narrator is the one “getting ready.” To fix this sentence, we should specify who is really getting ready. The best replacement for the underlined phrase is to say “after I get ready.”

The way this sentence is currently worded, the phrase “waiting in the dark” sounds like it is describing the meteor; however, from the context, we know that it is actually the narrator who was waiting in the dark. To better communicate this idea, we can rephrase the sentence to specify who was waiting: “as I waited in the dark, a meteor left a bright trail in the black sky.”

As the sentence is written, the modifying phrase "leaving my house" is ambiguous, and could refer to the shooting star, which, hopefully, was not leaving "my house." The best way to correct the sentence would be to clarify both the time sequence, and the subject who was leaving the house: "as I was leaving my house." 

In the original sentence, the word "she" in the relative clause creates a certain ambiguity. The relative clause, as a modifying phrase, should not be ambiguous as regards the noun being described. In this case, the most effective way of re-writing the sentence is to separate the compound subject "My mother and sister," instead placing sister as an indirect object and putting the modifying phrase directly after the noun to which it refers.

As it reads, the sentence implies that the tree branch itself tripped while running, which makes no sense. "I" was running and the tree branch tripped "me." This is a misplaced modifier error.

The sentence as written makes it unclear who was "fishing at the lake," was it the rain? That doesn't make sense, rain can't fish! The correct answer clarifies that "I" was fishing while rain began to pour.

The singular pronouns in the second clause ("which" "it", "this") all have ambiguity issues since it is unclear what exactly her family is proud of. Two of the answer choices also create comma splices. The correct answer corrects the ambiguity by stating that it was Sarah's record of successful elections that is the source of her family's pride.

As it reads, the sentence sounds as though Anna's furniture was excited to move into a new home when it was Anna who was excited, and as such, Anna should be the one performing the action in the underlined portion of the sentence. Only two of the answer choices correct this error, but one of them is still incorrect and confusing in the order it places the actions that Anna performs-who or what did she quickly remove from the truck? "Anna quickly removed the furniture from the truck and assembled it" is the most clear and grammatically correct answer.

Which is ambiguous since there are several possible antecedents in the first clause that could have tarnished President Harding's legacy.

This and It are also ambiguous and also create comma splices.

They creates a comma splice.

The noun phrase a fact that eliminates the possibility of an ambiguous pronoun.

"Only" is a type of modifier called an adverb of degree, along with words such as "just," "almost," and "nearly." These adverbs of degree refer to the word directly following them, so in this case it seems like the author "only bought" socks, say, instead of renting them or borrowing them. It is clear from the context, however, that the author means to say that she bought socks and nothing else, so the appropriate placement for the modifier is directly before the word "socks."
