Let us first define the meaning of misplaced modifier; it is a word, clause, or phrase that is improperly placed in a sentence which make it refer or modify an unintended word.
The first, second, and third sentences that are given above sound correct because their modifiers are placed just right. Only the fourth sentence sounded awkwardly and confusing, because the clause "who lives in New York" is improperly separated from the subject "My aunt", which must be described in the first place, and not the "holidays".
The sentence will sound and can be understood better if it is written this way,
"My aunt, who lives in New York, is coming home for the holidays."
The correct answer is paraphrasing.
- - -
Instead of saying word-from-word what the person has told them and repeating it, they are saying "basically..."
"A Wedding Gift," the narrator's tone is serious.
the correct answer would be D. he tried different kinds of wood, coconut fiber, and even the hair because you see the word EVEN in between the AND and the THE, we'll the EVEN makes the sentence seem like the author is thinking that Edison really wants to succeed.
So D) is the correct answer.
