which sentence contains a dangling modifier?\narriving late for the movie, jack quietly took a seat.\narriving early to class, leslie had time to finish her homework.\nwithout hearing the instructions, i found that the assignment was difficult to complete.\nafter reading the whole book, the ending was unsatisfying.
Answer
Brief Explanations:
A dangling modifier is a word or phrase that modifies a word not clearly stated in the sentence. In "After reading the whole book, the ending was unsatisfying", the phrase "After reading the whole book" has no clear subject doing the reading. It seems as if the ending did the reading, which is incorrect. In the other sentences, the subject performing the action in the modifying phrase is clearly stated (Jack, Leslie, I).
Answer:
After reading the whole book, the ending was unsatisfying.
