Final answer:
The sentence that contains a dangling modifier in the passage is sentence A: "Moving at the age of 14 meant starting high school not knowing anybody or anything about the area." A dangling modifier is a word or phrase that is not clearly and logically related to the word it is supposed to modify.
Step-by-step explanation:
The sentence that contains a dangling modifier in the passage is sentence A: "Moving at the age of 14 meant starting high school not knowing anybody or anything about the area."
A dangling modifier is a word or phrase that is not clearly and logically related to the word it is supposed to modify. In this sentence, the phrase "moving at the age of 14" is the dangling modifier because it does not properly modify the subject of the sentence, which is "I". To correct this, the sentence could be rewritten as, "Starting high school at the age of 14 meant moving to a new area and not knowing anybody or anything about it."
