답이 2번인데 2번도 틀린 것 아닌가요? 찾아보니까 only위치가 명사 앞이어야 한다고 그러던데 왜 b가 맞고 나머지는 틀린거죠?

20. Which sentence uses the modifier correctly?

1. The kids quickly ate all that food.

2.  I only have one day to get this report finished.

3. The movie's exciting plot didn't improve it.

4.  Plunging into the water, he rescued the child drowning.

<Your Answer is Wrong>

Correct Answer: I only have one day to get this report finished.

Explanation: All except 'b' has the wrong placement of modifier. Only is the modifier of the sentence and it will be placed before the word it modifies. Otherwise, the meaning of the sentence will be changed.
