Which sentence contains a dangling modifier? 1) after walking in the blistering sun for two miles, the air-conditioned store felt like paradise. 2) having folded a week's worth of laundry, heather promised herself she would never wait this long again. 3) exhausted after running the marathon, antonio collapsed on the couch. 4) while feeding the dog, geri spilled dog food everywhere.

1) After walking in the blistering sun for two miles, the air-conditioned store felt like paradise

Explanation:

A dangling modifier happens when a word, phrase, or clause describes something or someone, but it is not clear to what or whom it refers.

In the case of the second option presented to us, it is clear that "having folded a week's worth of laundry" refers to Heather. In the third option, it is easy to understand that "exhausted after running the marathon" refers to Antonio. In the fourth option, Geri is the one to whom "while feeding the dog" refers to.

However, in the first sentence, we do not know to whom "after walking in the blistering sun for two miles" refers. It could be anyone. We need more context to make it clear. One way to solve this problem would be by adding the necessary information to the end of the sentence:

After walking in the blistering sun for two miles, the air-conditioned store felt like paradise to me.

the answer is the second one.
