Answer 2

In which sentence can't we use "could"?

The sentence in which we can't use "could" is sentence 3: "They were not able to build a new garage." In this sentence, "could" cannot be used as a substitute for "were able to" because it would change the meaning of the sentence. "Could" implies the possibility or capability to do something, whereas "were able to" indicates that they actually accomplished the action. Therefore, using "could" in this sentence would suggest that they had the possibility to build a new garage but did not necessarily do so.
