(choose the sentence with a similar meaning)
1. In the hope finding the money they didn’t call the police
A They found the money, so there was no need to call the police
B They thought they might find the money, so the police weren’t called
C The knew they would find the money, so they didn’t call the police
D If they found the money or not, they wouldn’t call the police
I chose B but the answer is C.
Anyway, I think none of them is correct. B is poorly written and C is somehow far from the original meaning
As far as the sentence with a similar meaning, I agree with you. Sentence B is closest. C is definitely not right. We do not equate "in the hope of" with "knowing they would".
