Choose the best option to fill in the blank.
① give
② gave
③ gives
④ sacrificed
⑤ gives up
⑥ sacrifices
⑦ worked
⑨ work
⑩ working
The answer is option 6, ‘sacrifice.’
Explanation: First, sacrifice is in the right tense. And word choice-wise it is practically a set expression, culturally, one knows it is right. Second, gives and gives up work grammatically, but gives up doesn’t make sense in the context of the sentence and meaning and gives is okay, but slightly off in nuance. This is the kind of thing one learns in cultural immersion in another country–or in class. You cannot learn it from grammar.
