Unless
Until
While
As if
Answer is Right!
Answer is Wrong!
The correct answer is: Unless.
The word “unless” is used to introduce a condition that must be met in order for something else to happen. In this case, the speaker is saying that the listener cannot pass unless they work very hard.
The other options are not as appropriate in this context. The word “until” is used to introduce a point in time at which something will happen. The word “while” is used to introduce a situation that is happening at the same time as something else. The word “as if” is used to introduce a comparison or a supposition.
Here are some examples of how the word “unless” can be used in a sentence:
- I won’t go to the party unless you come with me.
- You can’t leave the house unless you finish your homework.
- I’ll help you unless you don’t want me to.
