Select the most appropriate option to fill in the blank.
We cannot quote a price ........... we are allowed to examine the sample.
Answer & explanation
Correct answer: option 2
The most appropriate option to fill in the blank is unless.
The word "unless" means "except if" or "only if". In this case, we cannot quote a price unless we are allowed to examine the sample.
The other options are incorrect.
- Except means "excluding" or "not including". It is not the correct word to use in this sentence because we are not excluding the possibility of quoting a price.
- Because means "for the reason that". It is not the correct word to use in this sentence because we are not giving a reason for not being able to quote a price.
- Whether means "if" or "whether or not". It is not the correct word to use in this sentence because we are not asking a question.
