I like travelling by air _ _ _ __ __ the weather is bad.

B. Because
C. Unless
D. When

Answer 1

Hint:The sentences that we read and study in grammar are made up of a few, specific elements that help in forming the basic meaning of the sentence. We have read and studied about the subject, the object, the verb and the helping verbs that accompany verbs. We often tend to miss a small yet important element that combines two words, phrases or clauses. This element is the ‘conjunction’.

Complete answer:
The first option ‘while’ is a conjunction. Its meaning differs depending on the context where it is being used. When it is used as a noun, its meaning can be expressed over a period of time like, “We chatted for a while”. Whereas when it links two phrases or sentences as a conjunction, it indicates a contrast like “She wanted to eat rice while I was rooting for pasta”. It is not possible to like air travelling while the weather is bad.
If we look at option B, ‘because’ it won’t be the correct option too as ‘because’ the weather is bad, one person can’t like travelling by air.
‘When’ is used to indicate time. In the same logic it is also not possible.
Therefore, the word ‘unless’ is the only option which will be right here. The word ‘unless’ is used with a negative sense as if the weather is not bad, the person is narrating his likeness about the air travelling.

Hence the correct answer is option ‘C'.

Note:Sentences are formed by a few grammatical elements that bring out their basic meaning. These elements can be the subject, the object, the verb and the helping verbs. They form phrases and clauses which are connected by words that are known as conjunctions.
