Answer 2

The answer is: Raghu is an engineer. He works very hard but doesn't get paid properly so his wife is disappointed and angry.

Here but and so is used because these two words add better meaning of the sentence.

The problem is hinted by “but” and so states the reason of the conflict of the sentence.

Here the sentence is formed in a way that keeps consistent with the whole extract.
