Read the excerpt below from "civil peace" by chinua achebe and answer the question that follows.

at first he went daily, then every other day and finally once a week, to the offices of the coal corporation where he used to be a miner, to find out what was what. the only thing he did find out in the end was that that little house of his was even a greater blessing than he had thought. some of his fellow ex-miners who had nowhere to return at the end of the day's waiting just slept outside the doors of the offices and cooked what meal they could scrounge together in bournvita tins. as the weeks lengthened and still nobody could say what was what jonathan discontinued his weekly visits altogether and faced his palm wine bar.

why did jonathan return to the offices of the coal corporation?

to tell the other ex-miners about his house
to see if the ex-miners wanted to buy palm wine
to see if he could get his old job back
to give his ex-miner friends money and food

According to the information in the passage,the most appropriate answer would be To see if he could get his old job back. The reason for this is implicit in the passage. The expression "to find out what was what" can be interpreted as a person looking for an answer, besides, there is no other clue as to why would he be visitng the company he used to work for.

From the passage, it is not possible to infer any interaction between Jonathan and his colleagues, so thinking that he would have given money or food to them is not quite possible,as there is not a clue whether he was selling them palm wine or talking about his house.  

to see if he could get his old job back
