This is how I worked on this problem,
I think that the main conclusion is the 1st sentence of argument “recently stated that the company was in terrible shape and headed for a disastrous year.” Saying this cuz this is someone’s opinion, and concluded that the firm is in bad shape.
Now, why he concluded that, cuz this “His concern was that, since the introduction of the AutoSnip III last year, [b]calls to the customer service line have nearly doubled, indicating that people are very unhappy with the new product.” So the bold part is here, supporting the main conclusion.
So, “The customer service line handles not only complaints but also sales, and the majority of the new calls have been to place new orders.” Saying that slas are growing. Bold here is a counter premise, directly opposing the main conclusion which is on the other side.
Hence, I think correct should be A. The first provides evidence supporting the main conclusion of the argument; the second provides evidence supporting a conclusion( that company is doing good) that the argument opposes ( that is not doing good).
I don’t go for B since my understanding says that the boldfaces are opposing to eachoter, and B is having both on the same side.
I kindly ask for any opinions here, Thanks
