Answer is D

Can the BTG experts help me attack this problem from parallelism perspective. I was so confused with the things that follow "but". (It took me a while to understand What's parallel with what during the exam, a situation that costed me about 3-4 mins ) What the best way to approach these questions.

Also in the exam tension I totally missed the split between " purchases that are refunded " and "purchase price is/are refunded", let alone subtle changes in the meaning and other one word change such as "primary goal is to... and "goal is to primarily create" - How does one effectively catch these splits.

My sincere thanks in advance.

Cheers
