Answer:
E) Comput-o-Mart does not sell any computers that support only basic computing.
Step-by-step explanation:
Comput-o-Mart advertisement implies that if you buy a computer somewhere else, the salespeople will try to sell you expensive computers that are usually able to support complex computing activities, even though they could sell cheaper computers that are not that "powerful". But if Comput-o-Mart only sells powerful and expensive computers, then it should be no different than the other stores. At least somewhere else you can insist on buying a cheaper computer.
