GMAT OFFICIAL QUESTIONS

1) To persuade consumers to buy its personal computers for home use, SuperComp has enlisted computer dealers in shopping centers to carry its product and launched a major advertising campaign that has already increased public awareness of the SuperComp brand. Despite the fact that these dealers achieved dramatically increased sales of computers last month, however, analysts doubt that SuperComp’s products accounted for much of that increase.

Which of the following, if true, best supports the claim that the analysts’ doubt is well founded?

In market surveys, few respondents who had been exposed to SuperComp’s advertising

campaign said they thought there was no point in owning a home computer.

People who own a home computer often buy a second such computer, but only rarely do

people buy a third computer.

SuperComp’s dealers also sell other brands of computers that are very similar to

SuperComp’s but less expensive and that afford the dealers a significantly higher

markup.

The dealers who were chosen to sell SuperComp’s computers were selected in part

because their stores are located in shopping centers that attract relatively wealthy

shoppers.

Computer-industry analysts believed before the SuperComp campaign began that most

consumers who already owned home computers were not yet ready to replace them.

 Success!

You answered "SuperComp’s dealers also sell other brands of computers that are very similar to SuperComp’s but less expensive and that afford the dealers a significantly higher markup." and that's correct because:

The passage states that the stores through which SuperComp is selling its computers are

experiencing dramatically increased sales. Analysts doubt, however, that SuperComp's

plan for selling tis computers for home use is really working. The question asks you to

identify a fact that justifies the analysts' doubt.

Choice C is the best answer. If consumers who are drawn to a SuperComp dealer find

less expensive alternatives that the dealer has a strong incentive to sell to them, the

analysts' doubt is justified, since it is likely that the increase in the dealer's sales is due

not to sales of SuperComp's computers, but rather to sales of these other brands.

Choice A is incorrect; it suggests that there is a market for home computers, so does

nothing to justify the analysts' doubts.  Choice B is incorrect because it provides

information about the consumers' buying inclinations, but does not provide justification for

the analysts' doubts, given that the dealers were actually selling more computers than

usual.  Choice D is incorrect since it suggests that SuperComp chose well-located

dealers, and does nothing to justify the analysts' doubts.  Finally, the beliefs mentioned in

choice E, which were formed before the campaign, cannot justify the analysts' doubts in

the face of the evidence about increased sales.
