Advertisement: HomeGlo Paints, Inc., has won the prestigious Golden Paintbrush Award—given to the one paint manufacturer in the country that has increased the environmental safety of its product most over the past three years—for HomeGlo Exterior Enamel. The Golden Paintbrush is awarded only on the basis of thorough tests by independent testing laboratories. So when you choose HomeGlo Exterior Enamel, you will know that you have chosen the most environmentally safe brand of paint manufactured in this country today.

The flawed reasoning in the advertisement most closely parallels that in which one of the following?

(A) The ZXC audio system received the overall top ranking for looks, performance, durability, and value in Listeners’ Report magazine’s ratings of currently produced systems. Therefore, the ZXC must have better sound quality than any other currently produced sound system.

(B) Morning Sunshine breakfast cereal contains, ounce for ounce, more of the nutrients needed for a healthy diet than any other breakfast cereal on the market today. Thus, when you eat Morning Sunshine, you will know you are eating the most nutritious food now on the market.

(C) The number of consumer visits increased more at Countryside Market last year than at any other market in the region. Therefore, Countryside’s profits must also have increased more last year than those of any other market in the region.

(D) Jerrold’s teachers recognize him as the student who has shown more academic improvement than any other student in the junior class this year. Therefore, if Jerrold and his classmates are ranked according to their current academic performance, Jerrold must hold the highest ranking.

(E) Margaret Durring’s short story “The Power Lunch” won three separate awards for best short fiction of the year. Therefore, any of Margaret Durring’s earlier stories certainly has enough literary merit to be included in an anthology of the best recent short fiction.

The Golden Paintbrush award is given to the product that has improved the most. That does not mean the product is the best -- the product might have been absolutely terrible a year ago, and merely average now. But the advertisement reaches the flawed conclusion that the product is the best. We want to find an answer choice that similarly confuses "most improved" with "best". Answer D does exactly that: in that answer, Jerrold has improved the most, and the answer choice then concludes he will rank ahead of all of his classmates.

Some of the other answers are vaguely close to right (e.g. in answer A, the argument confuses one set of qualities, durability and so on, with another, sound quality, and the original argument is also guilty of confusing one quality with another) but D is such a close parallel to the original argument that it is clearly the best answer.

So when you choose HomeGlo Exterior Enamel, you will know that you have chosen the most environmentally safe brand of paint manufactured in this country today.

Lets say HomeGlo Paints was only 10% safe in terms of env safety 3 years back and another brand X was 80% safe. Now after three years Homeglo paints has increased its safety level by 50% (highest increase in the market place of paints). This very impressive increase still doesn't make Homeglo the most environment safe brand of paint as there are other brands who had already achieved this % and might not have become 85% safe(% increase is less but overall safety is higher) D correctly matches the reasoning.
