Critical Reasoning

Can you explain why it's not A? If the background color is gold isn't the label undistinguishable? Thanks OA D

Mourdet Winery: Danville Winery's new wine was introduced to compete with our most popular wine, which is sold in a distinctive tall, black bottle. Danville uses a similar bottle. Thus, it is likely that many customers intending to buy our wine will mistakenly buy theirs instead.

Danville Winery: Not so. The two bottles can be readily distinguished: the label on ours, but not on theirs, is gold colored.

Which of the following, if true, most undermines Danville Winery's response?

(A) Gold is the background color on the label of many of the wines produced by Danville Winery.

(B) When the bottles are viewed side by side, Danville Winery's bottle is perceptibly taller than Mourdet Winery's.

(C) Danville Winery, unlike Mourdet Winery, displays its wine's label prominently in advertisements.

(D) It is common for occasional purchasers to buy a bottle of wine on the basis of a general impression of the most obvious feature of the bottle.

(E) Many popular wines are sold in bottles of a standard design.

I can see why (A) cannot be the answer, but even (D) is not that great an answer.

In order to weaken the argument, we have to show that the two bottles cannot be readily distinguished.

Choice (A) talks about only the label on the wine bottles of Danville Winery. It does not mention anything about Mourdet Winery's wine bottles. This choice is out of scope.

My only contention with choice (D) is the word "occasional" purchasers, whereas the conclusion in the first stem is that...it is likely that many customers intending to buy our wine.

What's the source of this problem?

It's GMATPrep.

Hi Experts,

Any idea what category would E fall into?

Is it irrelevant because we have no info if DW is popular or is it a weakener since M W is popular and hence sold in a standard bottle then there are chances that people will confuse it with other popular bottles. Please suggest?

The argument of MW (Mourdet Winery) is this -

DW (Danville Winery) uses a similar bottle --> Many customers will buy DW wine.

DW states that bottles can be readily distinguished because it uses gold colored labels.

DW tries to weaken MW's argument by giving a consideration that states that the effect mentioned above(many customers will buy DW wine) might not happen.
We have to weaken DW's argument. Any option that states that many customers will buy DW wine because of similarly shaped bottles is the correct answer.

A - strengthens DW's argument. Customers might be able to distinguish MW's wine from DW's wine because many people might associate DW's wines with gold colored labels.

B - strengthens DW's argument. If DW's wine bottle is perceptibly taller then people might be able distinguish MW's wine bottle from DW's wine bottle.

C - strengthens DW's argument. If it does that then probably people can easily distinguish MW's wine from DW's wine.

D - correct answer. It suggests that "occasional purchasers" will probably buy DW's wine thinking that it is MW's wine. Here obvious feature = tall distinctive black bottle.

E - not relevant. The argument is not talking about standard design, but about tall, distinctive black bottle.
