Almost the entire demand for milk products in Hamilton County is

When we negate option C, shouldnt this be reworded to say that the remaining centers sold the same/more volumes ( did not sell less ) of milk this year which totally crashes the conclusion where revenues fall ( if price is constant )?

The App is live by the way and can be downloaded from the Play Store. Search for gmat club forum.

Thx.

VeritasKarishma can you please help with this one. How is OA:E?? even if the company gets most of its biusiness from out side ( 51%). 49% is still domestic and could decrease sales significantly. Also no where does option E say that the revenues outside the city grew sufficiently to cover up the volume decline by closure of 4 local stores.

As u mentioned. this unstated premise should always be true. I can see various reasons in which option E could fail as an ans.

Thanks in advance.

"However, in the past six months, four of Mother Dairy distribution centers have closed down, and no new ones have opened up."
The above mentioned 4 Mother Dairy distribution centers, might have been closed down outside the Hamilton County. In this case, Option E doesn't hold.

Almost the entire demand for milk products in Hamilton County is supplied by Mother Dairy, a large establishment that has been around for fifty years, through distribution centers. However, in the past six months, four of Mother Dairy distribution centers have closed down, and no new ones have opened up. It is clear that Mother Dairy’s sales volumes and revenues this year will be less compared to those last year.
The argument depends on which of the following assumption?

A Mother Dairys sales volumes and revenues were much higher last year compared to the year before.
B Mother Dairys operating expenses have not seen a reduction from last year to this year.
C The distribution centers that have remained open have sold less volumes of milk this year than they did last year.
D Very soon, Mother Dairy will no longer be able to monopolize the milk market in Hamilton County.
E Mother Dairy is not one of the businesses that get most of their business from customers outside Hamilton County.

A,B,D is easy to eliminated. let's focus on C and E.

C is only have way correct. imagine what if the price of the milk go up significantly. will the conclusion " volumes and revenues this year will be less" still hold? For example, last year, it sold 10 units and with $10 per unit. because of the closure, the market price went up to $100 per unit. even though, it sold only 4 units this year, the total revenue is still higher than last year. 4*$100 = $400 vs 10*$10=$100

E is better. If most of their businesses are from outside of the county, it would surely not impact its business. Hence, it weakens the conclusion. But since it said "not" most of the businesses are from outside the county, meaning most of the customers are coming from Hamilton County. The dist centers closure would surely impact the revenue.

A , B and D - irrelevant

C)- active stores selling less is not an assumption required by the argument to justify conclusion , it can sell the same and still revenues will plummet

E) if it is that kind of a business and argument does not assume that it is - more sales from outside can make the difference of closed stores negligible.
