Hello, everyone. I know that an OE is provided in the spoiler, but sometimes such explanations focus more on the correct answer than on how to disprove the others. (I have not read through this particular OE.)

AutoCar is a car manufacturer in Country X. Over the past eight months, car sales in Country X have risen by more than 20 percent.
Therefore, AutoCar's sales over the past eight months have most probably risen by more than 20 percent.
The argument is flawed primarily because the author _____________.
The argument is simple: Because
car sales in general within Country X have increased by
more than 20 percent over a certain period of time, car sales for AutoCar within the same country and time period
have most probably risen by more than 20 percent. That seems a bit simplistic, right? We have no idea what the competition may look like or how large a market share AutoCar may have in Country X. What do the answer choices hold in store?
Quote:
(A) draws a general conclusion
based on a short period of timeThe duration for the sales figures is beside the point. Whether
eight months, days, or years may be considered, a legitimate comparison (of some sort) can still be made.
Quote:
(B)
fails to distinguish between a product and a brandExactly. AutoCar manufactures (and presumably sells) cars—
a product—and the argument applies general sales trends to AutoCar—
a brand—in particular. There is nothing to argue with in this answer choice.
Quote:
(C) fails to
distinguish between cars manufactured and sold in Country X, and cars manufactured outside Country X and sold in Country X Why does such a distinction need to be made? The argument is based on
car sales in Country X. Where those cars were produced does not affect these sales statistics.
Quote:
(D) draws a specific conclusion
based on a single caseThe attribution is incorrect. Rather, a specific conclusion is drawn from a
general pool of data, a sales trend on cars in Country X. If you want to argue that the
single case refers to
cars and that other types of products should have been considered, then, well, that would have nothing to do with the product manufactured by AutoCar, and the sales trend would be less applicable.
Quote:
(E) does not provide information about
any other car manufacturer in Country X other than AutoCar
Although this consideration could be seen as problematic for the argument, and it does touch on my earlier thoughts after reading the passage, it is not a logical flaw, especially because
any other car manufacturer could refer to just one. Maybe there are five such manufacturers in Country X, but if we had information on just two, the argument would be just as flawed. I would call this a second-best option, one that could weaken the argument in a different question altogether. But that brings us back to a CR fundamental: never lose sight of the question itself. We are asked to point out a logical flaw in
this particular argument, the one that says AutoCar probably had sales figures that fell in line with auto sales figures for the whole country. What underlies that assumption is a generalization, not necessarily a manufacturer-to-manufacturer comparison.
Perhaps the question makes more sense now. Good luck with your studies.
