[D]

Country A's automobile industry's argument:
Foreign companies underpay workers and get cheaper materials. This enables them to keep prices low. Therefore, increase import tariffs, so that we have a level playing field (against them).

Response:
Other industries in country A manage fine. You don't need a tariff increase.

Question:
Slam the response.

Without even looking at the options, the most obvious way to slam the response is to indicate that different industries function differently. Other industries may manage fine, but the automobile industry likely has peculiar problems of its own. We're probably looking for an option that highlights this.

A) Out of scope in every way. Not relevant to the automobile industry. Not relevant to country A. Quality v Price is not relevant to the issue at hand (should import tariff be increased?)

B) If anything, this weakens the case for an increase in tax. Some countries are willing to give any amount of subsidy to offset any extra cost imposed on their country's automobile exporters. If country A raises import tax, this would be an extra cost imposed on the automobile manufacturers in other countries. So, that country might decide to increase the subsidy provided to its manufacturers. As a result, there may just be no difference due to the increase. Either way, this doesn't challenge the response ("there's no need for a tariff increase 'cause other industries manage fine.")

C) There are many industries in country A where their workers are paid more than workers in other countries are. The automobile industry is one of these, but others have an even greater disparity. This means other industries, faced with problems similar to the automobile industry, are managing just fine. This doesn't challenge the response ("there's no need for a tariff increase 'cause other industries manage fine.").

D) This indicates that the automobile industry in country A has a special problem. The parts used to make the automobiles have to be imported, and taxes have to be paid to other countries for these imports. Clearly, this shows that the automobile industry in country A is different from the others. So while the response says ["there's no need for a tariff increase 'cause other industries manage fine."], the automobile industry can turn around and indicate that they have problems unlike those of any other industry. - CORRECT

E) No other industry seems to need this tariff increase. The automobile industry in country A cannot possibly use this to challenge the response ("there's no need for a tariff increase 'cause other industries manage fine.")
