Assumption Ques

[ranjithreddy.k9]

Commentator: The theory of trade retaliation states that countries closed out of any of another country's markets should close some of their own markets to the other country in order to pressure the other country to reopen its markets. If every country acted according to this theory, no country would trade with any other.

The commentator's argument relies on which of the following assumptions?

(A) No country actually acts according to the theory of trade retaliation.
(B) No country should block any of its markets to foreign trade.
(C) Trade disputes should be settled by internation tribunal.
(D) For any two countries, at least one has some marked closed to the other.
(E) Countries close their markets to foreigners to protect domestic producers.

[spoiler]What is wrong with A??[/spoiler]

Between A and D here.

A negating this does not weaken the conclusion where two countries have some markets closed for each other.

D negating this means one country has either its market completely open or closed.This clearly violates the main premise mentioned and thus the conclusion.

Hence D here.

IMO: D...A is to extreme

The commentator's argument relies on which of the following assumptions?

(A) No country actually acts according to the theory of trade retaliation - There's no proof of this
(B) No country should block any of its markets to foreign trade. - Out of scope
(C) Trade disputes should be settled by internation tribunal. - Out of scope
(D) For any two countries, at least one has some marked closed to the other - Read from the end. Not all countries retaliate. So some countries have indeed closed their market, while the other might not have. If it had there would be no trade. And so answer is this.
(E) Countries close their markets to foreigners to protect domestic producers. - Foreigners is too broad a term in trade.

(C) Trade disputes should be settled by internation tribunal. (baseless judgement)
(D) For any two countries, at least one has some marked closed to the other.
(E) Countries close their markets to foreigners to protect domestic producers. (out of scope)
