In order to pressure the government of Country S to become

In order to pressure the government of Country S to become less repressive, some legislators in Country R want to ban all exports from R to S. Companies in R that manufacture telecommunication equipment
such as telephones and fax machines have argued that exports of their products should be exempted from the ban, on the ground that it is impossible for a country to remain repressive when telecommunication
equipment is widely available to the population of that country.

Which one of the following is a assumption on which the argument given by the manufacturers depends?

(A) The government of S has recently increased the amount of
telecommunication equipment it allows to be imported into the country.
(B) The telecommunication equipment that would be imported into S if the
exemption were to be granted would not be available solely to top government officials in S.
(C) A majority of the members of R’s legislature do not favor exempting
telecommunication equipment from the ban on exports to Country S.
(D) Of all exports that could be sent to Country S, telecommunication
equipment would be the most effective in helping citizens of S oppose that
country’s repressive government.
(E) Without pressure from Country R, the government of S would be able to continue repressing its citizens indefinitely.
