Verbal (CR)
An economic or political crisis in a poor country can lead to a lack of faith in the country's leaders, which is often followed by violent behavior, dissent, and even revolt among specific segments of the population. In many cases, propaganda is immediately issued from media outlets that quells such reactions by downplaying the extent of the recent crisis, thereby helping to restore belief in the efficacy of the government. However, the habitual violence exhibited by certain groups of disaffected youths in such countries generally has nothing to do with a lack of faith in their leaders, but rather is the consequence of an endemic boredom and lack of any vision of a positive future for themselves.
Which of the following statements follows most logically from the statements in the passage above?
(A) It is easier to quell periodic revolts in poor countries than it is to solve the habitual problem of youth violence.
(B) In all poor countries, propaganda alone cannot entirely diffuse dissent stemming from an economic or political crisis.
(C) Economic and political crises do not lead to any instances of youth violence in poor countries.
(D) The effect that propaganda has in putting down revolts in poor countries is primarily related to its ability to alter people's fundamental beliefs.
(E) To the extent that propaganda may help to decrease youth violence in a poor country, it is probably not the result of restoring the youths' faith in their country's leadership.
