Editorial: Any democratic society is endangered by segmentation into classes of widely differing incomes between which there is little mobility. Such class divisions strengthen divisive political factions that stand in the way of good governance. Since economic expansion gives people more opportunities to improve their economic standing, democratic societies should adopt policies that ensure constant economic expansion.
Which one of the following, if true, would most strengthen the reasoning in the editorial?The editorial argues that economic expansion can reduce the danger created by large income differences and limited mobility.
The best support would show that expansion actually helps
reduce those economic divisions.
(A) Discord within a society tends to increase inequities in the distribution of wealth.
Incorrect. This shows how discord may worsen inequality, but not how economic expansion would solve the problem.
(B) Political factions are sometimes willing to overlook their differences to back policies that are conducive to economic expansion.
Incorrect. This shows that factions may support expansion, but not that expansion reduces harmful class divisions.
(C) Economic expansion results in a proportionally greater increase in earnings for people at low income levels than for people at other income levels.
Correct. If lower-income people benefit proportionally more from economic expansion, the income gap between classes can narrow. This directly supports the claim that economic expansion can reduce the class divisions that threaten democratic society.
(D) Economic expansion cannot occur unless there is significant financial investment in the economy by people at the highest income levels.
Incorrect. This describes a requirement for expansion, not a benefit of expansion in reducing class divisions.
(E) The presence of divisive political factions can be an obstacle to economic expansion.
Incorrect. This shows that political divisions may hinder expansion, but it does not support the claim that expansion will reduce those divisions.
Answer: (C)
