Syndicated political columnists often use their newspaper columns to try to persuade readers to vote a certain way. However, their efforts to persuade voters rarely succeed, for by the time such a column appears, nearly all who will vote in the election will have already made a decision about which candidate to vote for.
Which one of the following is an assumption required by the argument?
(A) Syndicated columnists influence the votes of most of their readers
who have not yet decided which candidate to vote for. - WRONG. Appeals to different set of people from what passage mentioned.
(B) The attempts of syndicated political columnists to persuade readers to vote a certain way in an election can
instead cause them to vote a different way. - WRONG. Irrelevant.
(C) People who regularly read columns by syndicated political columnists
mainly read those written by columnists with whom they already largely agree. - WRONG. Tells nothing about the opinion of the voters/readers.
(D) Regular readers of columns by syndicated political columnists are
less likely to be persuaded to vote a certain way by such columns
than are people who seldom read such columns. - WRONG. 2nd besst for me. Ruined by a comparison that modifies the situation.
(E) People
rarely can be persuaded to change their minds about which candidate to vote for once they have made a decision. - CORRECT. Had they been made to do so the situation in passage falls apart. The aspect presented by "however" would not hold as it is.
Answer E.
