Voting is the privilege for which wars have been fought, protests have been organized, and editorials have been written. "No taxation without representation," was a battle cry of the American Revolution. Women struggled for suffrage, as did many minorities. Eighteen year olds clamored for the right to vote, saying that if they were old enough to fight in the war, then they should be allowed to vote. Yet Americans have a deplorable voting history, and many will tell you that they have never voted.

Which of the following words is the best synonym for the word 'privilege' as used in the passage?

The poor vote, the rich don’t. That’s the way it has traditionally been. Elections have, by and large, shown well-heeled neighbourhoods logging low voter turnouts compared to those less privileged-either because they’re cynical/disillusioned; or, have ‘better’ things to do with their time; or, don’t want to expose their delicate complexion to the burning sun; or, they’re doing okay with their lives, thank you very much.

Which of the following statements weakens the above argument?
