In Country X's last election, the Reform Party beat its main opponent, the Conservative Party, although pollsters, employing in-person interviews shortly before the vote, had projected a Conservative Party victory. Afterwards, the pollsters determined that, unlike Conservative Party supporters, Reform Party supporters were less likely to express their party preference during in-person interviews than they were during telephone interviews. Therefore, using only telephone interviews instead would likely result in more accurate projections for the next election.

Which of the following statements, if true, would most support the argument in the passage?

A. The number of voters in Country X's next election will be significantly larger than the number of voters in the last election.
B. The Conservative Party will win the next election.
C. For each person interviewed in telephone polls before the next election, pollsters will be able to reasonably determine the likelihood of that person voting.
D. People who expressed no party preference during the in-person interviews shortly before Country X's last election did not outnumber the people who expressed a preference for the Conservative Party.
E. In the next election, pollsters will be able to conduct more in-person interviews than telephone interviews.

C
