Nathan recently participated in a public opinion poll. Now he is thinking back on some of the questions he was asked and how he responded. Nathan thinks he recognizes evidence of a halo effect in one of his replies. Which of the following yes-or-no questions is most likely to have produced it? Should people be allowed to educate their children at home?

Should groups have the right to contribute money to opposition candidates in closely contested election campaigns?

Should sexually explicit magazines be excluded from check-out lanes, where children could otherwise view them?
