Political scientists Andrea Rossi and Joanne Simmons analyzed an array of elements that affect citizen participation in Italian elections. Utilizing poll information that indicated whether participants cast their votes in national contests and how acquainted participants are with political issues, Rossi and Simmons assert that the propensity to vote is partially determined by prospective voters' assurance in their evaluations of candidates - fundamentally, the more educated voters are about politics, the more secure they feel in determining whether candidates align with their beliefs, and therefore, the more probable they are to vote.10 Mark For Review10Which choice best describes data in the table that support Rossi and Simmons's assertion? A) At every point on the political inclination spectrum, well-informed voters were more likely than less-informed voters to cast their ballots. B) Only less-informed voters who identify as independent had a voting probability below 50%. C) The closer that less-informed voters are to the extremes of the political inclination spectrum, the higher their likelihood of voting. D) Well-informed voters were more likely to identify as staunch leftists or staunch rightists than less-informed voters were.

They use that information to predict how the election will turn out.
