Mashika: We already know from polling data that some segments of the electorate provide significant support to Ms. Puerta. If those segments also provide significant support to Mr. Quintana, then no segment of the electorate that provides significant support to Mr. Quintana provides significant support to Mr. Ramirez.
Salim: But actually, as the latest polling data conclusively shows, at least one segment of the electorate does provide significant support to both Mr. Quintana and Mr. Ramirez.
Among the following statements, which is it most reasonable to infer from the assertions by Mashika and Salim?
At least one segment of the electorate provides significant support neither to Mr. Quintana nor to Mr. Ramirez.
At least one segment of the electorate provides significant support to Ms. Puerta but not to Mr. Quintana.
Each segment of the electorate provides significant support to Ms. Puerta.
Each segment of the electorate provides significant support to Mr. Quintana.
Each segment of the electorate provides significant support to Mr. Ramirez.
原本M说：如果P和Q有交集，那么Q和R就没有交集；然而S推翻了M的说法，S说Q和R是有交集的，那也就是说P和Q没有交集咯，所以B对。。。。。。
不存在S推翻了M的说法，S和M的说法都是对的，选项是建立在S和M都对的情况下。
