PT6.S2.Q3 - All students at Pitcombe College...

Rev_Lefe

Hi, Thank you for your time. Please take a look at the following stimulus:

All students at Pitcombe College were asked to label themselves conservative, liberal, or middle-of-the-road politically. Of the students, 25 percent labelled themselves conservative, 24 percent labelled themselves liberal, and 51 percent labelled themselves middle-of-the-road. When asked about a particular set of issues, however, 77 percent of the students endorsed what is generally regarded as a liberal position.

Could someone explain how do I know "or" in the first sentence is exclusive or inclusive? There is no information that each student can only label itself once or by one label.

Thank you very much.

You don't, and it doesn't matter for this question. If 77% endorsed the position, some each group have to have supported it, even if the three categories were completely overlapped.
