I don't understand what the difference between this question and PT112.S1.Q18 is.

Why does this conclusion not require the the assumption/trigger that public opinion of the sculpture is what Monica says it is? That would point us to AC B.

Meanwhile, in PT112.S1.Q18, you do require the assumption that the recent study was actually correct for the conclusion to trigger.

I don't understand the difference. #help

I don't understand why A isn't necessary—what if some participants drank neither coffee, nor tea, and served as a control group. If that were true, it's possible that the control group could have had an even faster immune system response than tea, thus implying that drinking tea actually slows the participants immune systems. #help
