Thanks for the question! This is a pretty tricky one and involves a careful reading of both answer choice (A) and the stimulus. Take a look at what the stimulus is arguing. Basically, because method actors actually experience the same emotions their characters are supposed to, whereas traditional actors just imitate them, the argument concludes that audiences will judge the performances of method actors to be more realistic than the performances of traditional actors. So the metric being used here is “realism,” the author is making a conclusion about realism.
Now take a look at (A), which tells us that performances based on an actor’s own experience of emotional states are more likely to affect an audience’s emotions than are performances based on imitations of the behaviors generally associated with those emotional states. What’s the metric being used here? Is it talking about realism? No, we’re being told about “affecting an audience’s emotions”! We can’t equate the two, and that’s why (A) is wrong.
Hope this helps! Feel free to ask any other questions that you might have.
