This was a weird question for me. From the question stem, it seems like there would have been some lively debate between the two, but really we just have one sentence for each scholar.
Gombrich's position:
The emotions we feel in response to art aren't "true" emotions, but just memories of when we did feel such emotions.
(I'm surprised you didn't look up "ersatz", which is a very tough word ...
... it means "serving as a substitute; synthetic; artificial")
Radford's position:
'People
do experience
real melancholy or joy' ... this is a contrast with G, who thought that the emotions were not 'real'.
But these real emotions are irrational responses since people know the stimuli is fake.
Answer choices:
(A) True. R mentions irrationality and G doesn't.
(B) "Most psychologists", from 31-36, believe the emotions are 'genuine'. But G thought they were "ersatz", just remembrances. This is probably the answer.
(C) True. "Ersatz/Remembered" vs. "Real"
(D) True. G mentions "remembered" and R doesn't.
(E) True. Same as (C). "Artificial/ersatz" vs. "Real"
Hope this helps.
