I have some confusion interpreting the meaning of this text completion:
Because there are few things that (i)____________a scientist more than being told that something is (ii)________________, so called pundits should be more cautious in their pronouncements: the Wright Brothers took the sky at the very time when it was fashionable among experts to ridicule the likelihood of human flight-it was the experts who ended up looking foolish.
(i): startle, galvanize, discourage
(ii): impossible, mysterious, serendipitous
I'm able to somehow understand what goes in the second blank, which is "impossible" but can't understand the sentence structure "Because there are few things that__________a scientist more than being told that something is.."
The answer is galvanize, but why is it so? Why can't it be discourage? It could be said since they have only few things to be discouraged than pundits saying something is impossible, they weren't discouraged that much and took to the sky..
Can you explain what's wrong in my interpretation of the sentence structure?
