Hi all
I cannot find any reason why (C) is wrong here.
It seems to me that (C) eliminates one alternative cause (genetic cause?) and thereby strengthen the argument that P-fat is responsible for the development of eyesight.
I compared (C) with (A) in S4Q17 in the same PT. (A) eliminates one possibility alternative by saying that "Earth did not pass through clouds of cosmic dust earlier than 800,000 years ago. This is because it negates an possibility that something other than fluctuation might have caused ice-age if the ice-age had occurred earlier than 800,000 years ago when the fluctuation started to happen. (A) turned out to strengthen the argument. Then, why does (C) not strengthen the argument? (I mean Q14)
Thank you very much
