The local fair held its annual photography contest and accepted entries from both amateurs and professionals. The contest awarded prizes in each of several categories. As it turned out, most of the prizes in the contest were won by amateurs.
Each of the following, if true, could by itself constitute an explanation of the outcome of the photography contest EXCEPT:
(A) Many more of the entries in the contest were from amateurs than were from professionals.
(B) The judges in the contest were amateurs, and amateurs tend to prefer photographs taken by other amateurs.
(C) Amateurs tend to enter their best photographs while professionals tend to save their best work for their clients.
(D) Each category in the contest was restricted to amateurs only or professionals only, and there were more categories open to amateurs.
(E) Three times as many amateurs entered the contest as had entered in any previous year. - CORRECT. What 3 times is?? It may be more that professional or less than that. For example - CASE I: Professionals(This Year,TY) = 100, Amateurs(TY) = 300; Professionals(Last Year,LY) = 100, Amateurs(LY) = 100. It EXPLAINS.
CASE II: Professionals(This Year,TY) = 300, Amateurs(TY) = 300; Professionals(Last Year,LY) = 100, Amateurs(LY) = 100. It DOES NOT EXPLAINS.
As it goes in either direction, it is the correct choice.
Only A stands a little chance to confuse someone because it uses the word 'many' but it becomes clear when it uses it with 'more' i.e. 'many more' is more impactful.
Answer E.
