the right answer really is 'E',and there is a trap in 'E'
First,why is 'B' wrong,see the explanation below:
D denotes demestic films,F denotes foreign films
category 1,rate=20%
D:100*20%=20
F:20*20%=4
category 2,rate=20%
D:500*20%=100
F:100*20%=20
overall rate(D)=(20+100)/(100+500)=120/600=20%
overall rate(F)=(4+20)/(20+100)=24/120=20%
SO,more domestic films don't mean higher overall rate.
Second,'E' says MOST F were submitted in CATEGORIES with low rates
As you see,that's the category which has low rate of acceptance,NOT F has the low rate of acceptance.That is really a trap which causes you to believe that 'E' contradics fact 1.
So:
category 1,rate=20%
D:100*20%=20
F:20*20%=4
category 2,RATE=5%
D:100*5%=5
F:400*5%=20
overall rate(D)=(20+20)/(100+100)=40/200=20%
overall rate(F)=(5+20)/(20+400)=25/420=6%(approximately)
as the calculation above,that most F were in category 2 and the rate of category 2 is extremely low both to D and F,causes the overall rate of F is around 6%
