CL Mock CAT 11 [2018]

Hi,

I have recently wrote Mock CAT 11. In general equilibrium passage, question number 18, main idea - answer is 4. But I couldnt decide between options 2 and 4. I dont understand where the author has suggested for an atlernate economic theory. And also why option 2 is incorrect. Please explain.

varc-50 (18c/26a)  FINALLY back at 50 but ok ok accuracy

dilr-27(9c/9a) (back to basics)

qa-54(18c/22a) could've gone above 60 (im too slow at solving, or rather being too choosy )

OA-131 

I found the DILR section really difficult. Was is really?

CL MOCK 11 

VARC=>49

LRDI=>36 [ lack of practice ] 

QA=>57 [ 5 mistakes :o ] 

OA =>  142 

What the f is this mock? VARC, dropped from 92%ile (in mock 10) to 14%ile

I know it is probably not the right thread but I just need to know whether the percentiles of sectional tests are based on actual test-takers data or is it just an estimate ??

VARC 48

DILR 48
