What if the GDP of EEC had fallen by 1000 in 1990
in that case the difference doesnot account for a rise in standard of living
So answer is D

IMO A
premise 1 - diff in GDP $5000
Assumption - population increase at same %
premise 2 - diff in GDP now $6000
Conclusion - Living standard definately increased

What is OA?

Its D,

logic being.

Lets assume there are 2 numbers A and B . The difference between them is 5.
A- B = 5.

after say some mathematical operation the difference became 6
A-B = 6.

So, the difference rose by 1. Now this is only possible in 2 cases.

either A increased or B decreased.

Only way A could have increased is incase B either remained constant or the decrease in B was less than 1.

So D holds true, if the GDP of Eu was not lower than 1000 in 1990 then that means there was some increase in GDP of country A and so the standard of living improved.

The answer D although is the best correct one, it has some flaw in reasoning.
Answer D says that GDP per capita in EU did not decrease by no more than $1 000 in 1990 than in 1990.

If the decrease was lower than $1000, the assumption would hold perfectly true, since for 6000 increase in difference to hold true, at most $999 drop in GDP per capita of EU is necessary at worst case scenario.
The answer D assumes that the drop in GDP per capita in EU could be straight $1000
Thus let's say GDP per capita in 1980 in country A was $ 6000 and in EU $ 1000
Then let's say in 1990 it was still $6000 for Country A and EU's GDP per capita dropped to zero! (We can assume that from answer D). The conclusion that living standards improved in country A will not hold true then, as u can see from my example.

D is the best answer but it has the above mentioned flaw, what do u guys think?
