To avoid economic collapse, Russia must increase its GNP by 20%. However, due to the structure of its economy, if the 20% threshold is reached, then a 40% increase in GNP is achievable.

Assuming that the above statements are true, which one of the following must also be true?

(A) If ethnic strife continues in Russia, then a 20% increase in GNP will be unattainable.
(B) If a 40% increase in Russia's GNP is impossible, its economy will collapse.
(C) If Russia's GNP increases by 40%, its economy will not collapse.
(D) If the 20% threshold is reached, then a 40% increase in GNP is achievable and a 60% increase is probable.
(E) If Russia's economy collapses, then it will not have increased its GNP by 40%.

go for E

I think it's 'only if' pattern.
economic doesn't collapse --> must increase its GNP by 20%(a 40% increase in GNP is achievable)

if economic collapses --> must not increase its GNP by 40%

Oh, must remember myself fault.

if A then B <> if no A, then no B.

if A then B == if no B, then no A.

1) To avoid economic collapes, Russia MUST increase GNP by 20%.
2) Due to structure of its economy, if 20% threshold is reached, then a 40% increase in GNP is achievable.

Assuming that the above statements are true, which one of the following must also be true?

(A) If ethnic strife continues in Russia, then a 20% increase in GNP will be unattainable.
- Not sure how ethnic strife comes into the picture. A is out.

(B) If a 40% increase in Russia's GNP is impossible, its economy will collapse.
- Not nescessarily. We're told the GNP of 40% is achieveblae. Nothing about whether it's possible or not.

(C) If Russia's GNP increases by 40%, its economy will not collapse.
- This is the one. To increase by 40%, it must have reached the 20% threshold and so the economy will not collaspe.

(D) If the 20% threshold is reached, then a 40% increase in GNP is achievable and a 60% increase is probable.
- Out. We do not know what's probably, could be any percentage.

(E) If Russia's economy collapses, then it will not have increased its GNP by 40%.
- No. It could have reached teh 20% threshold, but did not achieve the 40% mrk.

C it is.

Hi, I think it's a bit of weird.

In the passage:
To avoid economic collapse, Russia must increase its GNP by 20%.

but if Russia increase its GNP by 20%, its economic may or may not collapse.

In other words, even if it increase its GNP by 40%, we still cannot reach the absolute result.

I think "increase in GNP" is a necessary but not sufficient condition.
So E prevails.

but if Russia increase its GNP by 20%, its economic may or may not collapse.

In other words, even if it increase its GNP by 40%, we still cannot reach the absolute result.

What the passage is saying:

To avoid economy collaspe, Russia's GNP must be raised by 20%.
So if their GNP is raised only by 19.9%, the economy will collaspe.

Then it says if the GNP does managed to be raised to 20%, then there is a possibility that the GNP could go up and hit 40%.

In C, we're told that Russia's GNP increases by 40%. To be able to even achieve this, it must first reach the 20% threshold, and this is the only condition that will prevent an economy collaspe.

C for me...

If it reaches 20% it would avoid collapse and also it may even streach the percentage to 40%....

"B"

stem...If 20% not achieved (no X )----> then Y (economy collapse) ---(1)

Also ....If 20% is achieved (X)----> then 40% is possible (Z)

so.....If no Z (40% not possible) --> then no X (20% is not achieved) --(2)

From 1 and 2

If no Z (40% not possible) ----> then Y (economy collapse)...that's what "B" is saying.

"C" is out becose 20% is a necessary but may or may not be a sufficient condition to avoid collapse.

go with E)...

B) should be out because the economy can reach the 20% and NOT the 40% and the economy will not collapse

C) should be out because it still could collapse in the future.

if A then B
so
if not A then not B

Minimum requirement is 20% increase.
if economy collapses then it must be true that the GNP didnt increase by 20% (which means it didnt increase more than 40%)

definitely (E).

I disagree with u here Anand....I think 20% increase is the required condition but not sufficient one.....economy can still collapse even with a 20% increase.

baner, how can B) be true when the economy do not pass the 40%, but rests at 20% ? then the economy won`t collapse and the increase of 40% was not reached ("impossible"). the situation (no collapse) lasts with or without the passing of 40%.

Christoph, we need to realize that "B" is not talking abt if 40% is not reached , it is talking abt if 40% is impossible ....two different things....as the stem says ......if 20% threshold is reached then 40% is possible....that means if 40% is impossible then 20% threshold is not reached (if X, then Y concept) , hence the collapse.

my first vote was wrong because E) cannot be true because the economy could still collapse for some other reason...

A) Irrelevent
B) No C -> No A CORRECT LOGIC
C) C -> A Wrong Logic
D) B -> C -> D Wrong
E) Not A -> Not C Wrong Logic
