If Country X does not intervene militarily in Country Y, then the whol

If C is correct as per your logic, Then the same logic applies to B and B has to be correct as well. There's only 1 answer though.

Two reasons why B&C are incorrect:
1- They point to only 1 side of the story. It doesn't explicitly state the other side.
2- Since the tone of the question is decisive, the tone of the answer shall also be decisive.

Oh yes!
I haven't paid attention to this. The concept of tone of the question is surely a thing I learnt here.

If A--> B

Than Not B--> Not A.(Always sure)


We can't say with surety that

Not A ---> Not B


That is why "e" is correct.

In my view, this is a case of necessary versus sufficient.
We know that Country X's not intervening means the whole region WILL DEFINITELY FALL. But, this does not imply that Country X's intervening in and of itself WILL PREVENT the fall under enemy influence. In other words, it may be NECESSARY for Country X to intervene, but not SUFFICIENT because there may be other factors that are required to prevent the fall of the region.

If Country X does not intervene militarily in Country Y, then the whole region will definitely fall under enemy influence.

It most logically follows from the statement above that, if Country X does intervene militarily in Country Y, then the whole region

(A) Will definitely fall under enemy influence X

(B) Will probably fall under enemy influence X

(C) Will probably not fall under enemy influence X

(D) Will definitely not fall under enemy influence X

(E) May or may not fall under enemy influence CORRECT

If Country X does not intervene militarily in Country Y, then the whole region will definitely fall under enemy influence.

(A) Will definitely fall under enemy influence - WRONG. Not at all.

(B) Will probably fall under enemy influence - WRONG. Falling is out of context under intervention situation.

(C) Will probably not fall under enemy influence - WRONG. Covers only a part of the inference. 2nd best.

(D) Will definitely not fall under enemy influence - WRONG. Absolutely wrong.

(E) May or may not fall under enemy influence. - CORRECT. If military intervention happens then X may win over enemy, leaving no influence over Y. If X doesn't win then there is influence. Hence this is the best choice we have.

Answer E.
