It isn't :)

I'm COMOPLETELY sure

Answer 25

lol typo

Answer 26

The example is supposed to prove the postulate WRONG. The example proves the postulate of D RIGHT.

Answer 27

How about C

Answer 28

That one is irrelevant to the example. It is not proven or disproved either way.

Answer 29

B! I'd say

Answer 30

The only one that makes sense is B. It says that if the product of two numbers is EVEN, BOTH NUMBERS are also even. The product in the example is even, so according to that postulate, both numbers being multiplied should be even. But of course 11 is odd, which proves the postulate WRONG. Ez

Answer 31

Sorry @jaclynbabe I can't help you :(
