5 on 5!!!

@jcalebb I would say that in strengthening and weaken questions you can, and they will force you to make assumptions in the answer choices.

@EllaLoy Hey! Conditional logic is like a big puzzle and as they mentioned earlier, what the statements say doesn't matter, what matters is the form at which they are presented. The rule that helped me the most is that we can't inverse the relationships between the arrows. Therefore:

If late (Sufficient) --> Then 5+ (Necessary)

NOT if 5+ --> then late.

it's the same as

if I am in the empire state building -> then I am in NYC

NOT if I am in NYC -> then I must be in the empire state building

That confuses sufficient for necessary and that's why the Kumar example is wrong.

The only true relationships you can assume is your conditional If -> then statement and the contrapositive:

If not 5+ --> then not late
