Question 2

And in the sufficient

Cannot be broken up without changing the meaning

A & B -> C

If you incorrectly write A->
B-> C

Then either item can set of the change when both are needed. It effectively changes it to or based on a mistake in shorthand.

Question 3

And in the Necessary

Answer 3

A-> B & C

A sets off both B and C without needing anything else. So it can be written as A-> B
->C
Without changing any meaning.

Question 4

Or in the Sufficient

Answer 4

A or B > C
Either option may give you c so you can split them apart and write it like this
A-> C
B-> C

A-> B or C

A must give you either B or C alone or unless the question directly says it can’t then you can get both.
