Negation

The glass is not always half full

Conditional i think

Negation is the easy one:

The glass is always half full.

Conditional is when one statement depends on the other:

If it is a glass, then it is not always half full.

(I think something like that maybe.)

Conjunction is when you connect two statements together with an OR:

It is a glass OR it not always half full.

(Not sure on this one, sorry).

Disjunction is when you connect two statements together with an AND:

It is a glass AND it is not always half full.

(Again, sorry, not sure if this is exactly what they're looking for.)
