...and do you know how to make a full adder from gates?

If not, write out a truth table, you can always start there.

Edit: After realizing you have to use half adders, do you know how to connect them to form a full adder?

Where is the XOR gate coming into this -- you are asked to use two half-adders and an OR gate to make a full adder.

So it sounds like you need to look up what a half adder is and what a full adder is and how you can use half adders to make full adders.
