Averee is said to be intrinsically motivated.
She is motivated by her desire to selflessly help people due to the fact that she enjoys what she does. She is not motivated by her desire to get money or fame (that would be extrinsic motivation), but rather the goodness of her heart to help others feel better.
If all members of the House of Representatives votes, then at least 290 must vote to override. If all 100 Senate members vote, then at least 67 must vote for the veto.
Hope this helped:)
