What happens when the president vetoes a bill?

I heard If the president vetoes a bill, it is sent back to Congress with a message from the president explaining the reasons for his veto.They can do nothing, and the bill dies. They can vote to override the veto. If 2/3 of each house vote to override the veto, it becomes a law without the president's approval.

answer; i believe the correct answer is enlightenment;

there are no options provided but you can choose among the following gender-neutral pronouns: zir, hir, eir, vis, tem, eir.

in the normal course of maintaining a pronoun-antecedent agreement, we could have used the words his or her but since we are also required to use gender-neutral language, we need to replace it with its equivalent gender-neutral pronoun.
