I need help with this question subject reliability, credibility , and contextualization

i think its toxic gasses but i could be wrong

president reagan was a good presidant and should be presidant if he was still alive

explanation:

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.
