Do you mean it sounds like "Boohs", if that's the case then it is "Booze"
Answer:
President
Explanation:
Here, George Washington is referred to as the first president of the United States—that is, the first in a number of presidents of the United States. Thus, in that example, president is a common noun.
The correct answer is his or her. Everyone is a singular indefinite pronoun; therefore, the singular form his or her agrees with the antecedent.
