Question

senator means :
a member of a legislative assembly
a person who is advanced in years
a public educator at certain universities
a supporter of sacred texts as literal truth

Explanation:

A senator is defined as a member of a legislative assembly. For example, in the United States, senators are part of the legislative branch (the Senate). The other options: "a person who is advanced in years" is more related to the general concept of an elderly person; "a public educator at certain universities" is about an academic role; "a supporter of sacred texts as literal truth" is about a religious - related stance. None of these other descriptions match the common and official definition of a senator.

Answer:

a member of a legislative assembly
