Question

1. in both the democratic and republican parties, a committee decides on _____.

the members of the congressional caucus
the partys nominees for president and vice president
the place and date of the national convention
the number of delegates to the convention

Explanation:

In US political parties (Democratic and Republican), the committee decides the place and date of the national convention. Congressional caucus members are not decided this way, nominees are chosen via primaries/caucuses and then confirmed at the convention, and the number of delegates follows party rules/state laws, not committee decision for place/date.

Answer:

C. the place and date of the national convention
