The roman confederation did not allow conquered peoples to become citizens.

True

Explanation:

As in Greece, in Rome the exercise of citizenship was linked with the ability to exercise political and civil rights. Roman citizenship was attributed only to free men, the conquered peoples were seen as a slave and for that reason, they did not have the right to be citizens. Citizens had the right: to be a subject of private law (jus civile); access to public offices and magistracies; participation of political assemblies; and tax advantages.

the correct answer is "ethnic heritage".

a person's ethnicity can influence a lot the way he/she votes.

in the united states, for example, black people tend to vote democratic. it happens because the society builds a strong division among people, and equals tend to mingle and support equals. black people's votes in a whole will most certaintly lean towards a candidate or a party which supports the fight against racism.
