15. which idea is central to democracy in the united states?

payments were made after the 1940s.

in the 1980s, a commission held investigations and made recommendations.

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.
