Where might you expect to find biased information?

judaism, christianity and islam, are all abrahamic religions and therefore have in common the hebrew idea of a single god which is the source of all morality. the idea of the covenant is only related to judaism, while dharma is a concept of indian religions and the four noble truths are basic principles of buddhism.

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.
