Question

liberals believed that the government had a duty to
keep taxes as low as
possible.
ensure that no one lived in
poverty.
balance the budget.

Explanation:

To determine the correct option, we recall the beliefs of liberals (in the context of political ideology, which falls under Social Science - Politics subfield). Liberals typically advocate for government intervention to address social issues like poverty, aiming to ensure social welfare. "Keep taxes as low as possible" is more aligned with conservative or libertarian views, and "balance the budget" is a more general fiscal responsibility view not specific to liberal ideology. So the correct option is the one stating "ensure that no one lived in poverty."

Answer:

The middle option: ensure that no one lived in poverty.
