Question

read the excerpt from \womans rights to the suffrage.\
it was we, the people; not we, the white male citizens; nor yet we, the male citizens; but we, the whole people, who formed the union. and we formed it, not to give the blessings of liberty, but to secure them; not to the half of ourselves and the half of our descendants, but to the whole people - women as well as men. and it is a downright mockery to talk to women of their enjoyment of the blessings of liberty while they are denied the use of the only means of securing them provided by this democratic - republican government - the ballot.
which fact supports anthonys opinion that all adults should have the right to vote?

not to give the blessings of liberty...

Explanation:

Anthony's argument is centered around the idea that the Union was formed by "the whole people" (implying all adults, not just a subset like white males). This directly supports the notion that all adults should have voting rights as it emphasizes the inclusivity of the people who formed the nation. The other options either focus on the denial of means (which is a consequence but not a foundational fact supporting the right itself), or on mocking statements (which are critiques rather than factual supports for the right to vote).

Answer:

we, the whole people, who formed the Union.
