This excerpt from the Voting Rights Act from the 1965 supports the conclusion that previously it had been possible for states to block people from voting on account of

1. Race and creed
2. Language spoken
3. Gender and sexuality
4. Property and employment

The correct answer is 1. Race and creed.

The excerpt from the Voting Rights Act of 1965 aimed to eliminate any form of racial discrimination in voting practices. It prohibited the use of any voting qualifications, standards, or procedures that denied or abridged the right to vote on account of race or color. This legislation effectively eradicated the previous practices that had allowed states to block racial and ethnic minorities from exercising their voting rights.
