What are the two key features of literacy test act?

The Literacy Act, more accurately described as literacy tests used in voter registration, didn't exist as a single, unified act. Instead, many states enacted their own laws requiring potential voters to pass literacy tests. Therefore, there's no single "Literacy Act" with two key features.

However, two key *characteristics* of these state-level literacy tests were:

1. Discriminatory Application and Design: While ostensibly designed to measure reading and writing ability, these tests were often administered in a biased and inconsistent manner, deliberately targeting African Americans and other minority groups. Tests were often harder for minority applicants, or the standards for passing were subjectively applied. This was a crucial element enabling the disenfranchisement of voters.

2. Used to Suppress the Vote: The stated purpose was to ensure only educated voters participated, but the real effect was to significantly reduce voter turnout among minority populations. The tests were a key tool of Jim Crow laws designed to circumvent the 15th Amendment's guarantee of voting rights regardless of race.
