Final answer:
It is True that the 1991 amendments to the Civil Rights Act of 1964 made it unlawful to use different employment-related test cut-off scores based on race, reinforcing equal employment opportunity and merit-based practices.
Step-by-step explanation:
The statement that the 1991 amendments to the Civil Rights Act of 1964 made it unlawful for employers to use different cut-off scores for employment-related tests on the basis of race is True. This amendment is part of a series of changes designed to strengthen civil rights protections and provide for damages in cases of intentional employment discrimination. These adjustments to the Civil Rights Act aimed to prevent practices that had discriminatory impacts unless they were linked to job performance and were consistent with business necessity. By making it illegal to adjust scores, use different cut-off scores, or otherwise alter employee test results based on race, the 1991 amendments sought to enhance equal employment opportunities and reinforce a merit-based system free from racial bias.
