Renaissance Humanist culture was characterized by a shift away from medieval traditions and a renewed interest in classical Greek and Roman ideas. It placed a strong emphasis on the potential of human beings and their achievements.

Option 1 states that Renaissance Humanist culture slackened the control of religion over human life. This is true, as Humanism promoted a more secular worldview and encouraged individuals to focus on human reason and potential, rather than relying solely on religious authority.

Option 2 suggests that Humanism believed that human nature was many-sided. This is true as well, as Humanists believed that humans possessed a range of talents, abilities, and potential for growth and development.

Option 3 claims that Humanism was concerned with good manners. This is also true, as Humanists emphasized the importance of etiquette and manners as a way to demonstrate refinement and sophistication.

Option 4 states that Humanism criticized material wealth, power, and glory. This statement is NOT true. Renaissance Humanism celebrated worldly achievements, including material wealth, power, and glory. Humanists believed that these could be attained through the cultivation of individual talents and virtues.

In conclusion, Option 4 is the correct answer as it does not accurately represent the beliefs and values of Renaissance Humanist culture.
