Questions: In America, self-actualization is the pinnacle need on Maslow's hierarchy. When studying cultures with a high need to avoid uncertainty, researchers found workers' pinnacle need to be - a. safety and security. b. socials c. physiological. d. esteem.

The answer is a. safety and security.

In cultures with a high need to avoid uncertainty, individuals often prioritize stability and predictability in their environment. This aligns with the need for safety and security, which includes job security, health, and safe working conditions. These needs are fundamental in reducing anxiety and stress associated with uncertainty.

While social needs, such as belonging and love, are important, they are typically not the pinnacle need in cultures that prioritize avoiding uncertainty. Social needs come after physiological and safety needs in Maslow's hierarchy.

Physiological needs are the most basic and essential for survival, such as food, water, and shelter. While crucial, they are not the pinnacle need in the context of avoiding uncertainty.

Esteem needs, which include self-respect, recognition, and achievement, are higher up in Maslow's hierarchy. However, in cultures with a high need to avoid uncertainty, safety and security needs take precedence over esteem needs.
