To Lazarus and Folkman, several factors determine a person's ability to cope with an event. Which of these is NOT one such factor?

A) Material resources, like money
B) Believing in positive outcomes
C) Believing one has some control
D) The magnitude of the life event

The magnitude of the life event is indeed one of the factors that determine a person's ability to cope, as it can influence the level of stress and the resources needed to deal with it. Therefore, the correct answer is D, which is the option that is NOT one of these factors. Material resources (A), believing in positive outcomes (B), and believing one has some control (C) are all factors that can affect coping abilities according to Lazarus and Folkman's theory.
