Which word describes a level of intensity that is much more than usual?

The term that best describes a level of intensity that is much more than usual is "extreme." This word conveys a sense of exceeding normal limits or experiencing something that goes far beyond the typical or moderate levels. In various contexts, such as weather, sports, or emotional states, "extreme" indicates conditions, activities, or feelings that are intense or severe relative to what is typically experienced.

In contrast, the other choices such as "moderate," "minimal," and "average," all suggest standard or limited levels of intensity. "Moderate" refers to a balanced or average amount, while "minimal" indicates the least possible amount, and "average" implies a common or typical state. These terms do not capture the heightened intensity that "extreme" signifies, hence reinforcing why "extreme" is the appropriate choice in this context.
