Question

what is a direct cause of heat stroke?
too high body temperature
too heavy weights for lifting
too much unhealthy eating
too much exposure to snow

Explanation:

Heat stroke is a severe medical condition. It occurs when the body's temperature regulation system fails, and the body temperature rises to a dangerous level. Among the options, "too high body temperature" directly relates to the core mechanism of heat stroke. "Too heavy weights for lifting" is more related to musculoskeletal issues or physical exertion - related injuries not directly heat - stroke. "Too much unhealthy eating" can lead to various health problems like obesity, heart - related issues etc., but not directly heat stroke. "Too much exposure to snow" would lead to hypothermia (low body temperature) rather than heat stroke (high body temperature).

Answer:

too high body temperature
