Takumi works in his yard for 45 minutes each Saturday. He works in the morning, and he wears sunscreen and a hat each time he works in the yard.What does Takumi hope to reduce through his actions?

Sunscreen and a hat reduce Takumi’s exposure to ultraviolet radiation from the Sun. Reducing exposure lowers the likelihood of stochastic effects, such as DNA mutations that can contribute to cancer; it does not lessen the severity of an effect once it occurs. So the best choice is “the likelihood of stochastic effects, such as DNA mutations.”
