Answer 1

The type of environment that would tend to reduce genetic variation in a population because of evolution by natural selection is "grasslands that are undergoing severe drought."

Severe drought conditions can create strong selective pressure, favoring individuals that can survive with less water. As a result, individuals that do not possess traits suited for such conditions may not survive to reproduce, leading to a reduction in genetic variation within that population over time.
