Answer 1

The correct statement is: Birds with long legs were selected for.

When the distribution curve for leg length shifts to the right, it indicates that the average leg length in the population has increased. This usually suggests that longer-legged birds have a selective advantage in the population due to the disturbance, likely allowing them to survive and reproduce more successfully than those with shorter legs.
