Consider the following scenario:

Question

A scientist is analyzing one bird population. There is a large amount of variation in size in the
population. There are also predators that eat these birds. After collecting evidence on three types of
birds (small, medium, and large), the scientist discovers that the large birds are less likely to be killed
The only major genetic difference is the size of the birds. The colors and behaviors of the large birds
are the same as those of the small and medium birds.
Using reasoning skills, which is the most credible explanation for what is contributing to this higher
rate of survival?
(1 point)
O The large birds may be the smallest group in the population.
O The large birds may be the hardest for predators to see.
C
The large birds may be the largest group in the population.
The large birds may be the hardest for predators to attack.

Answer 1

The most credible explanation for the higher rate of survival of the large birds is:

The large birds may be the hardest for predators to attack.

This reasoning is based on the idea that larger size could provide an advantage in avoiding predation; larger birds may be tougher for predators to catch or may be able to defend themselves more effectively compared to smaller birds. The other options do not directly relate to the increased survival rates based on the given evidence about size and predation.
