Consider the following scenario

Question

A scientist is analyzing, one bird population there’s 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 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 the higher rate of survival
A the large birds may be the largest group in the population
B the large birds may be the hardest for predators to attack
C the large birds may be the smallest group in the population
D the large birds may be the hardest for predators to see

Answer 1

The most credible explanation for the higher rate of survival among large birds would be that they are the hardest for predators to attack (option B). The fact that the only major genetic difference is size suggests that the larger birds may have physical characteristics that make them more difficult targets for predators. Their size could provide them with advantages such as stronger wings for faster flight, larger beaks for better defense, or other factors that make them less vulnerable to predation. The colors and behaviors of the large birds being the same as those of the small and medium birds indicates that it is primarily their size that is contributing to their higher rate of survival.
