The diagram below shows that many generations of genetic changes led to the modern-day giraffe. Based on the diagram, it is plausible that the giraffe formed —

• longer legs to attack predators that approach.

• more spots to attract mates to produce offspring.

• a longer neck to reach food in higher areas when food was scarce.

• a narrower head to reach deep into trees and eat food that is hard to reach.

Over time, the food supply for birds on an isolated island has changed. The supply of insects, small tender seeds, and vegetation has shrunk. The supply of tough, large, hard seeds has remained unchanged. Over several generations, changes in genetic traits of birds' beaks have occurred. Which beak is most likely to improve the survival rate of the birds?
