The work of James Hutton and Charles Lyell helped to a explain observations of twisted or bent rock layers. What was one of their conclusions?

A. Earth is extremely old, and Earth processes acted gradually to twist or bend rocks.
B. Earth is only a few thousand years old, and Earth formed with many twisted or bent rocks.
C. Earth is only a few thousand years old, and Earth processes acted much more rapidly in its early history.
D. Earth is extremely old, and Earth formed with many twisted or bent rocks.

Explanation:

(I've took this quiz lol)

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
