PLEASE HELP How can cooling of melted rocks produce different types of igneous rocks?

The cooling rate of magma can change the rocks' chemical composition.
The cooling rate can change the density of igneous rocks.
The texture of igneous rocks depends on the rate of cooling of magma or lava.
The cooling rate can affect the size of igneous rocks.

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

cuz he's blad

explanation:

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.
