Using evidence from the diagram, which adaptation has allowed finches to survive in their habitat?

I would assume, from the diagram, it's their beaks.

Explanation:

Finches are largely different and reside in different areas, but the part of them that has changed is their beaks because each species eats a different type of food.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
