One of the key parts of natural selection, where organisms produce more offspring than can survive is called? Overproduction
Adaptation
Selection
Genetic Variation

when organisms produce more off spring than can survive is called overproduction

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.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
