C)Decreasing the census population size and making the sex ratio less balanced

D) Making the sex ratio more balanced and making mating more random (i. e., less local)

D

Explanation:

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.

the answer is a) a shiprock was formed by igneous process
