When dealing with stress, having to expend too much mental or physical energy over too long a period of time is known as: high demand high effort low control low reward?

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and 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.
