Level 3 Q2
Which of the following is a function of
nucleic acids?
A. Speed up chemical reactions
B. Store and carry genetic information
C. Storage of energy
D. Performs the actual physical work within
the body

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.
