b. landfills
c. illegal dumping
d. industrial discharges

Septic systems is the BEST example of a non-point source of water

pollution.

a. septic systems

Explanation:

Residue from inappropriately oversaw building destinations, harvest and woods terrains, and disintegrating streambanks. Salt from water system practices and corrosive seepage from surrendered mines. Microbes and supplements from domesticated animals, pet squanders and broken septic frameworks. Residue from inappropriately oversaw building locales, harvest and woods grounds, and disintegrating streambanks.

Salt from water system practices and corrosive seepage from relinquished mines. Microscopic organisms and supplements from animals, pet squanders and flawed septic frameworks. So septic systems is the BEST case of a non-point wellspring of water contamination.

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.
