a: saving money n time
b: conserving water
c: protecting the environment against harmful toxins
d: causing unnecessary air pollution.

B: conserving water

Explanation:

By using water at the lowest possible level for the load, Paul is conserving water, which is just the amount necessary for his clothes.  With this measure he might save money (as he will be paying less for the water) but not time. This decision won't make difference concernirg the environment protection nor in causing unncessary air polution.

depends on your school

when i was in high school i took ap biology my senior year and it was the hardest one for me because my teacher finished the material within the first month of school and then went on to doing advanced college level it was horrible. but at a nearby school ap biology was one of the easier aps. also, it depends on what you are interested i like math a lot so ap calculus was easier for me than most but i hate history so ap us government was harder for me than most.
