Anybody want to help on a school project?

I'll help with your survey,

Quest#1 = ans.#3, a lot
Quest#2 = ans.#1, the effects of pollution from human activities
Quest#3 = ans.#2, generally correct
Quest#4 = ans.#3, high, priority for the president and congress
Quest#5 = ans.#4, a great deal
Quest#6 = ans.#2, worse

Good luck, and you're welcome.
Paul
