What was the answer to that? I put D because I thought the town would put nutrients into the water and increase the biochemical demand and lower dissolved oxygen, and the quarry would increase pH since limestone is alkaline. But someone else reckons it is A. What does everyone else think.

i think i did D too, the town would increase BOD cos of sewage or something, the limestone would make it basic i think... anyways im pretty sure that's the right one, makes sense too cos the DO decreased from the source

I said D because
-Oxygen content is high at the source.
-pH would increse at the limestone quarry
-pH would decrease with wastes at the town and Oxygen demand increase from algea and such.
At least that my explaination, maybe wrong.

lol i dont think i put D. i practically ran out of the exam. i didnt go thru my paper. not even MC. normally i go back through it and mark on the paper what i put so i can compare to people on here. But all my answers were complete guesses so i doubt what i put was right
