Dry painting uses much more electricity than wet painting, and wet painting discharges many more volatile organic compounds than dry painting.

We can infer that...

1) If the use of electricity does not contribute to pollution, then dry painting is better for the environment than wet painting.

2) If the use of electricity contributes to pollution, then dry painting contributes to pollution.

-----------------------------------

please explain this problem. #2 is correct.

thanks.

Hey Ptraye,

#1 is about pollution, and nothing in the passage told us anything about that. The passage would have to tell you that "volatile organic compounds" are pollution, because we don't know that inherently.

#2 does this job correctly. It tells us that IF electricity causes pollution (Again, the passage never told us anything about what pollution does, so we need this to be told to us here), then dry painting causes pollution (because we know it uses electricity).

Hope that helps!
