Take the following as truth: you think well nobody's using the bathroom farther up stream so it's got to be all right so we were doing things like uh you know we all had our little collapsible cups and we were going up to where the water was coming over rocks and all that and we'd just kind of stick our cups in there and drink and then we were there for five or six days and and and it was neat you know we saw deer and uh
Then the following statement: "You think no one is going to the bathroom upstream so it should be safe to drink and so far we've been right." is true, false, or inconclusive?
Answer: Inconclusive
