further explanation

I get how c is right from the previous explanation listed here. however, I eliminated it because I don't see how it is guaranteed. Example, let's say the poison did work those years back and someone reintroduced the pike back into the lake years later. Not sure if I'm being clear enough to make sense but just trying to figure out how to avoid thinking outside the box like in my example.

I think you're right: it's completely possible that the poison was successful for a time, and the pike were able to return later. First, I would argue then that this strategy was not fully successful. The poison may have worked, but since there are still pike, the strategy was not fully successful. This is a bit petty, and I don't like this argument at all. I think a stronger explanation is that for most strongly supported questions, it's ok if there's 1 percent of doubt. For a true must be true the right answer has to be definitely proven. For most strongly supported, 99 percent is ok. It's not an issue if there's an unlikely but not impossible scenario where the answer choice is not true, because it is still very strongly supported by the passage.
