   Draining the lake would not cause the region's tourism economy

   All we know about drained lake is "ruled out". Maybe it would, maybe it wouldn't cause the tourism economy to suffer. Common sense probably suggests that if the tainted water hurt tourism four years ago, the tourists must be kinda interested in coming to use the water. So a drained lake likely would hurt tourism.

   Four years ago was the only time that poison was used against the pike

   This is the ol' Only One Mentioned = Only One trap. Just because we only talked about poisoning the lake four years ago, that doesn't mean four years ago is the only time we poisoned the lake. (I don't mean to brag, but .... we've poisoned that lake a ton!)

   Why this is right

   Given that the problem of "how do we get the pike out of this lake, before they escape into the river system" still exists, we can assume that the poison didn't do the job in eradicating the pike. If we were thinking, "maybe the poison rid the lake of the pike 4 years ago, but then 2 years ago the pike was reintroduced." Sure. You're right. That's possible. But it's not probable. It's pretty rare for a fish species to completely vanish from an ecosystem, but then come back at a problematic level just a couple years later. And check the question stem: it's Most Supported, so it doesn't have to be perfect. This synthesizes ideas (the way correct answers are supposed to) by combining "we're still mulling over solutions" with "4 years ago, we tried poison".

   Skill tested: Most Supported · how this choice captures the argument's function is the move to repeat next time.

   Salmon and trout populations in the Lake Davis area are essential to

   We can infer that salmon and trout populations have some value, since we are mulling over solutions in an attempt to save them. But we don't have any evidence that they're essential to the local economy.
