So I don't have to worry about whether or not there were assumptions that we should also be treating as true, because this argument was actually a valid argument. The conclusion just summarizes our conditional chain. If we're going to find something that must be false, then we have a big old conditional chain, then we should again be reminding ourselves, that's going to sound like you are the trigger, which are not the outcome. But the question stem was actually even more specific. It said, what would we know about teachers who have enabled students to make their own decisions? So that's our third link.
