Evaluate
We know when we read the argument on Main Conclusion or Role that we're most likely going to see an upside-down argument, where the conclusion comes earlier and the support comes later. In particular, we listen for First Sentence opinions from the author (usually those would be the Main Conclusion) or early Attributions (usually the conclusion would be a pivot/rebuttal from that idea).

So we'll need to be more nuanced, like, .
