Evaluate
On Role questions, at least 90% of the time, the last idea is a Supporting idea. On Role and Main Conclusion questions, they like to put the conclusion either right in the first sentence or as part of some Rebuttal sentiment.
The question stem is asking us about the second to last sentence, which was neither the Conclusion nor part of the Support.

The author is conceding an opposing point --
Goal
Look for something like "concedes an opposing point".
