Evaluate
The opening claim is supported by the 2nd sentence, so it's fair to call the opening sentence a conclusion. But the opening sentence is also the support for the final claim, so the final claim is the main conclusion.
While we're usually suspicious of picking the last claim as the conclusion on Main Conclusion, it does happen 10-15% of the time, especially on lower difficulty questions. Since this is just a Q4, we can tell ourselves, "It's ok." :)
