In the gel example, Opus 5 answers five because it fails to recognize the band at the twenty bar; the speaker says the example cannot be run in Opus 5.5 because of a security guard.

“Yeah. But, uh, so worth noting, um, you can't run this in Opus 5.5 because of the security guard, so it's run on Opus 5. Um, but, uh, to your point, yeah, it answers five because it basically doesn't see that, um, band at lane-- on the, the twenty bar to be an actual band.”
