Accessing @TestVisible variables seems useful, but I think it might limit the flexibility of the test data.

Okay, I've got a strategy for this. I'll first eliminate any options that don't seem relevant, then focus on the remaining choices and try to determine the most likely answer based on my understanding of charge plans.

I can't recall if the FMC allows recovery after a purge, but I think I leaned towards option B being incorrect based on our discussions.

I remember something about pricing related to demand during peak times, but I'm struggling to remember the exact term. Incremental rates? Maybe?
