Hopefully someone will jump in who knows the specifics here – regrettably, we're not really a official support channel for the MVAs. Jason will have gotten this so we'll see if he can maybe chime in – he may have an idea what you're after. But I'm not sure he actually wrote or has even seen the quiz questions.
Offhand, just reading this out of context, I'd agree with your B&C answer, although "DOT Source mode" is certainly not a way I've ever heard dot-sourcing referred to! Makes me curious who DID write the quiz questions.
