Support/Contrast Problem

The _________ of the royal court afforded authorities sufficient _________ for interference. Isabella, the new queen, _________ and depraved, engendered much instability.
What would be the support/contrast idea for the first and second blank?

What do you think?

I was thinking if “afforded” would be the support idea for first blank and “sufficient” would be the support idea for the second blank. But whenever I try to put those into the blanks, I’m getting “wrong answers” popup. So, I’m a little bit confused.

Which blank do you solve first here?

Third one.

So when the RHS is filled in and we know that “the queen engendered much instability” we can support that idea to fill in B2 right? So maybe the full stop?
