My recommendation would be to take this page, and any text with similar academic writing, locate a suitable receptacle and light it on fire. Your brain can only be damaged by attempting to follow this pseudo-intellectual gibberish.
As soon as this author stops talking about what power isn't, he becomes incoherent, spewing buzzwords in a seemingly random fashion.
As for your questions, if you know what "wistful" means I don't see how you see that in this text. I see no emotion in this text.
And there is no mention of "outward manifestations" so I don't see how that can be the correct answer.
This is not English, this is academic gobbledygook.
