In the article about Dismaland there is a paragraph saying:
Inside the walls of a derelict seaside swimming resort in Weston-super-Mare, UK, mysterious construction over the last month—including a dingy looking Disney-like castle and a gargantuan rainbow-colored pinwheel tangled in plastic—suggested something big was afoot. Suspicion and anticipation surrounding the unusual activity attributed to fabled artist and provocateur Banksy has reached a Willy Wonka-esque fervor. Well, if Banksy’s your bag, continue fervoring. If not, there’s more than a few reasons to continue reading.
I'm not sure if I understand the meaning of this bold sentence correctly. I tried to divide it into two sentences:
The unusual activity (was) attributed to fabled artist and provocateur Banksy. Suspicion and anticipation has reached a Willy Wonka-esque fervor.
But now I don't know - is it possible to use 'has' as a predicate for two things (suspicion and anticipation)?
