The capstone of this round uses unusual abbreviations. We notice that the clue is repeated with multiple layers, ad infinitum. This hints at the gimmick: recursive acronyms, which refer to themselves. A list of recursive acronyms can be found on Wikipedia.
To parse the clues, we can treat everything inside a pair of parentheses as equal to the answer itself, which resolves to a single letter. This letter is then used to form part of the final answer. For example, we can rewrite the third clue as “Hofstadter’s deity (<answer>) overdosed”, which suggests that the answer is ?OD, or GOD, with the parenthesized phrase extracting to the letter G.
