Output JSON where all question ids are keys, omitting q_PfAV67s.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
