Return a JSON with each question id (except for q_Rn7Shvsf, q_HjRUa8) as a key.

Each key’s value must be an object holding an 'answer' field.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
