Output JSON where all question ids are keys, omitting q_48uOMZ, q_vUrkhQL.

The value for each key should be an object that contains the answer in the field 'answer'.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
Set 'num_questions_asked' to the count of questions originally displayed.
Record the answered-question count in the field 'num_questions_answered'.

Now provide the result JSON using the described format.
