Return a JSON with each question id (except for q_JiLcGsM, q_wzCe, q_Kb4tN) as a key.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
Record the answered-question count in the field 'num_questions_answered'.

Now provide the result JSON using the described format.
