Return a JSON with each question id (except for q_INvEFEOO, q_5NB0l, q_04Nw) 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.

Now provide the result JSON using the described format.
