Here is a set of basic questions producing integer or string outputs. Answer them and format the result precisely with the JSON instructions provided:

Question 0 (Question id: q_HYWP6):
Calculate ( ( 6 * 3 ) ).

Question 1 (Question id: q_wRRr):
Calculate ( ( 3 - -7 + -8 ) ).



Return a JSON with each question id (except for q_HYWP6) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_wRRr": {"answer": 2, "answer_type": "integer", "additional_answer_info": {"half_answer": 1, "double_answer": 4}}}}
