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_CZzb):
Calculate 6 - 4 + -1.

Question 1 (Question id: q_HnJr):
Solve for w: 8 - 18*w = -208 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_CZzb": {"answer": 1, "answer_type": "integer"}, "q_HnJr": {"answer": 12, "answer_type": "integer", "half_answer": 6}}}
