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_jwNQ):
Calculate 9 / 1 + -4.

Question 1 (Question id: q_btGp2ZIv):
How many times does the letter "r" appear in the text: "paying copyright royalties"? Respond with an integer.



Return a JSON with each question id 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.
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.

{"ground_truth": {"q_jwNQ": {"answer": 5, "answer_type": "integer"}, "q_btGp2ZIv": {"answer": 2, "answer_type": "integer", "half_answer": 1}}}
