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_iZs1iQPz):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "sports"

Question 1 (Question id: q_FXWL1D):
Calculate -8 * ( ( -1 - 5 ) ).



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_iZs1iQPz": {"answer": "s", "answer_type": "string"}, "q_FXWL1D": {"answer": 48, "answer_type": "integer", "half_answer": 24}}}
