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_P9vhVOT):
Calculate -3 * -1 - -3.

Question 1 (Question id: q_dCHiq):
Solve for g: 2*g - 11 = 19 Respond with an integer.

Question 2 (Question id: q_ob68):
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: "why"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_P9vhVOT": {"answer": 6, "answer_type": "integer", "half_answer": 3}, "q_dCHiq": {"answer": 15, "answer_type": "integer"}, "q_ob68": {"answer": "y", "answer_type": "string", "original_string": "why"}}}
