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_KPt63):
Calculate 2 * 7 - -9.

Question 1 (Question id: q_91zAYcf):
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: "money"



Create a JSON object keyed by every question id except q_KPt63.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Now provide the result JSON using the described format.

{"ground_truth": {"q_91zAYcf": {"answer": "y"}}}
