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_vKCsB9):
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: "includes"

Question 1 (Question id: q_a9tKFW):
Determine the value of m that satisfies: 13*m - 11 = 106 Respond with an integer.



Output JSON where all question ids are keys, omitting q_vKCsB9.

Each key’s value must be an object holding an 'answer' field.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_a9tKFW": {"answer": 9}}}
