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_hKkrh):
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: "is"

Question 1 (Question id: q_OoRsw75):
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: "long"



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'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_hKkrh": {"answer": "s", "first_char": "s"}, "q_OoRsw75": {"answer": "g", "first_char": "g"}}}
