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_jIquRc):
Calculate -9 + 4 + 5.

Question 1 (Question id: q_T7Y0oGlZ):
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: "to"

Question 2 (Question id: q_WQgT):
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: "and"



Produce a JSON object whose top-level keys are the question ids.

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 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_jIquRc": {"answer": 0, "additional_answer_info": {"half_answer": 0, "double_answer": 0}}, "q_T7Y0oGlZ": {"answer": "o", "original_string": "to"}, "q_WQgT": {"answer": "d", "original_string": "and"}}}
