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_wAiO):
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: "fight"

Question 1 (Question id: q_ib81):
Calculate ( ( 5 - 3 ) / 1 ).



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 integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.

{"ground_truth": {"q_wAiO": {"answer": "t"}, "q_ib81": {"answer": 2, "half_answer": 1}}}
