Question 3 (Question id: q_k4mxFo):
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: "a"



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'.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.

Now provide the result JSON using the described format.

{"ground_truth": {"q_2r6ff": {"answer": 5}, "q_5REK": {"answer": 60, "half_answer": 30}, "q_15CPBbQO": {"answer": "s"}, "q_k4mxFo": {"answer": "a"}}}
