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_tOdvG):
Calculate ( 4 + 2 ).

Question 1 (Question id: q_yikp3Q):
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: "one"



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

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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_tOdvG": {"answer": 6, "half_answer": 3}, "q_yikp3Q": {"answer": "e", "original_string": "one"}}}
