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_VYoV):
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: "learning"

Question 1 (Question id: q_mvsV8mu):
Calculate ( 5 - -9 ).

Question 2 (Question id: q_Lxiz):
Calculate ( -3 * -1 ) / 1.



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.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_VYoV": {"answer": "g", "first_char": "g"}, "q_mvsV8mu": {"answer": 14, "half_answer": 7}, "q_Lxiz": {"answer": 3}}}
