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_BOclSY):
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: "in"

Question 1 (Question id: q_SPmm):
Calculate ( -5 * -8 ).



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

Each key’s value must be an object holding an 'answer' field.
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.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_BOclSY": {"answer": "n", "first_char": "n", "original_string": "in"}, "q_SPmm": {"answer": 40, "half_answer": 20}}}
