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_B17WujC3):
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: "including"

Question 1 (Question id: q_azypA):
Calculate -8 * -2.

Question 2 (Question id: q_sFgQBb):
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: "others"



Your output must be a JSON mapping every question id to its answer info.

For every question id, supply an object whose 'answer' field stores the solution.
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 last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_B17WujC3": {"answer": "g", "original_string": "including"}, "q_azypA": {"answer": 16, "half_answer": 8}, "q_sFgQBb": {"answer": "s", "original_string": "others"}}}
