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_ImTdu):
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: "and"

Question 1 (Question id: q_DYExLx):
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: "and"

Question 2 (Question id: q_scwGW):
Find the value of z in the equation: 20 - 4*z = -36 Respond with an integer.



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.
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_ImTdu": {"answer": "d", "original_string": "and"}, "q_DYExLx": {"answer": "d", "original_string": "and"}, "q_scwGW": {"answer": 14, "half_answer": 7}}}
