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_1QuCdN3K):
Find the value of o in the equation: 31 - o = 22 Respond with an integer.

Question 1 (Question id: q_yA7twrK):
How many times does the letter "e" appear in the text: "agreement There are"? Respond with an integer.

Question 2 (Question id: q_Cahyq):
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: "is"



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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.
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_1QuCdN3K": {"answer": 9}, "q_yA7twrK": {"answer": 6, "additional_answer_info": {"half_answer": 3, "double_answer": 12}}, "q_Cahyq": {"answer": "s", "first_char": "s", "original_string": "is"}}}
