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_iSukiSR):
Solve for r: 11*r + 187 = 319 Respond with an integer.

Question 1 (Question id: q_kkKXOQj):
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: "it"



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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.

{"ground_truth": {"q_iSukiSR": {"answer": 12, "additional_answer_info": {"half_answer": 6, "double_answer": 24}}, "q_kkKXOQj": {"answer": "t"}}}
