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_1aXSDZE9):
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: "the"

Question 1 (Question id: q_nBulKI3u):
Find the value of m in the equation: 8*m + 13 = 53 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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_1aXSDZE9": {"answer": "e", "original_string": "the"}, "q_nBulKI3u": {"answer": 5}}}
