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_x3Z3I):
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: "that"

Question 1 (Question id: q_nHkobA):
How many times does the letter "o" appear in the text: "is unprotected"? Respond with an integer.

Question 2 (Question id: q_eiw4q72):
How many times does the letter "b" appear in the text: "distribute this"? Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_x3Z3I": {"answer": "t", "answer_type": "string", "original_string": "that"}, "q_nHkobA": {"answer": 1, "answer_type": "integer"}, "q_eiw4q72": {"answer": 1, "answer_type": "integer"}}}
