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_0LdAFmxP):
How many times does the letter "r" appear in the text: "hundreds of"? Respond with an integer.

Question 1 (Question id: q_Vj4j06CB):
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: "system"

Question 2 (Question id: q_hgAfr):
Calculate 6 / 6.



Output JSON where all question ids are keys, omitting q_0LdAFmxP.

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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_hgAfr": {"answer": 1, "answer_type": "integer"}, "q_Vj4j06CB": {"answer": "m", "answer_type": "string"}}}
