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_azRo):
How many times does the letter "r" appear in the text: "other medium a"? Respond with an integer.

Question 1 (Question id: q_dAHE0CM):
Calculate 5 + 2.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
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_azRo": {"answer": 1, "answer_type": "integer"}, "q_dAHE0CM": {"answer": 7, "answer_type": "integer"}}}
