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_Fo9bGnl):
How many times does the letter "o" appear in the text: "banks of"? Respond with an integer.

Question 1 (Question id: q_D3P0):
Calculate 1 / 1.

Question 2 (Question id: q_wYG4swrW):
Calculate ( ( -7 * -7 ) ).



Create a JSON object keyed by every question id except q_wYG4swrW.

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).
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_Fo9bGnl": {"answer": 1, "answer_type": "integer"}, "q_D3P0": {"answer": 1, "answer_type": "integer"}}}
