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_U6lFLEM):
Solve for i: 12*i - 11 = 73 Respond with an integer.

Question 1 (Question id: q_1rs7l9e1):
How many times does the letter "i" appear in the text: "and again"? Respond with an integer.

Question 2 (Question id: q_0VzK):
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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
