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_xIqe5):
How many times does the letter "i" appear in the text: "I am"? Respond with an integer.

Question 1 (Question id: q_VwkhS):
How many times does the letter "e" appear in the text: "of the four"? Respond with an integer.

Question 2 (Question id: q_p43Kf):
Calculate 9 + 2 * 5.

Question 3 (Question id: q_lJNz8P5w):
Determine the value of d that satisfies: 12*d + 15 = 111 Respond with an integer.



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'.
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.
