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_rtyC8):
Determine the value of i that satisfies: 4*i - 1 = 47 Respond with an integer.

Question 1 (Question id: q_xBcnm):
How many times does the letter "b" appear in the text: "being here I"? Respond with an integer.

Question 2 (Question id: q_s2jEKZc):
How many times does the letter "u" appear in the text: "live continually in"? Respond with an integer.

Question 3 (Question id: q_QLMIiQGU):
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: "rainforests"

Question 4 (Question id: q_NhDj):
Solve for f: 9*f + 2 = 146 Respond with an integer.

Question 5 (Question id: q_UyIsdL):
Calculate ( -4 * -9 ).

Question 6 (Question id: q_I80ctrG):
How many times does the letter "a" appear in the text: "as to the"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

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 response to a question is a string, add a 'first_char' field containing its first character.
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.
