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_aHqi):
Find the value of b in the equation: 6 - 2*b = -30 Respond with an integer.

Question 1 (Question id: q_eVJAUuv):
How many times does the letter "i" appear in the text: "the first was"? Respond with an integer.

Question 2 (Question id: q_dgB1a):
Calculate -3 + 9.

Question 3 (Question id: q_iUXj):
Calculate -1 - -9.

Question 4 (Question id: q_UajA2U5):
Find the value of g in the equation: 70*g - 6 = 1254 Respond with an integer.



Output JSON where all question ids are keys, omitting q_eVJAUuv, q_iUXj.

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).
For string answers, include 'first_char' with the answer’s initial letter.
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.
