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_4p0cfo):
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: "might"

Question 1 (Question id: q_uwvDpB):
Find the value of i in the equation: 6*i + 28 = 88 Respond with an integer.

Question 2 (Question id: q_XpCWb):
Calculate -7 * -4 + -7.

Question 3 (Question id: q_7EGy):

Question 5 (Question id: q_uIrP):

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'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer 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).
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
