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_77lv30LT):
Calculate 4 / 1.

Question 1 (Question id: q_CCNKFoW):
Calculate 5 - -6 - -4.

Question 2 (Question id: q_W8rCn):
Calculate 6 + 5.

Question 3 (Question id: q_ByEox):
Calculate 3 + 8 - -2.

Question 4 (Question id: q_eLsMTddd):
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: "there"

Question 5 (Question id: q_AoEp2XT):
Solve for f: 13 - 5*f = -22 Respond with an integer.



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

For every question id, supply an object whose 'answer' field stores the solution.
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).
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.
