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_rPW5z):
Calculate -3 * ( 9 * -5 ).

Question 1 (Question id: q_Rs3CUP):
How many times does the letter "k" appear in the text: "work required"? Respond with an integer.

Question 2 (Question id: q_DBBs):
Calculate 0 / 6 + 9.

Question 3 (Question id: q_Slmjlgb):
Find the value of h in the equation: 20 - 11*h = -90 Respond with an integer.

Question 4 (Question id: q_E0e401):
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: "and"

Question 5 (Question id: q_mTQ9ZdRQ):
Calculate 7 + -8 + 3.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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.
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.
