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_gNRu):
Calculate ( ( ( -9 * -8 ) ) ).

Question 1 (Question id: q_w1BIxH):
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: "story"

Question 2 (Question id: q_wzvwMP):
Calculate ( -9 + 6 ) + 9.

Question 3 (Question id: q_OnvbP):
How many times does the letter "a" appear in the text: "bomb among them"? Respond with an integer.

Question 4 (Question id: q_Hs0Kkh):
Find the value of z in the equation: 20 - 4*z = -36 Respond with an integer.



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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.
