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_D7T9):
Calculate ( -6 * -9 ) - -2.

Question 1 (Question id: q_UuAakry):
Find the value of z in the equation: 20 - 4*z = -36 Respond with an integer.

Question 2 (Question id: q_MG3y8Y6):
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: "can"

Question 3 (Question id: q_igjDf):
How many times does the letter "r" appear in the text: "they breathe an"? Respond with an integer.

Question 4 (Question id: q_EuM0wT):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 3 crabs, 3 cockroachs, 3 spiders, 2 lobsters, 4 flatworms?
 Respond with an integer.

Question 5 (Question id: q_i9UeT):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 cockroachs, 4 cows, 3 scorpions, 4 jellyfishs, 3 fireflys?
 Respond with an integer.

Question 6 (Question id: q_9gENc):
How many times does the letter "r" appear in the text: "and were supplied"? Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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.
