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_8vBIdfdU):
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: "things"

Question 1 (Question id: q_LmU4Po):
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 1 spider, 3 praying mantiss, 3 snakes, 4 crickets, 2 insects?
 Respond with an integer.

Question 2 (Question id: q_8zst):
Calculate 9 + 7.

Question 3 (Question id: q_3j2DMM):
Calculate 8 - 6.

Question 4 (Question id: q_qbGD):
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 1 giraffe, 4 sea slugs, 3 cows?
 Respond with an integer.

Question 5 (Question id: q_kEvTz):
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: "train"

Question 6 (Question id: q_XII8R0):
Determine the value of i that satisfies: 16*i + 20 = 84 Respond with an integer.

Question 7 (Question id: q_FiJIqA):
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: "physics"

Question 8 (Question id: q_hjm4Qzwz):
Calculate -8 * -3.



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.
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.
