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_SP9Gx):
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: "a"

Question 1 (Question id: q_fwvl4):
How many times does the letter "a" appear in the text: "at her"? Respond with an integer.

Question 2 (Question id: q_OJZGuDjL):
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: "are"

Question 3 (Question id: q_sWa6Q):
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 wasp, 3 birds, 2 grasshoppers?
 Respond with an integer.

Question 4 (Question id: q_YWlN):
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 2 crabs, 2 fireflys, 1 scorpion, 2 tigers, 3 starfishs?
 Respond with an integer.

Question 5 (Question id: q_RZuBHMi):
Calculate 4 + 2 - 3.

Question 6 (Question id: q_RxrB):
Calculate 0 * 1.

Question 7 (Question id: q_HMcf):
How many times does the letter "r" appear in the text: "requests of"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_RZuBHMi, q_OJZGuDjL.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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.
