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_isTyNL9):
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 1 (Question id: q_K0MYw):
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 ducks, 4 giraffes, 4 flatworms, 2 butterflys, 1 horse?
 Respond with an integer.

Question 2 (Question id: q_6IUH):
How many times does the letter "o" appear in the text: "work b"? Respond with an integer.

Question 3 (Question id: q_fV9tcFR):
Calculate -2 * -4.

Question 4 (Question id: q_BGmriFo):
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 wasps, 2 humans, 3 crickets, 3 spiders, 3 grasshoppers?
 Respond with an integer.

Question 5 (Question id: q_NEq3Sncj):
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 6 (Question id: q_8qoF956):
Find the value of f in the equation: 19 - 16*f = -301 Respond with an integer.

Question 7 (Question id: q_b70NVP):
Calculate ( 7 - 2 ).



Return a JSON with each question id (except for q_8qoF956, q_BGmriFo, q_isTyNL9) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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.
