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_emcIBkU7):
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: "from"

Question 1 (Question id: q_dwgsQMl):
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 woodlouses, 4 spiders, 1 leech, 2 ants, 4 jellyfishs?
 Respond with an integer.

Question 2 (Question id: q_c46O):
Calculate 9 / 3.



Return a JSON with each question id (except for q_c46O) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.

{"ground_truth": {"q_emcIBkU7": {"answer": "m"}, "q_dwgsQMl": {"answer": 86, "additional_answer_info": {"half_answer": 43, "double_answer": 172}}}}
