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_M0ISU):
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: "people"

Question 1 (Question id: q_AxdTYVI):
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 jellyfishs, 4 starfishs, 2 flatworms?
 Respond with an integer.

Question 2 (Question id: q_HuO6):
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 elephants, 4 ants, 1 spider?
 Respond with an integer.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_M0ISU": {"answer": "e", "original_string": "people"}, "q_AxdTYVI": {"answer": 20, "task_type": "leg_counting", "half_answer": 10}, "q_HuO6": {"answer": 40, "task_type": "leg_counting", "half_answer": 20}}}
