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_5yPoWhjh):
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: "an"

Question 1 (Question id: q_vWGqOGy9):
How many times does the letter "h" appear in the text: "in machine"? Respond with an integer.

Question 2 (Question id: q_ly53NgA):
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 wasps, 2 lobsters, 4 sheeps, 3 ducks?
 Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field. 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.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_5yPoWhjh": {"answer": "n"}, "q_vWGqOGy9": {"answer": 1, "task_type": "letter_counting"}, "q_ly53NgA": {"answer": 66, "task_type": "leg_counting", "half_answer": 33}}}
