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_uuuXkQ):
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: "own"

Question 1 (Question id: q_zE5b):
Calculate 0 * -9.

Question 2 (Question id: q_yopNG1):
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 sea slugs, 4 butterflys, 3 tigers, 1 grasshopper?
 Respond with an integer.



Create a JSON object keyed by every question id except q_uuuXkQ.

Each key’s value must be an object holding an 'answer' field.
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.
If the response to a question is a string, add a 'first_char' field containing its first character.
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.

{"ground_truth": {"q_zE5b": {"answer": 0, "half_answer": 0}, "q_yopNG1": {"answer": 42, "half_answer": 21}}}
