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_IbhZ21G):
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: "is"

Question 1 (Question id: q_2PeK):
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: "way"

Question 2 (Question id: q_DW7sU8t):
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 grasshoppers, 2 insects, 2 cats?
 Respond with an integer.

Question 3 (Question id: q_Xle8):
Calculate 9 / 3.



Produce a JSON object whose top-level keys are the question ids.

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.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_IbhZ21G": {"answer": "s", "first_char": "s"}, "q_2PeK": {"answer": "y", "first_char": "y"}, "q_DW7sU8t": {"answer": 44, "half_answer": 22}, "q_Xle8": {"answer": 3}}}
