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_EGhnd):
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_81MIyJb5):
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: "and"

Question 2 (Question id: q_dWkwbHfh):
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 snakes, 2 lobsters, 1 lion?
 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_EGhnd": {"answer": "s", "first_char": "s"}, "q_81MIyJb5": {"answer": "d", "first_char": "d"}, "q_dWkwbHfh": {"answer": 24, "half_answer": 12}}}
