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_u87WE9):
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 1 (Question id: q_qYGC):
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 leechs, 2 lions, 4 sea slugs, 1 bee?
 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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.

{"ground_truth": {"q_u87WE9": {"answer": "d"}, "q_qYGC": {"answer": 14, "half_answer": 7}}}
