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_QYFHJ):
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: "air"

Question 1 (Question id: q_dTCYuk):
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 deers, 4 woodlouses, 1 dog, 1 lobster?
 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.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_QYFHJ": {"answer": "r", "first_char": "r", "original_string": "air"}, "q_dTCYuk": {"answer": 78, "half_answer": 39}}}
