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_ar3s2MG8):
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 3 chickens, 3 leechs, 3 shrimps?
 Respond with an integer.

Question 1 (Question id: q_r4Xl5z):
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: "teams"



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.
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 question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_ar3s2MG8": {"answer": 36, "half_answer": 18}, "q_r4Xl5z": {"answer": "s", "original_string": "teams"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_ar3s2MG8"]}}}
