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_kSfUZ):
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: "so"

Question 1 (Question id: q_0ER4):
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 1 cow, 4 sheeps, 4 butterflys?
 Respond with an integer.



Return a JSON with each question id (except for q_0ER4) as a key.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_kSfUZ": {"answer": "o", "answer_type": "string", "original_string": "so"}, "global_metadata": {"num_questions_asked": 2}}}
