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_a4BAmZcv):
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, 1 insect, 1 chicken, 1 jellyfish, 2 sheeps?
 Respond with an integer.

Question 1 (Question id: q_fWsbzr):
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_Ax2bTvc):
Determine the value of a that satisfies: 15 - 4*a = -21 Respond with an integer.

Question 3 (Question id: q_NSP81gU):
Calculate ( ( 8 - -2 ) * 3 ).



Create a JSON object keyed by every question id except q_a4BAmZcv.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
• num_questions_answered – number you actually answered.

Now provide the result JSON using the described format.

{"ground_truth": {"q_fWsbzr": {"answer": "d", "answer_type": "string", "original_string": "and"}, "q_Ax2bTvc": {"answer": 9, "answer_type": "integer"}, "q_NSP81gU": {"answer": 30, "answer_type": "integer", "additional_answer_info": {"half_answer": 15, "double_answer": 60}}, "global_metadata": {"num_questions_asked": 4, "num_questions_answered": 3}}}
