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_qivq):
Find the value of r in the equation: 40*r = 120 Respond with an integer.

Question 1 (Question id: q_sDZ6U8Ik):
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: "of"

Question 2 (Question id: q_jjZpEj):
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: "people"

Question 3 (Question id: q_qqBT):
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 praying mantiss, 4 insects, 4 jellyfishs, 2 flatworms?
 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 integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.

{"ground_truth": {"q_qivq": {"answer": 3}, "q_sDZ6U8Ik": {"answer": "f"}, "q_jjZpEj": {"answer": "e"}, "q_qqBT": {"answer": 42, "additional_answer_info": {"half_answer": 21, "double_answer": 84}}, "global_metadata": {"num_questions_asked": 4}}}
