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_kJC0):
Find the value of r in the equation: 40*r = 120 Respond with an integer.

Question 1 (Question id: q_8HdUv):
Find the value of r in the equation: 80*r + 272 = 1552 Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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).

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_kJC0": {"answer": 3}, "q_8HdUv": {"answer": 16, "additional_answer_info": {"half_answer": 8, "double_answer": 32}}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_kJC0", "q_8HdUv"]}}}
