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_fzow5LH):
Find the value of d in the equation: 18*d + 11 = 263 Respond with an integer.

Question 1 (Question id: q_vV9y):
Solve for r: 18*r + 3 = 57 Respond with an integer.



Return a JSON with each question id (except for q_vV9y) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
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).

Now provide the result JSON using the described format.

{"ground_truth": {"q_fzow5LH": {"answer": 14, "additional_answer_info": {"half_answer": 7, "double_answer": 28}}}}
