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_ohaLnJ):
Solve for a: 12*a + 17 = 89 Respond with an integer.

Question 1 (Question id: q_HawFAqQ7):
Find the value of d in the equation: 18*d + 11 = 263 Respond with an integer.

Question 2 (Question id: q_JxzSjXH):
How many times does the letter "l" appear in the text: "populations amounting"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

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).
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_ohaLnJ": {"answer": 6, "additional_answer_info": {"half_answer": 3, "double_answer": 12}}, "q_HawFAqQ7": {"answer": 14, "additional_answer_info": {"half_answer": 7, "double_answer": 28}}, "q_JxzSjXH": {"answer": 1}}}
