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_l9FfUNl):
Solve for w: 91*w = 1547 Respond with an integer.

Question 1 (Question id: q_zcK7SAZ):
Find the value of o in the equation: 31 - o = 22 Respond with an integer.



Return a JSON with each question id (except for q_zcK7SAZ) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_l9FfUNl": {"answer": 17, "answer_type": "integer"}}}
