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_lvTgMNb):
Determine the value of f that satisfies: 14*f + 31 = 115 Respond with an integer.

Question 1 (Question id: q_LlSw0tI4):
Calculate 9 / 9 + 4.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_lvTgMNb": {"answer": 6, "answer_type": "integer", "additional_answer_info": {"half_answer": 3, "double_answer": 12}}, "q_LlSw0tI4": {"answer": 5, "answer_type": "integer"}}}
