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_qiyTIl):
Solve for f: -4*f - 15 = -31 Respond with an integer.

Question 1 (Question id: q_FcM7F8t):
Find the value of p in the equation: 5*p + 15 = 65 Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
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).
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_qiyTIl": {"answer": 4, "additional_answer_info": {"half_answer": 2, "double_answer": 8}}, "q_FcM7F8t": {"answer": 10, "additional_answer_info": {"half_answer": 5, "double_answer": 20}}}}
