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_8TM7):
Determine the value of f that satisfies: 144*f - 10 = 2582 Respond with an integer.

Question 1 (Question id: q_hGl2BBkS):
How many times does the letter "g" appear in the text: "good Yes"? Respond with an integer.



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

For every question id, supply an object whose 'answer' field stores the solution.
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 string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_8TM7": {"answer": 18, "additional_answer_info": {"half_answer": 9, "double_answer": 36}}, "q_hGl2BBkS": {"answer": 1}}}
