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_hnoB2a):
How many times does the letter "s" appear in the text: "the novel writers"? Respond with an integer.

Question 1 (Question id: q_j6AzU):
Find the value of d in the equation: 216*d - 2 = 3670 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

Each key’s value must be an object holding an 'answer' field.
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_hnoB2a": {"answer": 1}, "q_j6AzU": {"answer": 17}}}
