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_SCQGt0XJ):
How many times does the letter "n" appear in the text: "electricity was known"? Respond with an integer.

Question 1 (Question id: q_Gsl2UNM):
Solve for b: 20*b + 2 = 342 Respond with an integer.



Create a JSON object keyed by every question id except q_Gsl2UNM.

Each key’s value must be an object holding an 'answer' field.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_SCQGt0XJ": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}}}
