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_7sdMYnDl):
How many times does the letter "n" appear in the text: "individual Project"? Respond with an integer.

Question 1 (Question id: q_vPAL):
Calculate -9 * ( -6 - 1 ).

Question 2 (Question id: q_zJQmAL):
Find the value of b in the equation: 4*b + 7 = 27 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.
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.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_7sdMYnDl": {"answer": 1}, "q_vPAL": {"answer": 63}, "q_zJQmAL": {"answer": 5}}}
