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_zv9cs):
How many times does the letter "j" appear in the text: "Project Gutenberg"? Respond with an integer.

Question 1 (Question id: q_cSsyiV):
Calculate ( 5 + 2 ).



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

For every question id, supply an object whose 'answer' field stores the solution.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_zv9cs": {"answer": 1}, "q_cSsyiV": {"answer": 7}}}
