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_aJXBOqQ):
Solve for j: 360*j + 13 = 3613 Respond with an integer.

Question 1 (Question id: q_gQvy):
Calculate -2 + 5.

Question 2 (Question id: q_GOOR4EDx):
Calculate 7 * 7.



Return a JSON with each question id as a key.

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).
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_aJXBOqQ": {"answer": 10, "additional_answer_info": {"half_answer": 5, "double_answer": 20}}, "q_gQvy": {"answer": 3}, "q_GOOR4EDx": {"answer": 49}}}
