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_Rvufw):
Calculate 0 - -2.

Question 1 (Question id: q_X2uaN5q):
Find the value of h in the equation: 4*h - 6 = 70 Respond with an integer.

Question 2 (Question id: q_6gsOuAdV):
How many times does the letter "n" appear in the text: "creating the Project"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

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 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_Rvufw": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "q_X2uaN5q": {"answer": 19}, "q_6gsOuAdV": {"answer": 1}}}
