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_jAnExhE):
Solve for o: o - 15 = 5 Respond with an integer.

Question 1 (Question id: q_cYS5diY):
Calculate 0 - ( -4 / 4 ).

Question 2 (Question id: q_hj9GZCh):
How many times does the letter "n" appear in the text: "electricity was known"? Respond with an integer.

Question 3 (Question id: q_WF5WZTh):
Calculate ( -4 / 1 + 4 ).

Question 4 (Question id: q_c1yPeBPP):
Calculate 5 - 1 * 0.



Create a JSON object keyed by every question id except q_c1yPeBPP.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
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).

Now provide the result JSON using the described format.
