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_LgLtj):
Solve for r: 4*r - 9 = 19 Respond with an integer.

Question 1 (Question id: q_tW3M):
How many times does the letter "n" appear in the text: "it is near"? Respond with an integer.

Question 2 (Question id: q_NgFvKvL):
Calculate ( 5 + -2 ) + -2.

Question 3 (Question id: q_hxeCaX):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 3 butterflys, 3 starfishs, 3 lions, 2 jellyfishs?
 Respond with an integer.

Question 4 (Question id: q_jLeaDm):
Solve for b: 20*b + 2 = 342 Respond with an integer.



Output JSON where all question ids are keys, omitting q_jLeaDm, q_tW3M.

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.

Now provide the result JSON using the described format.
