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_zyJH):
Calculate ( ( -5 - -9 ) / 1 ).

Question 1 (Question id: q_7P75n):
Calculate 5 + 4.

Question 2 (Question id: q_aJYprVa):
Determine the value of b that satisfies: 95*b + 1900 = 2090 Respond with an integer.

Question 3 (Question id: q_4hR3kq):
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 2 jellyfishs, 3 scorpions, 1 horse, 4 snakes, 1 cockroach?
 Respond with an integer.

Question 4 (Question id: q_7KpLnj):
How many times does the letter "n" appear in the text: "General Terms"? Respond with an integer.



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

The value for each key should be an object that contains the answer in the field 'answer'.
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.

Now provide the result JSON using the described format.
