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_zeUAB):
Find the value of c in the equation: 10 - 16*c = -150 Respond with an integer.

Question 1 (Question id: q_9zknsT5):
How many times does the letter "n" appear in the text: "General Terms"? Respond with an integer.

Question 2 (Question id: q_HlVTqbV):
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 snakes, 3 sheeps, 4 wasps, 4 jellyfishs?
 Respond with an integer.

Question 3 (Question id: q_NcMy70Z):
Calculate -4 + 0 + 9.



Return a JSON with each question id (except for q_9zknsT5) as a key.

Each key’s value must be an object holding an 'answer' field. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
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).
For string answers, include 'first_char' with the answer’s initial letter.
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.
