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_4y3RhQ):
Find the value of w in the equation: 15*w + 14 = 209 Respond with an integer.

Question 1 (Question id: q_x4g9):
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 4 fireflys, 4 cockroachs, 2 dogs, 2 shrimps, 1 leech?
 Respond with an integer.

Question 2 (Question id: q_XZlxkYR):
Determine the value of h that satisfies: h - 14 = -2 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

Each key’s value must be an object holding an 'answer' field.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_4y3RhQ": {"answer": 13}, "q_x4g9": {"answer": 76, "additional_answer_info": {"half_answer": 38, "double_answer": 152}}, "q_XZlxkYR": {"answer": 12, "additional_answer_info": {"half_answer": 6, "double_answer": 24}}}}
