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_3E3PCtN):
Determine the value of l that satisfies: 19*l + 31 = 50 Respond with an integer.

Question 1 (Question id: q_Piip):
Determine the value of q that satisfies: 171*q = 2394 Respond with an integer.

Question 2 (Question id: q_XN80uvR7):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "living"

Question 3 (Question id: q_SgHi):
Determine the value of b that satisfies: 16*b + 18 = 146 Respond with an integer.

Question 4 (Question id: q_9bu2):
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 horses, 4 wasps, 3 crickets, 4 bees?
 Respond with an integer.



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

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.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_3E3PCtN": {"answer": 1}, "q_Piip": {"answer": 14, "additional_answer_info": {"half_answer": 7, "double_answer": 28}}, "q_XN80uvR7": {"answer": "g", "first_char": "g"}, "q_SgHi": {"answer": 8, "additional_answer_info": {"half_answer": 4, "double_answer": 16}}, "q_9bu2": {"answer": 74, "additional_answer_info": {"half_answer": 37, "double_answer": 148}}}}
