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_hyHl):
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 cows, 2 ducks, 3 giraffes, 4 horses, 3 humans?
 Respond with an integer.

Question 1 (Question id: q_xTDg7Td):
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: "a"

Question 2 (Question id: q_PHOi):
Determine the value of k that satisfies: 30*k + 45 = 165 Respond with an integer.

Question 3 (Question id: q_57Wo):
Solve for g: 4*g + 10 = 38 Respond with an integer.



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

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 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.

{"ground_truth": {"q_hyHl": {"answer": 50, "additional_answer_info": {"half_answer": 25, "double_answer": 100}}, "q_xTDg7Td": {"answer": "a", "original_string": "a"}, "q_PHOi": {"answer": 4, "additional_answer_info": {"half_answer": 2, "double_answer": 8}}, "q_57Wo": {"answer": 7}}}
