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_xAPSq3):
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 1 snake, 1 shrimp, 1 lion, 3 flatworms, 4 spiders?
 Respond with an integer.

Question 1 (Question id: q_ctodT):
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 chickens, 2 crabs, 2 insects, 3 fireflys, 3 snakes?
 Respond with an integer.

Question 2 (Question id: q_40DjZab):
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: "so"

Question 3 (Question id: q_2GzJ):
Determine the value of f that satisfies: 10*f - 15 = 95 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 response to a question is a string, add a 'first_char' field containing its first character.
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_xAPSq3": {"answer": 46, "additional_answer_info": {"half_answer": 23, "double_answer": 92}}, "q_ctodT": {"answer": 56, "additional_answer_info": {"half_answer": 28, "double_answer": 112}}, "q_40DjZab": {"answer": "o", "first_char": "o", "original_string": "so"}, "q_2GzJ": {"answer": 11}}}
