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_lU3vALnB):
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 flatworm, 4 birds, 4 cows?
 Respond with an integer.

Question 1 (Question id: q_13VM5zo):
Calculate ( ( ( 8 + 7 ) ) - 2 ).



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

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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.

{"ground_truth": {"q_lU3vALnB": {"answer": 24, "half_answer": 12}, "q_13VM5zo": {"answer": 13}}}
