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_7cvB6iz):
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 cockroachs, 4 grasshoppers, 2 ants?
 Respond with an integer.

Question 1 (Question id: q_GKCh):
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 butterfly, 4 jellyfishs, 2 beetles, 1 ant?
 Respond with an integer.

Question 2 (Question id: q_r8nBtVY):
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: "others"

Question 3 (Question id: q_brMmaR6):
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: "others"



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.
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.
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_7cvB6iz": {"answer": 48, "half_answer": 24}, "q_GKCh": {"answer": 24, "half_answer": 12}, "q_r8nBtVY": {"answer": "s", "original_string": "others"}, "q_brMmaR6": {"answer": "s", "original_string": "others"}}}
