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_KWi9E0g):
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 crabs, 1 cow, 2 fireflys, 3 grasshoppers, 4 scorpions?
 Respond with an integer.

Question 1 (Question id: q_QVrAZw):
Calculate -5 * -3 - -2.

Question 2 (Question id: q_vpoC):
How many times does the letter "e" appear in the text: "s EIN or"? Respond with an integer.

Question 3 (Question id: q_q0T1j):
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: "of"



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

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, also add the field 'half_answer' to the object which contains the answer integer divided by two.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_KWi9E0g": {"answer": 86, "half_answer": 43}, "q_QVrAZw": {"answer": 17}, "q_vpoC": {"answer": 1}, "q_q0T1j": {"answer": "f", "original_string": "of"}}}
