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_6oTV0):
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: "and"

Question 1 (Question id: q_ke0K4hO0):
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: "or"

Question 2 (Question id: q_4gLJrT):
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 4 lions, 3 praying mantiss, 1 giraffe, 2 horses, 2 elephants?
 Respond with an integer.

Question 3 (Question id: q_uhSTc):
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 grasshopper, 3 bees, 2 ducks, 1 scorpion?
 Respond with an integer.



Output JSON where all question ids are keys, omitting q_ke0K4hO0.

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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_4gLJrT": {"answer": 54, "half_answer": 27}, "q_uhSTc": {"answer": 36, "half_answer": 18}, "q_6oTV0": {"answer": "d", "original_string": "and"}}}
