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_OY1nC):
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 crabs, 3 cockroachs, 4 chickens, 3 cats?
 Respond with an integer.

Question 1 (Question id: q_Cdb7LB9):
How many times does the letter "k" appear in the text: "work required"? Respond with an integer.

Question 2 (Question id: q_7Uro0f2):
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"



Return a JSON with each question id as a key.

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

Now provide the result JSON using the described format.

{"ground_truth": {"q_OY1nC": {"answer": 68, "half_answer": 34}, "q_Cdb7LB9": {"answer": 1}, "q_7Uro0f2": {"answer": "d", "original_string": "and"}}}
