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_udttS):
How many times does the letter "n" appear in the text: "Do not"? Respond with an integer.

Question 1 (Question id: q_fiDeiv):
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: "it"

Question 2 (Question id: q_VjbJDIn):
Calculate ( ( ( -7 / 7 ) ) ) - -8.

Question 3 (Question id: q_W2sb):
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 fireflys, 1 horse, 2 spiders, 1 giraffe, 4 leechs?
 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

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 string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_udttS": {"answer": 1}, "q_fiDeiv": {"answer": "t", "first_char": "t", "original_string": "it"}, "q_VjbJDIn": {"answer": 7}, "q_W2sb": {"answer": 42, "half_answer": 21}}}
