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_Nyb8):
Calculate -8 - -9 - -2.

Question 1 (Question id: q_wuXOL1N):
How many times does the letter "a" appear in the text: "000 are"? Respond with an integer.

Question 2 (Question id: q_Hz2VfLL4):
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: "the"

Question 3 (Question id: q_psX4C6Cc):
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 birds, 3 sea slugs, 2 giraffes, 4 ants?
 Respond with an integer.



Output JSON where all question ids are keys, omitting q_wuXOL1N.

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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_psX4C6Cc": {"answer": 36, "half_answer": 18}, "q_Nyb8": {"answer": 3}, "q_Hz2VfLL4": {"answer": "e", "first_char": "e"}}}
