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_fPGew):
Calculate 8 + 7 + -9.

Question 1 (Question id: q_4fDikk):
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: "others"

Question 2 (Question id: q_SaYOw):
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: "behavior"

Question 3 (Question id: q_WHJ73ear):
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 butterflys, 3 lobsters, 3 elephants, 4 sheeps, 2 insects?
 Respond with an integer.

Question 4 (Question id: q_th4kzh):
How many times does the letter "k" appear in the text: "Gutenberg works 1"? Respond with an integer.



Return a JSON with each question id (except for q_fPGew) as a key.

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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_th4kzh": {"answer": 1}, "q_WHJ73ear": {"answer": 94, "additional_answer_info": {"half_answer": 47, "double_answer": 188}}, "q_4fDikk": {"answer": "s", "first_char": "s", "original_string": "others"}, "q_SaYOw": {"answer": "r", "first_char": "r", "original_string": "behavior"}}}
