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_AYNL):
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: "of"

Question 1 (Question id: q_cJAzIF98):
Calculate ( 7 / 1 + 1 ).

Question 2 (Question id: q_4Ffm):
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 3 (Question id: q_zPN3):
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: "cycle"



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, 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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_AYNL": {"answer": "f", "first_char": "f"}, "q_cJAzIF98": {"answer": 8, "additional_answer_info": {"half_answer": 4, "double_answer": 16}}, "q_4Ffm": {"answer": "d", "first_char": "d"}, "q_zPN3": {"answer": "e", "first_char": "e"}}}
