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_aLoF0eC):
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 1 (Question id: q_gmX1RaL):
Calculate ( 1 / 1 ).

Question 2 (Question id: q_Fk3jdz8M):
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"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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_aLoF0eC": {"answer": "d", "first_char": "d", "original_string": "and"}, "q_gmX1RaL": {"answer": 1}, "q_Fk3jdz8M": {"answer": "t", "first_char": "t", "original_string": "it"}}}
