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_dkWr2):
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 1 (Question id: q_dMWr1Zk):
Calculate ( 5 - 2 ) - -3.

Question 2 (Question id: q_ZZVeb6U):
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: "why"



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.
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_dkWr2": {"answer": "e", "first_char": "e", "original_string": "the"}, "q_dMWr1Zk": {"answer": 6, "half_answer": 3}, "q_ZZVeb6U": {"answer": "y", "first_char": "y", "original_string": "why"}}}
