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_zvuXL61):
Calculate ( 2 - 2 ).

Question 1 (Question id: q_0DGhV9z0):
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 2 (Question id: q_exsgrTzg):
How many times does the letter "t" appear in the text: "the United States"? Respond with an integer.



Create a JSON object keyed by every question id except q_zvuXL61.

Each key’s value must be an object holding an 'answer' field.
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.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_0DGhV9z0": {"answer": "d"}, "q_exsgrTzg": {"answer": 4, "half_answer": 2}, "global_metadata": {"num_questions_asked": 3, "questions_with_integer_answers": ["q_exsgrTzg"]}}}
