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_vUw2Z):
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: "that"

Question 1 (Question id: q_ohPZW3Q):
How many times does the letter "n" appear in the text: "anywhere in the"? Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

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.
• num_questions_answered – number you actually answered.

Now provide the result JSON using the described format.

{"ground_truth": {"q_vUw2Z": {"answer": "t"}, "q_ohPZW3Q": {"answer": 2, "half_answer": 1}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2}}}
