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_AOlviXJ):
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_GTdMh):
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: "but"

Question 2 (Question id: q_4LvuQhn):
Solve for u: 95*u = 285 Respond with an integer.

Question 3 (Question id: q_CE2oJchP):
How many times does the letter "s" appear in the text: "on this"? Respond with an integer.



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

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).
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.

Now provide the result JSON using the described format.

{"ground_truth": {"q_CE2oJchP": {"answer": 1}, "q_4LvuQhn": {"answer": 3}, "q_GTdMh": {"answer": "t", "first_char": "t", "original_string": "but"}, "global_metadata": {"num_questions_asked": 4}}}
