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_oy9j8qiV):
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: "functioning"

Question 1 (Question id: q_pbYwJUUR):
How many times does the letter "r" appear in the text: "name Fritz"? Respond with an integer.



Create a JSON object keyed by every question id except q_oy9j8qiV.

For every question id, supply an object whose 'answer' field stores the solution.
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).
If the response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.
• num_questions_answered – number you actually answered.

Now provide the result JSON using the described format.

{"ground_truth": {"q_pbYwJUUR": {"answer": 1}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 1}}}
