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_TfRzY9hv):
How many times does the letter "s" appear in the text: "As for"? Respond with an integer.

Question 1 (Question id: q_hFpWm):
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: "a"



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
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.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.

Now provide the result JSON using the described format.

{"ground_truth": {"q_TfRzY9hv": {"answer": 1}, "q_hFpWm": {"answer": "a", "first_char": "a", "original_string": "a"}, "global_metadata": {"num_questions_asked": 2}}}
