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_pQaX9K):
How many times does the letter "f" appear in the text: "a library of"? Respond with an integer.

Question 1 (Question id: q_aXwI):
How many times does the letter "d" appear in the text: "a day"? Respond with an integer.



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

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.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.

Now provide the result JSON using the described format.

{"ground_truth": {"q_pQaX9K": {"answer": 1}, "global_metadata": {"num_questions_asked": 2}}}
