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_FRG3EU):
How many times does the letter "a" appear in the text: "but can"? Respond with an integer.

Question 1 (Question id: q_zFixjthY):
How many times does the letter "f" appear in the text: "days following each"? Respond with an integer.

Question 2 (Question id: q_cLY4I7):
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: "have"



Output JSON where all question ids are keys, omitting q_cLY4I7.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

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_zFixjthY": {"answer": 1}, "q_FRG3EU": {"answer": 1}, "global_metadata": {"num_questions_asked": 3}}}
