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_PGbQs):
How many times does the letter "8" appear in the text: "the year 2889"? Respond with an integer.

Question 1 (Question id: q_lEcL4):
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: "of"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_PGbQs": {"answer": 2, "answer_type": "integer", "half_answer": 1}, "q_lEcL4": {"answer": "f", "answer_type": "string"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_PGbQs"]}}}
