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_Z1gxvSEV):
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: "to"

Question 1 (Question id: q_ykmDi):
How many times does the letter "s" appear in the text: "easily all"? Respond with an integer.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_Z1gxvSEV": {"answer": "o", "answer_type": "string", "original_string": "to"}, "q_ykmDi": {"answer": 1, "answer_type": "integer"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_ykmDi"]}}}
