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_Daii):
How many times does the letter "t" appear in the text: "And the Russian"? Respond with an integer.

Question 1 (Question id: q_xk3eR):
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: "water"



Return a JSON with each question id (except for q_Daii) as a key.

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).

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.
Record the answered-question count in the field 'num_questions_answered'.

Now provide the result JSON using the described format.

{"ground_truth": {"q_xk3eR": {"answer": "r"}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 1}}}
