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_0WQiI):
How many times does the letter "o" appear in the text: "have answered Cooley"? Respond with an integer.

Question 1 (Question id: q_AN947qQ):
Find the value of o in the equation: 13*o + 24 = 141 Respond with an integer.

Question 2 (Question id: q_PnzmUtAm):
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: "why"



Output JSON where all question ids are keys, omitting q_0WQiI.

For every question id, supply an object whose 'answer' field stores the solution.
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 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:
'num_questions_asked' should equal the total questions that appeared.
'num_questions_answered' must hold the number of answered questions.

Now provide the result JSON using the described format.

{"ground_truth": {"q_PnzmUtAm": {"answer": "y", "original_string": "why"}, "q_AN947qQ": {"answer": 9}, "global_metadata": {"num_questions_asked": 3, "num_questions_answered": 2}}}
