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_tWyOCS8r):
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_IH9vIwd):
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: "in"

Question 2 (Question id: q_EJTS0):
Calculate ( ( 9 - -2 ) ).



Return a JSON with each question id as a key.

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 response to a question is a string, add a 'first_char' field containing its first character.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
• num_questions_answered – number you actually answered.
• questions_with_integer_answers: ids of questions with integer replies.

Now provide the result JSON using the described format.
