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_4W6MHQyS):
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: "this"

Question 1 (Question id: q_3kn0X):
Calculate 1 - -9.

Question 2 (Question id: q_1USt7C):
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: "they"

Question 3 (Question id: q_0yYlb):
Calculate 7 * 6 - 3.

Question 4 (Question id: q_USE8IYtQ):
Calculate ( ( ( ( 0 * 8 ) ) ) / 9 ).



Produce a JSON object whose top-level keys are the question ids.

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.
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).
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.
