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_MFj166l1):
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: "it"

Question 1 (Question id: q_KWC5VXs):
Calculate ( -2 * 7 ) * -5.

Question 2 (Question id: q_sdtxE):
Calculate ( -3 * 2 + 7 ).



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.
Record the answered-question count in the field 'num_questions_answered'.
• questions_with_integer_answers: ids of questions with integer replies.

Now provide the result JSON using the described format.
