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_jhwOQfL1):
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: "part"

Question 1 (Question id: q_Lm1ejG):
Calculate ( 2 * 7 ).



Output JSON where all question ids are keys, omitting q_jhwOQfL1.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer 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:
Set 'num_questions_asked' to the count of questions originally displayed.
Add 'num_questions_answered' showing how many questions you answered.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Also include 'combined_results' consisting of:
  • integer_info – object mapping ids to their integer answers
  • sum_of_answers – sum of those integers

Now provide the result JSON using the described format.
