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_vmyk4v):
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: "a"

Question 1 (Question id: q_2D8FWjj):
Calculate 5 + 5.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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).
If the response to a question is a string, add a 'first_char' field containing its first character.
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.

Insert 'combined_results', which should hold:
  • 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.
