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_OeUrzj):
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: "tools"

Question 1 (Question id: q_a2atqfu):
How many times does the letter "r" appear in the text: "well know everything"? Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field. 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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

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.
