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_TU1c5s):
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: "and"

Question 1 (Question id: q_OXOs):
Determine the value of x that satisfies: 20 - 6*x = 2 Respond with an integer.



Return a JSON with each question id (except for q_TU1c5s) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
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.

Create a 'combined_results' section featuring:
  • integer_info holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.

{"ground_truth": {"q_OXOs": {"answer": 3}, "global_metadata": {"num_questions_asked": 2}, "combined_results": {"integer_info": {"q_OXOs": 3}, "sum_of_answers": 3}}}
