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_skuSR2lj):
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: "again"

Question 1 (Question id: q_UGND):
Determine the value of q that satisfies: 2*q + 8 = 22 Respond with an integer.

Question 2 (Question id: q_bzWq0YP):
Calculate 5 + 8.



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

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
Set 'num_questions_asked' to the count of questions originally displayed.
• num_questions_answered – number you actually answered.

Create a 'combined_results' section featuring:
  • integer_info: maps each id to its integer answer
  • sum_of_answers: the combined total

Now provide the result JSON using the described format.

{"ground_truth": {"q_bzWq0YP": {"answer": 13}, "q_skuSR2lj": {"answer": "n", "first_char": "n", "original_string": "again"}, "global_metadata": {"num_questions_asked": 3, "num_questions_answered": 2}, "combined_results": {"integer_info": {"q_bzWq0YP": 13}, "sum_of_answers": 13}}}
