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_whzr):
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: "things"

Question 1 (Question id: q_i5a66V):
Solve for k: 27*k - 10 = 314 Respond with an integer.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
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).
For string answers, include 'first_char' with the answer’s initial letter.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
• num_questions_answered: count of questions present in your JSON.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

In addition, add 'combined_results' with:
  • integer_info holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.
