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_1WDnipW):
Calculate ( ( -3 + 5 ) ).

Question 1 (Question id: q_lvUUCshv):
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: "how"



Produce a JSON object whose top-level keys are the question ids.

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.
For string answers, include 'first_char' with the answer’s initial letter.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

In addition, add 'combined_results' with:
  • 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.
