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_Iq5SyjYp):
How many times does the letter "i" appear in the text: "USE THIS"? Respond with an integer.

Question 1 (Question id: q_UcQh1):
Determine the value of b that satisfies: 216*b = 2592 Respond with an integer.

Question 2 (Question id: q_v5vF3Fm):
Calculate ( 7 + 8 ).



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

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.
