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_XBuogV):
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_LcEh6p):
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: "the"

Question 2 (Question id: q_rkpORnD):
Calculate ( ( -9 * -9 ) ).



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

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
• num_questions_answered: count of questions present in your JSON.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

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.
