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_mBNz):
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: "others"

Question 1 (Question id: q_VcCEj3OQ):
How many times does the letter "o" appear in the text: "Faithburn out"? Respond with an integer.

Question 2 (Question id: q_7Jm8UXB):
Calculate -1 + 8.



Output JSON where all question ids are keys, omitting q_mBNz.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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' should equal the total questions that appeared.
• num_questions_answered: count of questions present in your JSON.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Also include 'combined_results' consisting of:
  • integer_info holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.
