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_2uKK):
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: "is"

Question 1 (Question id: q_hmyXcvy):
How many times does the letter "y" appear in the text: "be clearly"? Respond with an integer.

Question 2 (Question id: q_VaSQE):
Determine the value of f that satisfies: 8 - 13*f = -174 Respond with an integer.

Question 3 (Question id: q_BR8l):
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: "professional"



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

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.

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: ids of questions with integer replies.

Attach a 'combined_results' object that contains:
  • integer_info: per-id integer answers
  • sum_of_answers: their total

Now provide the result JSON using the described format.
