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_u5WB1s):
Determine the value of d that satisfies: 12*d + 15 = 111 Respond with an integer.

Question 1 (Question id: q_1Fyw3):
Solve for t: 18*t + 28 = 226 Respond with an integer.

Question 2 (Question id: q_d1DfeNM):
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: "play"



Return a JSON with each question id (except for q_d1DfeNM) as a key.

Each key’s value must be an object holding an 'answer' field.
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.
For last-character tasks, provide 'original_string' alongside the answer.

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' must hold the number of answered questions.

Also include 'combined_results' consisting of:
  • integer_info: per-id integer answers
  • sum_of_answers: their total

Now provide the result JSON using the described format.
