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_sj9x):
Solve for y: 234*y - 15 = 687 Respond with an integer.

Question 1 (Question id: q_rd6In8eZ):
Calculate 9 * 2.

Question 2 (Question id: q_0oj4m):
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"



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
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).
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.

Also include 'combined_results' consisting of:
  • integer_info: maps each id to its integer answer
  • sum_of_answers: the combined total

Now provide the result JSON using the described format.
