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_bTirW5x):
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: "part"

Question 1 (Question id: q_MMWmxsl8):
Calculate 2 * 4.

Question 2 (Question id: q_3akOS):
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 3 (Question id: q_wSeHf):
Find the value of y in the equation: 21*y + 2 = 296 Respond with an integer.

Question 4 (Question id: q_ThpVGfnB):
Calculate -3 + 7.



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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Attach a 'combined_results' object that contains:
  • integer_info holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.
