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_rLRz):
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 1 (Question id: q_s5i1):
Calculate ( 8 - -4 * 2 ).

Question 2 (Question id: q_sUGy):
Calculate ( 8 * 1 ) - 8.

Question 3 (Question id: q_y46p):
Calculate ( ( 4 / 2 ) - -4 ).



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.
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).

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

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.
