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_lvDkiXJ):
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: "do"

Question 1 (Question id: q_waYr7):
Solve for y: 234*y - 15 = 687 Respond with an integer.



Return a JSON with each question id (except for q_waYr7) as a key.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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' should equal the total questions that appeared.

In addition, add 'combined_results' with:
  • integer_info: maps each id to its integer answer
  • sum_of_answers: the combined total

Now provide the result JSON using the described format.

{"ground_truth": {"q_lvDkiXJ": {"answer": "o", "answer_type": "string", "original_string": "do"}, "global_metadata": {"num_questions_asked": 2}, "combined_results": {"integer_info": {}, "sum_of_answers": 0}}}
