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_3CwI):
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_EAN0):
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"



Create a JSON object keyed by every question id except q_3CwI.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
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).
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Insert 'combined_results', which should hold:
  • integer_info (id → integer answer)
  • sum_of_answers (sum of those integers)

Now provide the result JSON using the described format.

{"ground_truth": {"q_EAN0": {"answer": "d", "answer_type": "string", "first_char": "d", "original_string": "and"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": []}, "combined_results": {"integer_info": {}, "sum_of_answers": 0}}}
