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_7kuq):
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_oPWU):
Calculate ( 6 - 7 ) - -3.



Create a JSON object keyed by every question id except q_7kuq.

The value for each key should be an object that contains the answer in the field 'answer'.
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.
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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.

Attach a 'combined_results' object that contains:
  • integer_info – object mapping ids to their integer answers
  • sum_of_answers – sum of those integers

Now provide the result JSON using the described format.

{"ground_truth": {"q_oPWU": {"answer": 2, "answer_type": "integer", "half_answer": 1}, "global_metadata": {"num_questions_asked": 2}, "combined_results": {"integer_info": {"q_oPWU": 2}, "sum_of_answers": 2}}}
