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_pfZ9W2Z):
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_VMZFe6XF):
Calculate ( ( ( 2 / 2 + 7 ) ) ).



Output JSON where all question ids are keys, omitting q_pfZ9W2Z.

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, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
• num_questions_answered – number you actually answered.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Insert 'combined_results', which should hold:
  • integer_info: per-id integer answers
  • sum_of_answers: their total

Now provide the result JSON using the described format.

{"ground_truth": {"q_VMZFe6XF": {"answer": 8, "half_answer": 4}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 1, "questions_with_integer_answers": ["q_VMZFe6XF"]}, "combined_results": {"integer_info": {"q_VMZFe6XF": 8}, "sum_of_answers": 8}}}
