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_u6xg):
Calculate ( ( 4 * -6 ) ) * -7.

Question 1 (Question id: q_6AZbR1GL):
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: "support"



Output JSON where all question ids are keys, omitting q_6AZbR1GL.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_u6xg": {"answer": 168, "answer_type": "integer", "half_answer": 84}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_u6xg"]}}}
