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_1sDK):
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: "economy"

Question 1 (Question id: q_qqNTW9Nt):
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: "we"

Question 2 (Question id: q_UeMB3rW):
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: "in"

Question 3 (Question id: q_sZfO):
Calculate ( -5 * -8 ).



Create a JSON object keyed by every question id except q_1sDK.

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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_sZfO": {"answer": 40, "half_answer": 20}, "q_UeMB3rW": {"answer": "n"}, "q_qqNTW9Nt": {"answer": "e"}, "global_metadata": {"num_questions_asked": 4, "questions_with_integer_answers": ["q_sZfO"]}}}
