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_hzpePf7f):
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: "water"

Question 1 (Question id: q_1Xuk3MU):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 3 spiders, 4 ants, 1 beetle?
 Respond with an integer.



Return a JSON with each question id as a key.

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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

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

Now provide the result JSON using the described format.

{"ground_truth": {"q_hzpePf7f": {"answer": "r"}, "q_1Xuk3MU": {"answer": 54, "additional_answer_info": {"half_answer": 27, "double_answer": 108}}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_1Xuk3MU"]}}}
