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_50x6):
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 4 sea slugs, 2 birds, 1 praying mantis, 2 tigers, 2 fireflys?
 Respond with an integer.

Question 1 (Question id: q_h3wlY):
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 2 tigers, 2 crickets, 2 fireflys, 1 leech, 3 woodlouses?
 Respond with an integer.

Question 2 (Question id: q_tWRz8):
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: "also"



Output JSON where all question ids are keys, omitting q_50x6.

The value for each key should be an object that contains the answer in the field 'answer'. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.

Now provide the result JSON using the described format.

{"ground_truth": {"q_tWRz8": {"answer": "o", "original_string": "also"}, "q_h3wlY": {"answer": 74, "task_type": "leg_counting", "half_answer": 37}, "global_metadata": {"num_questions_asked": 3}}}
