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_yeSB0):
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_DzDKQ9MD):
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 butterflys, 4 lobsters, 3 lions?
 Respond with an integer.

Question 2 (Question id: q_gE9acywf):
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 crabs, 3 beetles, 1 cricket, 4 starfishs?
 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. 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 integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.
