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_MvF34g):
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: "always"

Question 1 (Question id: q_cEHlYB):
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 beetles, 2 ants, 4 sheeps, 2 cockroachs?
 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 a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.
For animal-leg questions, add 'animal_types': an alphabetically-sorted list of unique animal names in singular form.

Now provide the result JSON using the described format.
