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_b9Qi):
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: "effects"

Question 1 (Question id: q_YdhyqMj):
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 deers, 4 fireflys, 2 scorpions?
 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.
When counting animal legs, include an 'animal_types' list of the distinct animal names (singular, sorted).

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.

Now provide the result JSON using the described format.
