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_4cmS5D):
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_nJPhutlU):
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 1 praying mantis, 3 fireflys, 3 deers, 3 insects, 2 starfishs?
 Respond with an integer.



Output JSON where all question ids are keys, omitting q_4cmS5D.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.
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: how many questions were asked in total.

Now provide the result JSON using the described format.
