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_wJa5JLX):
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 praying mantiss, 4 cats, 3 beetles, 3 spiders, 3 crabs?
 Respond with an integer.

Question 1 (Question id: q_4pxwqxLt):
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: "careers"



Produce a JSON object whose top-level keys are the question ids.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.
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.
• num_questions_answered: count of questions present in your JSON.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Now provide the result JSON using the described format.
