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_smqKH):
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: "biology"

Question 1 (Question id: q_3Lj3y76):
Calculate 9 * 4 + -2.

Question 2 (Question id: q_qa1A):
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 shrimps, 3 cats, 2 lobsters, 4 butterflys?
 Respond with an integer.



Return a JSON with each question id (except for q_3Lj3y76) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Now provide the result JSON using the described format.
