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_tY37Nkd):
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: "humans"

Question 1 (Question id: q_lrANtk):
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 beetles, 1 sea slug, 4 praying mantiss?
 Respond with an integer.

Question 2 (Question id: q_RTgM2):

 Respond with an integer.

Question 3 (Question id: q_0M0J):
Calculate ( -6 + 8 ) / 1.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
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.

Now provide the result JSON using the described format.
