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_G0xMojU):
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: "affect"

Question 1 (Question id: q_YQkr):
Find the value of b in the equation: 256*b + 144 = 1680 Respond with an integer.

Question 2 (Question id: q_eDGPY):
Calculate ( 1 + 0 ) / 1.

Question 3 (Question id: q_BqZ8wyR):
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 lion, 1 cow, 1 horse?
 Respond with an integer.



Return a JSON with each question id as a key.

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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.
