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_6R6CLgyw):
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: "extinction"

Question 1 (Question id: q_uMswI):
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: "of"

Question 2 (Question id: q_sr8WpY):
Calculate 0 * 1.

Question 3 (Question id: q_jdoeW3v):
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, 2 ants, 4 starfishs, 1 grasshopper?
 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'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
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.
