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_wcbB9iZ):
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: "and"

Question 1 (Question id: q_zRIu):
Calculate 0 + 9 - 4.

Question 2 (Question id: q_rzQz):
Calculate 5 / 1.

Question 3 (Question id: q_aogS):
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 spider, 1 shrimp, 2 butterflys?
 Respond with an integer.

Question 4 (Question id: q_v3NJvvkg):

Question 5 (Question id: q_Ju6BYj8U):
Your task is to count how many legs there are in total when given a list of animals.

 Respond with an integer.

Question 6 (Question id: q_DH3HsGao):

Create a JSON object keyed by every question id except q_wcbB9iZ.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.

Now provide the result JSON using the described format.
