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_MGUxda):
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: "why"

Question 1 (Question id: q_6sZxxU):
Calculate ( 4 * 5 ) + -9.

Question 2 (Question id: q_6IG1w):
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 duck, 1 flatworm, 3 crabs, 2 cockroachs, 3 fireflys?
 Respond with an integer.

Question 3 (Question id: q_ZFm0ce):
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 chickens, 2 flatworms, 4 sea slugs, 2 dogs, 2 butterflys?
 Respond with an integer.



Return a JSON with each question id (except for q_ZFm0ce) 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.
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.
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.
