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_eX6gMY):
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: "is"

Question 1 (Question id: q_GYJA):
Solve for n: 36 - 13*n = -120 Respond with an integer.

Question 2 (Question id: q_JHtKk):
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 crabs, 1 horse, 3 insects?
 Respond with an integer.

Question 3 (Question id: q_mh9d):
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 insects, 1 giraffe, 1 cricket, 3 fireflys, 1 beetle?
 Respond with an integer.



Return a JSON with each question id (except for q_mh9d) 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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.
