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_IlLXN):
Calculate 1 + -2 - -8.

Question 1 (Question id: q_Op7C5NB):
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 lions, 1 bee, 2 lobsters, 4 jellyfishs, 3 birds?
 Respond with an integer.

Question 2 (Question id: q_duHfn8Hr):
Solve for i: 18*i + 126 = 432 Respond with an integer.

Question 3 (Question id: q_Lknljda):
Calculate 8 - 0 - -4.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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.
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.
