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_QdKG4Zm):
Calculate ( -4 - -4 ).

Question 1 (Question id: q_gFZNC):
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 2 (Question id: q_O1CCtK):
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 cockroach, 2 deers, 4 fireflys, 4 starfishs, 4 woodlouses?
 Respond with an integer.

Question 3 (Question id: q_V1365):
Determine the value of g that satisfies: -195*g = -3510 Respond with an integer.



Return a JSON with each question id as a key.

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.
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.

{"ground_truth": {"q_QdKG4Zm": {"answer": 0, "half_answer": 0}, "q_gFZNC": {"answer": "d", "first_char": "d", "original_string": "and"}, "q_O1CCtK": {"answer": 114, "half_answer": 57}, "q_V1365": {"answer": 18, "half_answer": 9}}}
