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_ENRWR):
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: "world"

Question 1 (Question id: q_nWErU):
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 lobster, 1 chicken, 1 insect?
 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
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.

{"ground_truth": {"q_ENRWR": {"answer": "d", "first_char": "d"}, "q_nWErU": {"answer": 18, "half_answer": 9}}}
