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_uSmvzy6f):
Calculate 6 * 2.

Question 1 (Question id: q_xkjl1):
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: "like"



Return a JSON with each question id as a key.

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.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_uSmvzy6f": {"answer": 12, "half_answer": 6}, "q_xkjl1": {"answer": "e", "first_char": "e"}}}
