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_P5KfOs):
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 1 (Question id: q_2HM2dZC):
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: "just"



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer 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.
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_P5KfOs": {"answer": "d", "answer_type": "string", "first_char": "d"}, "q_2HM2dZC": {"answer": "t", "answer_type": "string", "first_char": "t"}}}
