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_qW377):
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: "how"

Question 1 (Question id: q_po1ar):
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"



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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.

{"ground_truth": {"q_qW377": {"answer": "w"}, "q_po1ar": {"answer": "d"}}}
