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_mi65PWoM):
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: "one"

Question 1 (Question id: q_1pYa9H):

Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
