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_zROEi):
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: "all"

Question 1 (Question id: q_dDaDdP):
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: "is"



Return a JSON with each question id (except for q_zROEi) 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.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_dDaDdP": {"answer": "s", "answer_type": "string", "original_string": "is"}}}
