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_DeD1):
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: "countries"

Question 1 (Question id: q_Iji7):
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: "to"



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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.

{"ground_truth": {"q_DeD1": {"answer": "s", "answer_type": "string"}, "q_Iji7": {"answer": "o", "answer_type": "string"}}}
