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_N5xs):
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_p351L3):
How many times does the letter "t" appear in the text: "want Besides"? Respond with an integer.

Question 2 (Question id: q_14cgo):
Calculate -1 + 6.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Now provide the result JSON using the described format.

{"ground_truth": {"q_N5xs": {"answer": "d", "answer_type": "string"}, "q_p351L3": {"answer": 1, "task_type": "letter_counting", "answer_type": "integer"}, "q_14cgo": {"answer": 5, "answer_type": "integer"}}}
