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_dSleP):
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: "like"

Question 1 (Question id: q_jffY0):
Calculate -4 - 7 * -5.



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'. 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.
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_dSleP": {"answer": "e"}, "q_jffY0": {"answer": 31}}}
