From what I have learned about stingrays... They don't exactly "sleep" But they do go in a state of awareness when they "sleep" They sleep anytime they want (its not like they can tell time lol)
Mercantilism is a national economic policy that is designed to maximize the exports of a nation. Mercantilism was dominant in modernized parts of Europe from the 16th to the 18th centuries before falling into decline. So a mercantile country is strengthened by a strong economy and having a more exports than imports.
Hope this helps! :)
