To justify the answer, I make a quotation from the bank of the republic of Colombia web page that provided the definition of GDP  "The GDP is the total of goods and services produced in a country during a given period of time. it includes the production generated by nationals resident in the country and by foreigners resident in the country, and excludes the production of nationals resident abroad" the previous definition is exactly how GDP works.

due to this result, wilhelm wundt also able to make psychology to be acknowledged as a separate scientific field from biology.

well, there are a lot of places we get information about earth from. like science classes, websites, books, newspapers, etc.
