Here are three instances regarding the usage of articles:
From a poll on the Internet: "Should the owner of a shop be able to buy from or sell to their shop?"
From Wikipedia: "Birds of prey, also known as raptors, hunt and feed on other animals."
"Waves of radiation are called sine waves."
In 1, can the phrase "the owner of a shop" have the same reference as that of "owners of a shop"?
In 2, can the phrase "birds of prey" have the same reference as that of "the birds of prey"?
In 3, does the phrase "waves of radiation" have the same reference as that of "the waves of radiation"?
My answers are yes, no, yes. Am I right?
