There are two types of articles, definite and indefinite.
Definite article, the, is used to describe a specific item: "I don't want just any chair, I want the chair!"
Indefinite articles, a and an, are used to describe any item of the same property: "Just find me a chair, I need to sit down and take a break."
"the" chair in the first example is referring to a specific chair that both the speaker and the listener are presumed to know.
"a" chair in the second example is simply referring to any chair.
I do recall seeing a fair number of these articles being the deciding factor in some tougher SC questions. I tried to search for them and didn't have any luck finding one.
I hope I was clear in the explanation. I am not as good at explaining SC as before.
Yep.
