Jawaban:

Use "a" or "an" with a singular count noun when you mean "one of many," "any," "in general."

(a/an digunakan untuk benda satu yang bisa dihitung)

example:

Bob is a student (one of many students).

I like a good movie (one of many movies).

Use "the" with any noun when the meaning is specific;

for example, when the noun names the only one (or one) of a kind.

(the digunakan untuk macam benda yang mana dia bermakna spesifik)

example:

Adam was the first man (the only 'first man').

New York is the largest city in the United States (only one city can be 'the largest').

We live on the earth (the only Earth we know).

Have you heard the news (specific news)?

Penjelasan:

Don't Use "a," "an," or "the" with a non-count noun when you mean "any," "in general."

(jangan gunakan a/an/the pada benda yang tidak dapat dihitung)

ex:

We believe in love (in general).

He gave me information (not specific).
