Question

Fill in the blanks using appropriate articles:
 ______ moon goes round ______ earth every 27 days.
a. A; a
b. The; the
c. A; the
d. The; a

Answer 1

Hint: An article is a word used to modify a noun, which is a person, place, object, or idea.The definite article ‘the' is used before unique things, i.e., things that are particular or one of their kind.

Complete answer:
In this question, the moon and the earth are unique, i.e., there is only one of each. Therefore, we have to use the definite article before both of them.

Let us analyze the options given to us in this question:
Option (a.), 'a; a', uses two indefinite articles.
Therefore, option (a.) is incorrect as we have to use the definite article before both of them.

Option (b.), ‘the; the', uses two definite articles.
Therefore, option (b.) is correct.

Option (c.), ‘a; the', uses one indefinite and one definite article.
Therefore, option (c.) is incorrect as we have to use the definite article before both of them.

Option (d.), ‘the; a', uses one definite and one indefinite article.
Therefore, option (d.) is incorrect as we have to use the definite article before both of them.

Note: You should keep in mind that the definite article (the) is used before a noun to indicate to the reader that the identity of the noun is known. The indefinite article (a, an) is used before a noun when it is general or when its identity is not known. However, there are certain situations in which a noun takes no article.
