Choose the most appropriate article for the given blank in a sentence.

In the good old days of the Daimios, there lived ______ old couple whose only pet was a little dog.

Correct option is D

Explanation:

The correct answer is an.

In this sentence, we use the indefinite article "an" because we are referring to a singular noun (an old couple), but the identity of the couple is not specified. The article "an" is used before words that start with a vowel sound. "Old" begins with a vowel sound (the "o" sound), so we use "an" before it.

Information Booster:

Indefinite Articles (a, an):

"An" is used when the noun it precedes starts with a vowel sound, and "a" is used for consonant sounds.

Examples:
"An old couple" (because "old" starts with a vowel sound, "o").
"A young man" (because "young" starts with a consonant sound, "y").

The noun "old couple" is indefinite (not referring to a specific couple), and it follows the word "an" because the adjective "old" starts with a vowel sound. This makes "an" the most appropriate choice.

Articles in English:

Definite Article ("the"): Used when referring to something specific or previously mentioned.

Indefinite Articles ("a" and "an"): Used when referring to something nonspecific or when the identity is unknown.

Additional Knowledge:

"The" is not correct here because "the" is used to refer to something specific, and the couple in this sentence is not identified as such.

"A" is incorrect because "old" starts with a vowel sound, and we need "an" before such sounds.
