Articles MCQ (A / An / The) – Daily Practice Set with Answers

Explanation

• Correct option: C → a
• Reason: In “In the morning I go for a walk,” we use the indefinite article a before a singular countable noun that starts with a consonant sound (walk).
• Grammar rule: Use a before a/an + singular noun with a consonant sound; an before a vowel sound; the for a specific thing; zero article for plural/non-count nouns or generic statements.
• Why others are wrong: The would make it specific; An is before vowel sound; No article is incorrect for a singular countable noun here.

Question: He died without ________ heir.

• Correct answer: an

Explanation: Use a/an for a non-specific, single noun. "Heir" starts with a vowel sound, so we use an (not a). The indefinite article matches a singular countable noun introduced for the first time. Grammar rule: - a + consonant sound - an + vowel sound - the = definite article (specific) - zero article = no article (general plural or uncountable nouns) Why others are wrong: A. the → not specific here. C. a → incorrect before vowel sound. D. no article → needs an article before a singular countable noun.

Correct answer: the

• Rule: Use the for a specific person already known or mentioned.
• Why this fits: It refers to a particular, identifiable doctor.
• Why others are wrong:
  • A. the is correct;
  • B. an / C. a would make the doctor non-specific;
  • D. no article would generalize, not a specific doctor.

Answer: It was a unit of measurement.

• Rule: Use a before a singular count noun beginning with a consonant sound to mean “one,” non-specific (indefinite article).
• Why “a” is correct: “unit” starts with a consonant sound /juː/ (yoo-nit), so we use a.

Correct option: B - an

• Rule: Use a before a consonant sound and an before a vowel sound. Here unjust starts with a vowel sound /ʌ/, so we use an.
• Why others are wrong:
  • the unjust charge = refers to a specific charge; not indicated.
  • a unjust charge = incorrect because a before a vowel sound.
  • no article = ungrammatical with a countable noun like charge.

Explanation

• The correct answer is an because we use an before a word that begins with a vowel sound. hour starts with a silent h, so it sounds like "our" — a vowel sound.
• A would be wrong since hour does not start with a consonant sound.
• The is incorrect because the hour is not a specific known hour in this sentence.
• No article is incorrect for a singular countable noun here.

Grammar rule: Use a before consonant sounds, an before vowel sounds, the for specific items, and zero article for plural/uncountable in general.

Explanation in simple English

• Correct answer: D — no article.
• “Man” here means humankind in general, not one specific man. We use zero article for general statements about a class: “Man is mortal.”
• Rules:
  • a/an: used for any one member of a class (indefinite, specific noun with count).
  • the: used for a specific person/item or a unique thing.
  • zero article: used for general statements or plural/general nouns.
• Why others are wrong: A would mean a specific man; B is incorrect form; C is possible but changes meaning to “a man” not a general statement.

Explain the answer

• Correct option: C — a.
• Reason: Before a singular, countable noun, use the indefinite article a or an; here noise starts with a consonant sound, so we use a noise.
• Rule: a/an = indefinite article for one item; the = definite article for a specific item; zero article = used with plural/uncountable nouns in general;
• Why others wrong: A) the makes it specific; B) an would be before a vowel sound; D) no article is wrong for a singular countable noun here.

Explanation (≤120 words)

• Correct answer: a — Use a before a singular, countable noun that begins with a consonant sound. union begins with a consonant sound (/juː/). So we say a union.
• A and the are not needed here: “a union” is non-specific; “the union” would refer to a known, particular union.
• An is incorrect because union starts with a consonant sound, not a vowel sound.
• No article is incorrect for a singular, countable noun requiring a determiner in this context.
