Question

Choose the correct set of articles from the given options in the following sentence against the blank space : 
"The teacher wrote _____ outline of a story on _____ blackboard."

Accepted Answer

Here's the explanation:

Option 2, "an, the," is the correct choice because:

*   **"an" before "outline":** The word "outline" begins with a vowel *sound* (even though the letter is 'o'). The article "an" is used before words that begin with a vowel sound to ensure smooth pronunciation. Therefore, "an outline" is grammatically correct.

*   **"the" before "blackboard":** "Blackboard" is being referred to as a specific, definite object in the classroom. The teacher wrote on *that particular* blackboard. The definite article "the" is used to refer to something specific or already known.

Now, let's examine why the other options are incorrect:

*   **Option 1: a, a:** "a outline" is incorrect because "outline" begins with a vowel sound, requiring "an" instead of "a." While "a blackboard" could be grammatically correct in a different context (e.g., "He bought a blackboard"), in this sentence, the blackboard is likely a specific one in the classroom, making "the blackboard" more appropriate.

*   **Option 3: the, a:** "The outline" would imply that a specific outline has already been mentioned or is otherwise known to the reader/listener. Without prior context, this is unlikely. "a blackboard" suffers from the same issue as in Option 1; "the blackboard" is more appropriate in this context.

*   **Option 4: a, the:** As explained above, "a outline" is incorrect because "outline" begins with a vowel sound, requiring "an" instead of "a." "the blackboard" is correct, but the first article makes the entire option incorrect.

Therefore, only Option 2, "an, the," correctly uses the articles based on the vowel sound of "outline" and the specific nature of the blackboard.
