Select the grammatically correct sentence.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. An intrepid explorer stumbled upon an uncharted cavern deep within the heart of the rainforest.
Error concept: Wrong use of articles
What is wrong: Options 1, 3, and 4 either use the or a incorrectly before explorer, cavern, or heart.
Grammatical concept: Articles (a, an, the) – “an” is used before vowel sounds, “the” is used for something specific, “a” for general.
Incorrectness of the concept in context: Since the explorer and cavern are being mentioned for the first time, an and an are correct. The heart of the rainforest is specific, so the is correct.
How to correct: Use an before intrepid explorer and an before uncharted cavern.
Correct phrase/ correction: An intrepid explorer stumbled upon an uncharted cavern deep within the heart of the rainforest.
Final sentence: An intrepid explorer stumbled upon an uncharted cavern deep within the heart of the rainforest.
Hence, the chosen option is correct.
