Correct answer: D
Explanation
Correct Answer
Quietly
Explanation
The question asks to choose the grammatically correct word to replace the error in the sentence: "The baby slept quiet through the night."
The word needing replacement modifies the verb "slept". In English grammar, words that modify or describe actions (verbs) are called adverbs, and they typically end in "-ly". The word "quiet" is an adjective, which is used to describe nouns (e.g., "a quiet baby"). To describe how the baby slept, we must change the adjective into the adverb "quietly". Therefore, Option 4 is the correct choice.
The other options are incorrect because they are all adjectives, which cannot properly modify the verb "slept":
Calm is an adjective (e.g., "The water is calm"). The adverb form would be "calmly".
Soft is an adjective (e.g., "A soft pillow"). The adverb form would be "softly".
Peaceful is an adjective (e.g., "A peaceful sleep"). The adverb form would be "peacefully".
Key Points
A common trap in competitive exams is confusing adjectives with adverbs. Always ask yourself what the word is describing. If it describes a person, place, or thing (noun), use an adjective. If it describes an action (verb), look for the adverb form, which usually carries the "-ly" suffix.
