Fill in the blanks with the suitable Adverb from the options given below:
The baby slept _____.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Soundly
An adverb is a word that tells how, when, where or how much something happens. It can also describe an adjective or another adverb, for example she sings sweetly, very hot.
Complete sentence: The baby slept soundly. The blank follows the verb "slept", so it needs an adverb.
| Option | What it tells | Example |
|---|---|---|
| (1) Sound | "Sound" is an adjective (a sound sleep). As an adverb it survives mainly in the fixed phrase "sound asleep". After "slept" the standard adverb is "soundly". | – |
| (2) Peace | "Peace" is a noun. The adverb is "peacefully". | – |
| (3) Cradle | A cradle is a baby's bed. A noun cannot follow "slept" without a preposition ("slept in the cradle"). | – |
| (4) Soundly (answer) | adverb of manner: it tells how an action is done and is usually formed by adding -ly to an adjective: sound → soundly. Soundly means deeply and peacefully. | After the long journey, the children slept soundly. |
Contrast: the adjective sound describes a noun (a sound sleep). The adverb soundly describes a verb (slept soundly).
