Choose the appropriate example of the Adverb of Reason:

The correct answer is Option (4) → "He was ill and hence missed the match."

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.

Adverb of reason:

• Some adverbs give the reason for an action. They tell why it happens. These are adverbs of reason (hence, therefore).
• In this sentence, hence means for this reason. He missed the match because he was ill.

Why the Other Options are Incorrect?

Option 1: "She always cooks dinner early." — Incorrect. "Always" tells how often (frequency) and "early" tells when (time). Neither word gives a reason.

Option 2: "He quickly finished his homework." — Incorrect. The adverb "quickly" tells how he finished his homework. It is an adverb of manner.

Option 3: "She unfortunately lost her wallet." — Incorrect. "Unfortunately" shows how the speaker feels about the event. It does not tell why she lost the wallet.
