✅ Answer: A. usually
Usually is a frequency adverb, so it tells us how often something happens. The other three describe place (upstairs), manner (urgently), or fairness (unfairly), so none of them fits the sentence naturally.

Common Mistakes When Using U-Adverbs
-
Using Normally Where It Contradicts the Sentence
✕Incorrect: I usually don’t eat spicy food, but today is normally different.
✓Correct: I don’t usually eat spicy food, but today is different.
Why? Normally means in most cases — so today is normally different says the exception is the rule, which cancels itself out. If a day is unlike the others, it’s simply different.
-
Using Upstairs with an Unnecessary Preposition
✕Incorrect: She went to upstairs after dinner.
✓Correct: She went upstairs after dinner.
Why? Upstairs already carries the direction, so it needs no to. The same is true of downstairs, outside, home, and abroad: we went home, not we went to home.
-
Using Unexpectedly for Something That Was Planned
✕Incorrect: The meeting unexpectedly started at 9:00 because that was the scheduled time.
✓Correct: The meeting started at 9:00 as scheduled.
✓Correct: The meeting unexpectedly started thirty minutes early.
Why? Unexpectedly means nobody saw it coming. An event that happened exactly as planned is the opposite of unexpected.
-
Using Urgently When There Is No Urgency
✕Incorrect: She urgently drank a glass of water after lunch.
✓Correct: She calmly drank a glass of water after lunch.
✓Correct: She urgently called the doctor after the accident.
Why? Urgently belongs to actions that can’t wait. Attached to something ordinary, it sounds either alarming or accidental.
-
Confusing Unfair with Unfairly
✕Incorrect: The player was unfairly during the match.
✓Correct: The player was unfair during the match.
✓Correct: The player behaved unfairly during the match.
Why? The two fixes work differently, and the verb decides which one you need.
After a linking verb like was, use the adjective — it describes the player. With an action verb like behaved, played, or treated, use the adverb — it describes what was done.
-
Using Utterly with the Wrong Kind of Adjective
✕Incorrect: She was utterly happy about the surprise.
✓Correct: She was extremely happy about the surprise.
✓Correct: She was utterly exhausted after the marathon.
Why? Utterly goes with absolute adjectives — ones that can’t be measured in degrees: exhausted, impossible, ridiculous, silent. Happy comes in degrees, so it takes very or extremely instead.
