ANSWER KEY & EXPLANATIONS
1 (A) quietly
- Why it’s correct: We need an adverb to describe how the action (turned) was performed.

2 (B) dark
- Why it’s correct: “Was” is a linking verb (verb “to be”). It is followed by an adjective to describe the state of the living room.
- Analysis of incorrect options: (A) “darkly” is a Common Mistake (putting an adverb after a linking verb). (C) “darkness” is a Structural Error here. (D) “bright” is a Meaning Trap (if the lights are off, it cannot be bright).

8 (D) nervous

- Analysis of incorrect options: (B) “terribly” is a Common Mistake (adverb). (D) “terror” is a Structural Error (noun). (C) “wonderful” is a Meaning Trap (a loud noise giving you away isn’t wonderful).

- Why it’s correct: We need an adjective to describe the noun “sleeper”.
- Analysis of incorrect options: (B) “lightly” is a Common Mistake (adverb). (C) “lightness” is a Structural Error (noun). (A) “heavy” is a Strong Distractor/Meaning Trap (“heavy sleeper” means they don’t wake up easily, which contradicts “smallest sound can wake him up”).
14 (A) amazing
- Why it’s correct: “Smelled” is a linking verb of senses here. It must be followed by an adjective describing the subject (the cookies).
- Analysis of incorrect options: (D) “amazingly” is a Common Mistake (adverb after a linking verb). (C) “amaze” is a Structural Error (verb). (B) “awfully” is a Meaning Trap (cookies usually don’t smell awful).
15 (D) fast
- Why it’s correct: “Fast” is an irregular word that acts as both an adjective and an adverb. Here it is an adverb modifying “beating”.
- Analysis of incorrect options: (A) “fastly” is a very Common Mistake (this word does not exist in standard English). (B) “fasten” is a Structural Error (verb meaning to tie or close). (C) “hardly” is a Meaning Trap (“hardly beating” means almost stopping, which is the opposite of a racing heart).
16 (A) hard
- Why it’s correct: “Hard” is an irregular adverb modifying “breathing”. It means “with a lot of effort”.
- Analysis of incorrect options: (B) “hardly” is a Strong Distractor/Meaning Trap. It is an adverb, but it means “almost not at all” (e.g., I hardly slept), not “heavily”. (C) “hardness” is a Structural Error (noun). (D) “difficult” is a Common Mistake (adjective).
17 (C) late
- Why it’s correct: “Late” is an irregular adverb modifying “got home”. It means “after the expected time”.
- Analysis of incorrect options: (A) “lately” is a Strong Distractor/Meaning Trap. “Lately” is a real adverb, but it means “recently”, not “at a late hour”. (D) “lateness” is a Structural Error (noun). (B) “early” is a Meaning Trap (contradicts the context).
18 (D) sleepily
- Why it’s correct: Here, “looked AT” is an action verb (directing the eyes), not a linking verb. Therefore, we must use an adverb to describe how he looked.
- Analysis of incorrect options: (B) “sleepy” is a Common Mistake/Strong Distractor. Students often memorize “look + adjective” (linking verb rule), but here “look at” is an action. (A) “sleepiness” is a Structural Error (noun). (C) “completely” is a Meaning Trap (doesn’t make contextual sense here).
19 (C) silent
- Why it’s correct: “Stay” can act as a linking verb meaning “remain in a state”. It is followed by an adjective.
- Analysis of incorrect options: (A) “silently” is a Common Mistake (using an adverb after the linking verb ‘stay’). (B) “silence” is a Structural Error (noun). (D) “softly” is a Meaning Trap (wrong word choice for “zero noise state”).
20 (C) well
- Why it’s correct: We need an adverb to modify the action verb “slept”. The adverb form of good is “well”.
- Analysis of incorrect options: (A) “good” is a Common Mistake (adjective). (D) “best” is a Structural Error (superlative). (B) “badly” is a Meaning Trap (you want to pretend you slept normally, not badly, to avoid suspicion).
GRAMMAR POINTS TO REMEMBER
- Adjectives vs. Adverbs: Use Adjectives to describe nouns (things, people, places). Use Adverbs to describe verbs (actions), or how something is done.
- Example: A careful step (Adjective). I stepped carefully (Adverb).
- Linking Verbs (Verbs of Senses): Verbs like be, feel, look, smell, taste, seem, stay act as bridges. They are followed by Adjectives, NOT adverbs!
- Example: I feel nervous (NOT nervously). The house was dark (NOT darkly).
- Watch out: If “look” is an action (e.g., look at something), use an adverb! (He looked at me sleepily).
- The “Good / Well” Rule: “Good” is an adjective. “Well” is the adverb form.
- Example: A good plan. I planned it well.
- Irregular Adverbs (The Traps): Some words don’t change form by adding “-ly”.
- Fast ➔ Adverb is fast (Never “fastly”).
- Hard ➔ Adverb is hard. (“Hardly” means “almost zero/barely”, completely changing the meaning).
- Late ➔ Adverb is late. (“Lately” means “recently”).
