• Analysis of incorrect options: (A) “well” is an adverb and cannot modify a noun in this context. (B) “best” is superlative and needs “the”. (D) “greatly” is a structural error as it is an adverb.

• Analysis of incorrect options: (A) “careful” is an adjective. (B) “safely” is a strong distractor; grammatically it works, but contextually, a coach watches “carefully” (with attention), not “safely”. (D) “care” is a noun/verb.

10  (D) tired

• Why it’s correct: “Felt” (from feel) is a linking verb. It must be followed by an adjective describing the team.

14  (A) incredibly

• Why it’s correct: We need an adverb to modify the adjective “strong”. Adverbs can modify adjectives to show degree.

(C) “heavily” is an adverb but doesn’t collocate well with “run” in this exact structure. (D) “hardness” is a noun.

16  (A) well

• Why it’s correct: When referring to health, “well” is used as an adjective. “Feeling well” means feeling healthy.

• Analysis of incorrect options: (A) “bad” is a common mistake (using an adjective to modify another adjective). (C) “worse” is a comparative adjective/adverb, but requires a comparison context. (D) “badness” is a noun.

20  (C) early

• Why it’s correct: “Early” is an irregular word that is both an adjective and an adverb. Here, it acts as an adverb modifying “arrived”.
• Analysis of incorrect options: (A) “earlily” is a structural error (this word does not exist). (C) “earliness” is a noun. (B) “soonest” is superlative and does not fit the context without “the”.

• Adjectives vs. Adverbs: Adjectives describe nouns (people, places, things). Adverbs describe verbs (actions), adjectives, or other adverbs.
• Example: He is a quick runner (Adj). He runs quickly (Adv).
• The “Good / Well” Rule: “Good” is an adjective. “Well” is the adverb form of good.
• Example: She is a good player. She plays well.
• Exception: “Well” is also used as an adjective when talking about health (e.g., I don’t feel well today).
• Linking Verbs (Verbs of Senses): Verbs like look, feel, sound, taste, smell, seem, and be are followed by Adjectives, not adverbs!
• Example: You look happy! (NOT happily). The food tastes delicious! (NOT deliciously).
• Irregular Adverbs: Some words don’t change form. They are the same as adjectives and adverbs.
• Fast -> Fast (NOT fastly)
• Hard -> Hard (Note: “Hardly” exists, but it means “almost zero/almost not”, e.g., I hardly slept = I slept almost zero hours).
• Early -> Early
• Late -> Late (Note: “Lately” exists, but it means “recently”).
