ANSWER KEY & EXPLANATIONS
1 (C) the
Why it is correct: “Most important” is a superlative adjective. Because a superlative represents the highest degree of something, it is unique (there is only one “most important” event). You must always use “the” before superlatives.
2 (C) the
Why it is correct: “First” is an ordinal number (số thứ tự). Ordinal numbers (first, second, third, etc.) indicate a specific, unique position in a sequence. Therefore, they strictly require “the”.
3 (D) no article
Why it is correct: “Teamwork” is an abstract, uncountable noun. When speaking generally about an abstract concept, we use no article (zero article).
4 (C) the
Why it is correct: “Best” is a superlative adjective. There can only be one “best” project, making it specific and unique. It must take “the”.
5 (A) a
Why it is correct: The CEO is introducing “short story” for the first time. The listeners don’t know which story it is yet, so we use the indefinite article “a”.
6 (A) a
Why it is correct: When stating a singular profession (“junior analyst”), you must use “a” or “an”. Because “junior” starts with a consonant sound, it takes “a”.
7 (D) no article
Why it is correct: “Dedication” is an abstract noun. Used in a general sense, it takes no article.
8 (C) the
Why it is correct: “Highest” is a superlative adjective. Superlatives always require the definite article “the”.

Why it is correct: “Second” is an ordinal number. It points to a specific, unchangeable rank in history. Ordinal numbers always take “the”.
11 (C) the
Why it is correct: A company or department only has one “Head” or “Director.” Because this job title is completely unique within the context, it takes “the” instead of “a/an”.
12 (B) an
Why it is correct: The campaign is being introduced for the first time. Because “incredibly” starts with a vowel sound, we use “an”.
13 (C) the
Why it is correct: This is the second mention of the campaign. Since the audience now knows exactly which campaign the CEO is talking about, it becomes specific and takes “the”.
14 (C) the
Why it is correct: “Hardest” is a superlative adjective. It represents the absolute extreme level of difficulty, meaning there is only one problem like it. It requires “the”.

GRAMMAR POINTS TO REMEMBER
1 The “Superlative” Rule:
- Whenever you use an adjective in its superlative form (best, worst, highest, lowest, most beautiful), you MUST put The in front of it.
- Why? Because if something is the “best” or the “tallest”, there is only one of it. It is entirely unique and specific.
- Example: “This is the best project.” / “She has the highest sales.”
2 The “Ordinal Number” Rule:
- Ordinal numbers (first, second, third, last) describe a precise, unique position in a sequence or timeline. You MUST use The.
- Example: “This is the first time we met.” / “He is the second person to win.”
3 The “Unique Title/Object” Rule:
- If a person or a thing is the only one in existence within that context, use The. This applies to words like only, right, wrong, main.
- Example: “He is the CEO.” (There is only one CEO).
- Example: “You are the only person I trust.”
