The correct answers are Every one of, Much of, and Few of.
Every one of: We cannot use every directly with a pronoun (e.g., "every them" is incorrect). We must use the structure every one of + pronoun.
Much of: Furniture is an uncountable noun. Because it is preceded by a specific determiner (the), we must use of after the quantifier (e.g., much of the, not much the).
Few of: Business partners is a plural countable noun preceded by the possessive determiner my. Therefore, we need of after the quantifier (e.g., few of my, not few my). We use few rather than a little because the noun is countable.
Determiner
- ✅ The cat sat on a mat. — articles as determiners
- ✅ My sister has three dogs. — possessive + numeral as determiners
- ❌ I went to the home. — wrong (idiomatic: I went home — no determiner)
- ❌ She is a good student. ✅ vs She is good student. ❌ — missing determiner
A determiner sits before a noun to specify which, how many, or whose. Types include articles, demonstratives, possessives, and quantifiers.
Rule: most singular countable nouns in English require a determiner — a cat, the cat, my cat, this cat. Dropping it (cat sat on mat) breaks the sentence.
Countable and uncountable
- ✅ some advice — ❌ an advice / advices (uncountable → no article, no plural)
- ✅ a piece of furniture — ❌ a furniture / furnitures
- ✅ How much water? — ❌ How many water? (uncountable → much)
- ✅ fewer people — ❌ less people (countable plural → fewer)
English nouns are either countable (take a/an, form plurals, use many/few) or uncountable (no plural, use much/little). The choice is partly arbitrary and must be memorised.
Test: can you put a number in front? Three chairs → countable. Three furnitures ❌ → uncountable. Use a unit phrase instead: three pieces of furniture.
Pronoun
- ✅ between you and me — ❌ between you and I (objective case after preposition)
- ✅ its colour — ❌ it's colour (it's = it is)
- ✅ She did it herself. — reflexive pronoun
- ✅ The person who called… — relative pronoun
Pronouns replace nouns: personal (I/me/my), demonstrative (this/that), relative (who/which/that), interrogative (who?/what?), reflexive (myself), indefinite (everyone/nobody). They carry case that nouns have lost.
Trap: pronouns are where English case still matters: I vs me, who vs whom, its vs it's. Get these wrong and it's instantly noticeable.
Possessive
- ✅ its tail — ❌ it's tail (it's = it is, not possessive)
- ✅ the students' essays — plural possessive (apostrophe after the s)
- ✅ Sarah's book — singular possessive ('s)
- ✅ a friend of mine — possessive pronoun (not my)
Possessives show ownership: nouns use 's (singular) or s' (plural ending in s). Pronouns have special forms: my/mine, your/yours, his, her/hers, its, our/ours, their/theirs.
Trap: its (possessive) vs it's (= it is). Possessive pronouns NEVER use apostrophes — that's the opposite of nouns.
C1 | Advanced
- ✅ Not only did she finish early, but she also helped others. — inversion for emphasis
- ✅ It is the process that matters, not the result. — cleft sentence
- ✅ I insist that he be present. — formal subjunctive
- ✅ Were I to disagree, I would say so. — inverted conditional
These are C1 structures — the CEFR advanced level. At C1 you control inversion, cleft sentences, subjunctive forms, and register-switching fluently across formal and informal contexts.
Marker: if you can restructure a sentence for rhetorical effect without hesitation, you're C1.
Hard
- Had she not intervened, the situation would have escalated. — inverted conditional
- All distractors are grammatically plausible in other contexts
- Multiple rules interact (e.g., tense + aspect + modality)
- Context determines the answer — no single "rule" is enough
Hard marks upper-intermediate to advanced challenges: B2+, interacting rules, edge cases, plausible distractors, and contexts where pattern-matching fails.
Use "Hard" when Easy/Medium feel trivial and you want to test whether you actually understand a rule versus just recognising surface patterns.
