Help the weary wizard complete his disastrous food review.

I have tasted thirty different enchanted cupcakes today, and to my absolute horror, ___ turned me into a different species of amphibian.

The correct answer is every one of them.

The quantifier "every" cannot be followed directly by "of". To use it with a pronoun like "them", you must add "one" to create the structure: every one of + pronoun.

"Each them" is missing the preposition "of", and "all of it" is incorrect because "cupcakes" is a plural countable noun.

To ChallengesPreviousNext

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.

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.

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.

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.
