Select the correct sentence.
Answers:
The correct sentence is "It's ten kilometers from here to the city center" because "it" is used to refer to distance.
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.
Grammatical number
- ✅ The data show… — ❌ The data shows… (traditionally plural)
- ✅ Each student has a book. — ❌ Each student have a book. (each = singular)
- ✅ The team is ready. (BrE: are also fine) — collective noun
- ✅ children, mice, teeth — irregular plurals (no -s)
Grammatical number = singular vs plural on nouns, pronouns, and verbs. Nouns usually add -(e)s; verbs must agree with their subject's number.
Trap: collective nouns (team, staff, data), quantifiers (each, every = singular; both, several = plural), and irregular plurals (children, criteria, phenomena) all cause agreement errors.
A1 | Elementary | Beginners
- ✅ My name is Anna. — present simple of be
- ✅ Where is the station? — basic *wh-*question
- ✅ I have two brothers. — possession with have
- ✅ She likes coffee. — third-person -s
These are A1 sentences — the starting level of the CEFR framework. At A1 you can introduce yourself, ask and answer simple personal questions, and handle basic everyday transactions using present tense, be/have/do, and core vocabulary.
If you can say these but freeze at normal speaking speed, you're solidly A1 — and that's exactly where to start.
Easy
- She is a teacher. — one verb form, one rule
- I have two cats. — basic possession, short sentence
- He doesn't like coffee. — simple negation with do-support
- Only one answer is clearly correct; distractors are obviously wrong.
Easy marks beginner-level challenges: A1–early A2, one rule at a time, everyday vocabulary, no trick questions.
Use "Easy" when you want to build confidence on a specific rule without interference from other grammar or tricky contexts.
