Review the transcript of Detective Miller's interrogation. When asked, "How many of the stolen diamonds do you have hidden in your basement?", which of the suspect's replies are grammatically correct? Select ALL that apply.

The correct answers are: I have none! I don't have any! None of those diamonds are in my house!

None can stand entirely alone as a pronoun to mean "not any amount" (I have none).

Any is perfectly paired with the negative auxiliary verb "don't" (don't have any).

None of is correctly followed by a determiner and a noun (None of those diamonds).

"No of them" is incorrect because "no" cannot be followed by "of"; you must use "none of."

"Don't have none" is an incorrect double negative.

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.

Interrogative sentence or clause

✅ Are you ready? — yes/no question (inversion: auxiliary before subject)
✅ What do you want? — wh-question (do-support + wh-word)
✅ Does she know? — yes/no question (do-support)
❌ You are ready? — sounds like a surprised echo, not a standard question

An interrogative sentence asks a question using inversion (auxiliary before subject) or do-support. Two main types: yes/no questions (Are you…?) and wh-questions (What/Where/When/Why/How…?).

Rule: standard English questions REQUIRE inversion or do-support. Simply raising intonation (You like coffee?) is informal/echo only.

English Grammar Basics

She is a teacher. — verb be + noun complement
He runs every day. — present simple, third-person -s
They don't like coffee. — negation with do-support
I have two cats. — possession, countable noun, no article before plurals

These sentences demonstrate English Grammar Basics — the foundational patterns every other topic builds on: parts of speech, basic tenses, articles, and simple sentence structure.

If you can identify the verb, the subject, and count the noun correctly, you've nailed the basics that make everything else click.

B1 | Intermediate

✅ If I had more time, I would travel more. — second conditional
✅ The bridge was built in 1920. — passive voice
✅ She said she was tired. — reported speech with backshift
✅ Although it rained, we enjoyed the trip. — complex sentence with concession

These are B1 patterns — the CEFR intermediate level. At B1 you link ideas, use passive voice, handle reported speech, and manage second conditional — enough for travel, work basics, and everyday independence.

Marker: if you can explain why something happened and follow a news story, you're B1.

Medium

If I were you, I would apologise. — one rule (second conditional), but distractors like was tempt you
Answers require active thought, not instant pattern recognition
Vocabulary and context are realistic, not artificially simplified
Usually tests one rule, but the wrong answers are plausible

Medium marks middle-difficulty challenges: A2–B1, one rule tested, but with realistic distractors that require genuine understanding.

Use "Medium" when Easy feels too obvious but Hard feels overwhelming. This is where most productive learning happens — the sweet spot of difficulty.
