Complete the exhausted college student's complaint about her backpack weight.
"I don't know why the professor assigned _____ massive textbook," groaned Sarah, dropping the 10-pound book directly onto her desk with a loud thud.
The correct answer is this.
"This" is used for a singular object that is physically close to the speaker (like a book she was just holding and dropped on her own desk). "That" would be used if the book were far away.
Demonstrative
- ✅ This book is mine. — singular, near (determiner)
- ✅ Those are expensive. — plural, far (pronoun)
- ❌ These book is mine. — number mismatch (plural demonstrative + singular noun)
- ✅ I didn't expect that. — pronoun referring back to a previous idea
Demonstratives (this/that/these/those) point to which thing you mean. This/these = near (in space or time). That/those = far. They work as determiners before nouns or as standalone pronouns.
Rule: demonstrative must agree in number with the noun — this book (singular) / these books (plural). Getting this wrong is instantly noticeable.
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.
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.
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.
