The correct answer is "warm enough," which indicates that the water is sufficiently warm for swimming.
Adjective
- ✅ a tall building — ❌ a tally building
- ✅ The soup is hot — ❌ The soup is hotly
- ✅ a lovely small old table — ❌ a small lovely old table
- ✅ She seems tired — ❌ She seems tiredly
These bolded words are adjectives — words that describe nouns or pronouns. They sit before a noun (a tall building) or after a linking verb (The soup is hot).
Pattern: if a word can slot between a/the and a noun (a ___ thing) and can take -er/-est, it's almost certainly an adjective.
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.
