The correct answers are Agent 007 sneaks around more quietly than Agent 008. and Out of everyone in the agency, Agent 009 types passwords the most carefully.
Adverbs ending in "-ly" (like quietly and carefully) form their comparatives with "more" and their superlatives with "most".
"Fast" does not take an "-ly" ending; it remains "faster". "Fluently" is a long adverb, so it should be "more fluently", not "fluenter".
Adverb
- ✅ She sings beautifully — ❌ She sings beautiful
- ✅ He drives carefully — ❌ He drives careful
- ✅ They arrived late — ✅ a late train (same form, both roles)
- ✅ She works hard — ❌ She works hardly (different meaning!)
The -ly words are adverbs — they modify verbs, adjectives, or other adverbs, telling you how, when, where, or to what degree.
Pattern: most adjectives become adverbs by adding -ly, but watch the exceptions — fast, hard, late, well — that keep the same shape or change meaning entirely.
Comparative and superlative
- ✅ She is taller than me. — ❌ She is more taller than me. (double comparative)
- ✅ This is the most interesting book. — ❌ This is the interestingest book.
- ✅ He did better than expected. — ❌ He did more good than expected. (irregular)
- ✅ That's the worst idea ever. — ❌ That's the baddest idea ever.
Comparatives compare two things (-er or more); superlatives pick the extreme of three+ (-est or most). Short adjectives use -er/-est; longer ones use more/most. Never combine both.
Rule: one or two syllables → -er/-est (with exceptions). Three+ syllables → more/most. Irregulars (good/better/best, bad/worse/worst) must be memorised.
A2 | Elementary | Pre-intermediate
- ✅ I went to the cinema yesterday. — past simple
- ✅ I have visited Paris twice. — present perfect (life experience)
- ✅ If it rains, I'll take an umbrella. — first conditional
- ✅ You should see a doctor. — modal for advice
These patterns are A2 — the second CEFR level. At A2 you move past survival phrases into real grammar: past tenses, the present perfect, basic conditionals, and modals for advice/obligation.
Marker: if you can describe yesterday and give simple advice, but struggle with abstractions or nuance, you're at A2.
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.
