Help an overly dramatic roommate complete their highly formal (and slightly ridiculous) complaint about the kitchen situation by choosing the correct discourse markers for each gap.
I acknowledge your contribution of the premium dish soap; be that as it may, leaving a lasagna pan to soak for three weeks is simply unacceptable.
I find your excuse of being "too busy" completely invalid, inasmuch as I watched you play video games for six hours straight yesterday.
The kitchen is finally clean, albeit smelling rather strongly of industrial bleach and passive-aggression.
I acknowledge your contribution of the premium dish soap; be that as it may, leaving a lasagna pan to soak for three weeks is simply unacceptable.
"Be that as it may" is a formal way of saying "despite that fact" or "nevertheless." It accepts the previous statement but introduces a contrasting point.
I find your excuse of being "too busy" completely invalid, inasmuch as I watched you play video games for six hours straight yesterday.
"Inasmuch as" means "since" or "because." It introduces the reason why the excuse is invalid. "Notwithstanding" (despite) and "nevertheless" (however) do not fit the logical cause-and-effect relationship here.
The kitchen is finally clean, albeit smelling rather strongly of industrial bleach and passive-aggression.
"Albeit" is a formal conjunction meaning "although" or "even though." It is used here to introduce a concession about the state of the clean kitchen.
Conjunction
Coordinating vs subordinating conjunction: coordinating (and, but, or) joins two elements of equal rank — clause + clause, noun + noun. Subordinating (because, although, if) makes one clause depend on the other. The test: remove the conjunction. If both halves still feel complete → coordinating. If one half collapses → subordinating.
Conjunctions are connecting words for clauses, phrases, and words. The choice between coordinating and subordinating determines whether you're building a compound or complex sentence.
Diagnostic: does the conjunction create a dependent clause? Yes → subordinating. Does it link equals? → coordinating.
Adverb
Adverb vs adjective: adjectives describe things; adverbs describe actions, qualities, or degrees. The mix-up usually happens after action verbs — she sings beautiful (wrong) vs she sings beautifully (right).
An adverb modifies a verb, adjective, or another adverb: incredibly fast, she spoke softly, we go often.
Diagnostic: ask what word is this describing? If it's a verb (an action) → adverb. If it's a noun (a thing) → adjective. Exception: linking verbs (be, seem, taste) take adjectives, not adverbs.
Complex sentence
Complex vs compound sentence: a compound sentence links two equal independent clauses with and/but/or. A complex sentence links an independent clause with a subordinate (dependent) clause — one idea is the main point, the other is background.
A complex sentence = independent clause + dependent clause. The dependent clause adds time (when), reason (because), condition (if), or detail (who/which).
Diagnostic: are both halves able to stand alone? Yes → compound. Can only one stand alone? → complex.
Semicolon
Semicolon vs colon vs period: semicolon = "these two independent thoughts are closely related" (I left; she stayed). Colon = "here's what I mean" — introduces (She had one goal: win). Period = complete separation. All three go between complete thoughts; the choice signals the relationship.
The semicolon (;) joins related independent clauses without a conjunction. Both halves must stand alone as sentences.
Diagnostic: are both sides independent clauses? AND are they closely related in meaning? Yes to both → semicolon. Is one explaining the other? → colon. No close relationship? → period.
C1 | Advanced
C1 vs C2: C1 means fluent and flexible use with occasional gaps in very unfamiliar domains. C2 means native-like command of idiom, irony, and register across any subject. If you can handle advanced grammar but still miss cultural nuance or very rare idioms, you're C1.
C1 is the advanced CEFR level: inversion, cleft sentences, subjunctive mood, advanced conditionals, and precise register control in professional and academic contexts.
Diagnostic: can you write persuasively in different registers and catch subtle irony? Consistently → C2. Sometimes → C1.
Hard
Hard vs Medium: Medium tests one rule with realistic distractors. Hard tests interacting rules, edge cases, or context-dependent answers where multiple options seem correct until you think deeply. If you're scoring 80%+ on Medium, try Hard to find your real gaps.
The Hard tag filters for B2+ challenges with layered difficulty: rule interactions, subtle distractors, and contexts that demand genuine grammatical reasoning.
Diagnostic: if Hard questions feel impossible, drop to Medium and master the individual rules first. Hard assumes you already know each rule — it tests whether you can apply them together.
