Help the food critic finish her review of a highly unusual cooking competition by choosing the correct sentence adverb for each gap.
The addition of bitter cigar ash, paradoxically, made the chocolate cake taste incredibly sweet and complex. The dessert was ostensibly a centuries-old family recipe, though the judges suspected the chef had simply panicked and improvised on the spot. Ultimately, the resulting mess was undeniably the best thing the panel had ever tasted, given their unanimous perfect scores.
The addition of bitter cigar ash, paradoxically, made the chocolate cake taste incredibly sweet and complex.
"Paradoxically" is used because adding something bitter to make something sweet is a contradiction or paradox.
The dessert was ostensibly a centuries-old family recipe...
"Ostensibly" means apparently or purportedly, but perhaps not actually. It perfectly fits a situation where someone claims one thing, but others suspect the truth is different.
Ultimately, the resulting mess was undeniably the best thing the panel had ever tasted...
"Undeniably" means it cannot be denied. The "unanimous perfect scores" serve as irrefutable proof.
Adverb
An adverb modifies a verb, an adjective, or another adverb — adding information about how, when, where, how often, or to what degree something happens: she sings beautifully, unbelievably fast, we go there often. Many adverbs end in -ly, but plenty don't (well, fast, hard, almost).
Adverbs matter because they're how you add nuance without piling on extra clauses. Used well, a single adverb can sharpen a vague sentence (she answered → she answered honestly), but misplace one and the meaning drifts in a way native speakers immediately notice.
Sentence
A sentence is the largest grammatical unit in writing — one or more clauses expressing a complete thought, ending with a period, question mark, or exclamation mark. English sentences come in four structural types: simple (one independent clause), compound (two or more independent clauses joined), complex (independent + dependent clause), and compound-complex (multiple independent + dependent clauses).
Mastering sentence types is what lets you vary rhythm in writing. All-simple sentences read as choppy; all-complex sentences read as dense. Mixing them is what makes prose breathe.
Word Order
Word order is the sequence in which words appear in a sentence. English is fundamentally an SVO language — subject, verb, object (Kate loves Mark). The order of adjectives, adverbs, and modifiers within a noun phrase also follows fixed patterns (a small red wooden box, not a wooden red small box).
In English, word order carries grammatical meaning — change the order and you change the sentence. The dog bit the man and The man bit the dog differ only in word order, but the meaning flips entirely.
C1 | Advanced
C1 is the advanced level in the CEFR framework, sitting between B2 and C2. At C1 you stop translating in your head and start thinking in English — handling specialised articles outside your field, picking up implicit meaning, and writing structured arguments on complex topics.
Grammatically, C1 means natural use of inversion (Rarely have I seen…), mixed and advanced conditionals, subjunctive forms in formal contexts, and cleft sentences for emphasis. Most university programmes for non-native speakers and many professional certifications set C1 as their entry standard.
Difficulty: Hard
The Hard difficulty tag marks questions and challenges aimed at upper-intermediate to advanced learners — typically B2 and above. Expect interacting rules, edge cases, distractors that look right at first glance, and contexts where the surface meaning and the grammatical answer don't match.
Filter by Hard when you're past the basics and want material that genuinely tests your understanding. These questions catch the gaps your textbook didn't — register-sensitive choices, exception cases, mixed conditionals, the difference between would have been and had been.
