Help the disgruntled employee draft their formal resignation letter by choosing the correct prepositions.
Your insistence on micromanaging every trivial detail is tantamount ___ a complete lack of trust, and my current salary is hardly commensurate ___ the immense stress I endure daily.
The correct answer is to / with.
The adjective tantamount (meaning equivalent in seriousness to) is always followed by the preposition to.
The adjective commensurate (meaning corresponding in size or degree) pairs with the preposition with.
Preposition
A preposition is a small word that links a noun or noun phrase to other parts of the sentence — usually marking time, place, or relationship: in, on, at, to, from, with, over, under, between, during. The book on the table, We met at noon, She lives in Berlin.
Prepositions are deceptively small. Their meaning shifts dramatically by collocation (depend on, good at, afraid of), and their choice rarely translates directly between languages. Picking the right preposition is one of the trickiest, most idiomatic-sounding parts of English.
Adjective
An adjective is a word that describes a noun or pronoun — giving more information about its quality, state, or identity. Adjectives sit either before the noun (a tall building) or after a linking verb (The soup is hot), and they answer questions like what kind?, which one?, or how many?
Getting adjectives right matters for two everyday reasons: their position is fixed (you can't say a redly dress), and when you stack several before a noun, English follows a strict order — opinion, then size, then age, then colour. Break that order and the sentence sounds off even when each word is correct.
Collocations
Collocations are combinations of words that habitually occur together in a fixed order — make a decision (not do a decision), strong coffee (not powerful coffee), heavy rain (not thick rain). The grammar would allow either pairing, but native speakers consistently pick one and reject the other. Common patterns include verb + noun, adjective + noun, adverb + adjective, and adverb + verb.
Learning vocabulary as collocations rather than isolated words is the single fastest way to sound natural in English. It's the difference between I made a big mistake and I did a big mistake — small, but immediately noticeable.
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.
