The correct answers are I will explain the schedule to everyone., Please listen to the driver carefully., and I have some important information for you.
Explain: You cannot "explain someone something" in English. You must "explain something to someone." This is a tricky difference from German (jemandem etwas erklären) and French (expliquer quelque chose à quelqu'un).
Listen to: The verb listen requires the preposition to when there is an object, unlike the French écouter.
Information: In English, information is an uncountable noun. It never takes an "s" at the end, even when referring to multiple facts (unlike French informations or German Informationen).
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.
Countable and uncountable
In English, nouns split into two groups based on whether you can count them. Countable nouns (chair, book, idea) take a/an, form plurals (chairs), and pair with many, few, several. Uncountable nouns (water, furniture, advice, information) take no article in their general sense, have no plural, and pair with much, little, some.
This distinction matters because it controls article choice, plural marking, verb agreement, and quantifier selection — fewer chairs vs less water, an advice (wrong) vs some advice. It's one of the most common error sources for learners from languages without this split.
B1 | Intermediate
B1 is the intermediate level in the CEFR framework — the point where you stop relying on memorised phrases and start handling everyday English independently. At B1 you can describe experiences, explain opinions, and follow most clear standard speech on familiar topics like work, travel, and hobbies.
Grammatically, B1 means combining tenses with precision, building complex sentences, and starting to use passive voice, modal verbs for necessity and possibility, and verb patterns (gerund vs. infinitive). Knowing your level shapes what you study next: pushing too far ahead frustrates you; staying below your level wastes time.
Difficulty: Medium
The Medium difficulty tag marks questions and challenges in the middle of the difficulty range — typically suitable for A2 to B1 learners. Expect a single rule with realistic distractors, longer sentences, and contexts where you have to think before answering rather than reading off the obvious choice.
Filter by Medium when you're past the absolute basics and ready to consolidate. It's the level where most lasting progress happens — easy enough that you can finish without exhausting concentration, hard enough that getting it right means you've actually understood.
