The correct answers are Who betrayed you during the island challenge? and Who did you betray during the island challenge?
Both of these are correct, but they ask very different things!
- Subject Question: "Who betrayed you?" (We don't know the subject. No auxiliary "did" is needed when who is the subject doing the action.)
- Object Question: "Who did you betray?" (You are the subject, so we need the auxiliary "did" before the subject.)
- "Who did betrayed you?" is incorrect because we don't use "did" with a past tense verb ("betrayed").
- "Who you betrayed?" is missing the auxiliary "did."
Questions
If you've ever asked You like coffee? with rising intonation and gotten a confused look — you've felt the gap between casual and grammatical English questions. Many languages form questions with intonation alone, but English usually requires inversion (Are you ready?) or do-support (Do you like coffee?). Skip the structure and your questions sound like uncertain statements.
Questions in English use inversion of subject and an auxiliary (Can she dance?) or do-support when no auxiliary is present (Does the milk go in the fridge?). Yes/no questions, wh-questions, negative questions, and tag questions all share this machinery.
Interrogative sentence
If you've ever asked You like coffee? with rising intonation and gotten a confused look — you've hit the gap between casual and grammatical English questions. Plenty of languages form questions just by changing intonation, but English usually requires inversion or do-support. Pick the right structure and your questions sound natural; skip it and they sound like statements with a hopeful tone.
An interrogative sentence asks a question, ending with a question mark: What do you want? / Are you ready?. English questions use inversion (subject swaps with an auxiliary verb) or do-support (Do you know?). They split into yes/no questions and wh-questions.
English Grammar Basics
If grammar feels like a tangle of rules you can never quite remember, the fix isn't more advanced material — it's making the foundations automatic. The English Grammar Basics tag is where you do that: the building blocks every other topic stands on. Get these right and the rest stops feeling random.
It marks quizzes and explainers covering the core of English: nouns, verbs, adjectives, adverbs, prepositions, conjunctions, tenses, voice, mood, and basic sentence structure. Useful whether you're a beginner or refreshing rusty knowledge.
Humor
If you've ever reached the third drill of present perfect and felt your eyes glaze over, you've hit the limits of dry repetition. Practice that's even mildly funny is far easier to come back to — and far easier to remember weeks later. That's the whole point of the Humor tag.
The Humor tag marks questions where the author has tried to make the practice entertaining alongside instructive. Subjective, sometimes silly, but designed to keep you engaged long enough for the rule to stick.
A2 | Elementary | Pre-intermediate
If you can order coffee, ask for directions, and tell someone what you did yesterday — but struggle the moment the conversation drifts into anything abstract — you're operating at A2. Knowing this matters: A2 is the level where most learners plateau because they reach for B2 material too early and burn out. Stay here and your foundations get unbreakable.
A2 is the elementary level in the CEFR framework, covering routine communication and the first wave of real grammar: past simple and continuous, present perfect, basic modal verbs, first conditional, and common verb-pattern rules.
Difficulty: Easy
If a textbook leaves you confused, sometimes the issue isn't the topic — it's that the practice material is layered with extra complications. Filtering by Easy strips that away. You get one rule at a time, in plain everyday language, with no trick questions. It's how you make a shaky foundation solid before stacking more on top.
The Easy difficulty tag marks beginner-level questions and challenges — typically A1 or early A2. Single-rule focus, short sentences, common vocabulary, one clear correct answer.
