The correct answer is "did". In this question, we are asking about the time a past action happened for a singular subject, so we use "did" as the auxiliary verb for simple past questions.
Questions
Questions in English are typically formed by inverting the subject and an auxiliary verb: She can dance → Can she dance?. When there's no auxiliary present, English adds do-support: The milk goes in the fridge → Does the milk go in the fridge?. The same pattern handles wh-questions (Where do you live?) and negative questions (Doesn't he know?).
The trickiest variant is indirect questions — I wonder where he is, not where is he. The inversion drops because the question is embedded inside another clause. Getting this right is one of the bigger jumps from A2 to B1 fluency.
Auxiliary verb
An auxiliary verb (or "helping verb") is a verb that combines with a main verb to add grammatical meaning — questions, negation, tense, aspect, voice, or modality. The English auxiliaries are forms of be, have, do, plus the modal verbs (can, could, will, would, should, may, might, must).
Auxiliaries are what let you build past tense (have gone), continuous aspect (is going), passive voice (was eaten), and questions (Do you know?). Without them, you can't form most of the structures you need beyond the simple present and past — they're the engine that powers half the tense system.
Adjunct
An adjunct is a part of a sentence — usually a phrase giving extra information about time, place, manner, or reason — that you can remove without breaking the sentence. In John helped Bill in Central Park, the phrase in Central Park is an adjunct: drop it and John helped Bill still works as a complete sentence.
Recognising adjuncts versus arguments (the parts a verb actually needs) helps you understand why some elements are obligatory and others are optional — useful for spotting where commas belong and where a sentence can be tightened or expanded.
A1 | Elementary | Beginners
A1 is the starting level of the CEFR framework — the entry point into English. At A1 you can introduce yourself, ask and answer simple personal questions, recognise common signs and instructions, and have short slow-paced conversations on very familiar topics.
Grammatically, A1 covers the building blocks: present-tense forms of be, have, and do; basic word order; simple questions; and the most common determiners, pronouns, and prepositions. Knowing your level matters — A1 material teaches the foundations every later level builds on, while a B1 textbook will overwhelm you. Start here and progress is fast.
Difficulty: Easy
The Easy difficulty tag marks questions and challenges aimed at beginners — typically A1 or early A2 level. Expect single-rule focus, short sentences, common everyday vocabulary, and one clear correct answer. Distractors usually rule themselves out quickly.
Filter by Easy when you're rebuilding fundamentals, warming up before harder material, or testing whether you've truly internalised a basic rule before moving on. Easy doesn't mean trivial — it means the rule itself is unambiguous and the context doesn't pile on extra complications.
