The correct answers are Take these potatoes here and put them with those carrots over there. and Take this potato here and put it with that carrot over there.
This/These go with objects near you (indicated by the word "here").
That/Those go with objects far from you (indicated by the phrase "over there").
The incorrect options either mismatch the near/far words (using "those" for "here") or mismatch singular/plural grammar ("these potato").
Demonstrative
Demonstratives are pointing words: this, that, these, those. They tell the listener which one you mean — this and these point to things near you; that and those point to things further away (in space, time, or recent attention). They can sit before a noun (Put that coat on) or stand alone as a pronoun (Put that on).
Singular vs plural matches the noun: this book / these books. Mixing them up (these book) is one of the most-corrected slips for learners — small, but immediately noticeable.
Determiner
A determiner is a word that comes before a noun to clarify what it refers to: which one, how many, whose. The English determiners include articles (a, the), demonstratives (this, that), possessives (my, your), quantifiers (some, many, few), and distributives (each, every).
Most singular countable nouns in English require a determiner — I bought book is wrong; you need I bought a book or I bought the book. Determiner choice signals how much information you assume the listener already has, so getting it right shapes how natural your speech and writing sound.
English Grammar Basics
The English Grammar Basics tag marks quizzes and explainers covering the foundations of English grammar — nouns, verbs, adjectives, adverbs, prepositions, conjunctions, tenses, voice, mood, and basic sentence structure.
If you're starting out or rebuilding from scratch, this is the tag to follow: every challenge under it is designed to land the core rules without burying you in exceptions. Get the basics solid here and the more advanced topics — conditionals, reported speech, inversion — stop looking like a wall of new rules and start looking like extensions of what you already know.
A2 | Elementary | Pre-intermediate
A2 is the elementary level in the CEFR framework, sitting between A1 and B1. At A2 you can handle routine exchanges — ordering food, asking directions, making small talk — and describe your immediate environment in simple sentences.
Grammatically, A2 introduces past simple and past continuous, present perfect for experiences, basic modal verbs, and the first conditional. You're also picking up collocations and learning which verbs take gerunds vs. infinitives. Knowing your level here is the difference between confident progress and frustration: A2 material consolidates the basics; B1 will overwhelm you.
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.
