Grammar Quiz

Question 1

Choose the correct sentence.

Use the indefinite article a before a singular countable noun mentioned for the first time. "Restaurant" is countable and non-specific here.

Question 2

Which is correct?

Singular countable nouns need an article. "Jacket" with no context → a jacket. (Use "the jacket" only if the listener already knows which one.)

Question 3

Fill in the blank. Choose the correct option.
"It's _____ total mess in here."

"Total mess" is a singular countable expression here → a total mess. "The" would imply a specific mess the listener already knows about.

Question 4

Choose the correct sentence.

"The last few years" is a specific, defined period — it refers to the years immediately before now. It always takes the.

Question 5

Which sentence is correct?

"Discussion" is a countable noun. Without a specific reference already established, use a discussion.

Question 6

Fill in the blank.
"When it comes to _____ current market situation, we need to be careful."

"The current market situation" refers to one specific, shared context both speakers understand → the. This is a very common omission in Polish-speaker English.

Question 7

Choose the correct word.
"There were _____ kids at the event than expected."

Fewer is used with countable nouns (kids, people, cars). Less is for uncountable nouns (time, money, water).

Question 8

Choose the correct word.
"The new subway lines will serve _____ passengers than expected in the first year."

"Passengers" is countable → fewer passengers. "Less" is only for uncountable quantities.

Question 9

Choose the correct option.
"There were _____ concerns from residents about the noise."

"Concerns" is a countable plural noun → many concerns. Use "much" only with uncountable nouns (e.g. "much confusion").

Question 10

Find the mistake and choose the correct version.
"He's had too much fails in his career."

Two errors: much → many (countable) and fails → failures. "Fail" is a verb; the noun form is "failure." Both B and C fix one issue — only B fixes both.

Question 11

Choose the correct embedded question.
"The app lets you select _____ ."

In embedded (indirect) questions, use statement word order — no inversion. ✓ how you watch (not "how do you watch").

Question 12

Which sentence is grammatically correct?

After "I don't know," use statement order (subject before verb): how solid the accusations are — not the inverted question form.

Question 13

Choose the correct sentence.

After a reporting verb like "know," the embedded question uses statement word order: what their problem is.

Question 14

A colleague asks: "Can you tell me what problem you are solving?"
Which version of this question is a direct (non-embedded) question?

Direct questions use inverted order (auxiliary before subject): What problem are you solving? The embedded version drops the inversion: "Can you tell me what problem you are solving?"

Question 15

Choose the correct preposition.
"I was _____ my cousin's wedding last weekend."

Use at for events and locations (at a wedding, at a conference, at a party). "On" is for surfaces, days, and media. "In" is for enclosed spaces.

Question 16

Choose the correct preposition.
"The whole sales team is _____ a trade show this week."

Trade shows, conferences, and events use at. ("On" a trade show is a common Polish-speaker error — think of "na targach" → but in English it's always "at.")

Question 17

Choose the correct preposition.
"_____ my opinion, we should pivot to a B2B model."

The fixed phrase is in my opinion — never "on my opinion." (Compare: Polish "moim zdaniem" can feel like "on," but English always uses "in.")

Question 18

Choose the correct preposition.
"He studied _____ Harvard for two years."

Institutions (universities, schools, companies) take at: at Harvard, at Google, at the university. "In" is used for cities/countries.

Question 19

Choose the correct form.

"Worth" is always followed by a gerund (-ing form): worth trying, worth doing, worth keeping. Never use "to + infinitive" after "worth."

Question 20

Which sentence is correct?

"Worth" + gerund: worth keeping. You can also say "it's worth it to keep…" — but "worth to keep" is always wrong.

Question 21

Choose the correct phrase.
"_____ I had a really productive meeting."

In English, we say this morning / this afternoon / this evening / tonight — never "today morning." "Today" stands alone: "I was busy today."

Question 22

Choose the correct phrase.
"He built the whole company _____ ."

The correct expressions are on his own or by himself. "By his own" is not a standard English phrase.

Question 23

Which sentence uses "research" correctly?

"Research" is an uncountable noun in English — it has no plural form. Say some research, not "some researches." For individual items: "a study," "several studies."

Question 24

The sentence has a verb tense error. Choose the correct version.
"I didn't know it exists."

When the main verb is past ("didn't know"), the subordinate clause must also be past: I didn't know it existed. This is called "sequence of tenses" or "backshift."
