Quantifiers with Of-Structures: correct answers
Jump to answers ↓Quantifiers with Of-Structures
When should you use "of" after a quantifier? If a quantifier is followed directly by a general noun, "of" is typically omitted (e.g., most humans). However, when the noun is restricted by a specific determiner like the, my, or this, or when you are using an object pronoun, the "of" structure becomes essential. For example, you must say most of the humans and every one of them.
In this challenge, you will navigate eccentric scenarios (from a weary wizard's potion tasting to a baffled lawyer reading a billionaire's will) while mastering these tricky grammar rules. You will practice forming correct structures using every one of, few of the, much of the, and neither of. The exercises also cover the subtle distinctions between no vs. none of the, and how to accurately pair quantifiers with plural, singular, and uncountable nouns.
You'll work through 10 questions in a diverse mix of single-choice, multi-choice, drop-down, and drag-and-drop formats.

Correct answers
Question 1
The correct answers are Every one of, Much of, and Few of.
Every one of: We cannot use every directly with a pronoun (e.g., "every them" is incorrect). We must use the structure every one of + pronoun.
Much of: Furniture is an uncountable noun. Because it is preceded by a specific determiner (the), we must use of after the quantifier (e.g., much of the, not much the).
Few of: Business partners is a plural countable noun preceded by the possessive determiner my. Therefore, we need of after the quantifier (e.g., few of my, not few my). We use few rather than a little because the noun is countable.
Question 2
Help the weary wizard complete his disastrous food review.
I have tasted thirty different enchanted cupcakes today, and to my absolute horror, ___ turned me into a different species of amphibian.
The correct answer is every one of them.
The quantifier "every" cannot be followed directly by "of". To use it with a pronoun like "them", you must add "one" to create the structure: every one of + pronoun.
"Each them" is missing the preposition "of", and "all of it" is incorrect because "cupcakes" is a plural countable noun.
Question 3
The correct answers are Many of the artifacts were recovered from the getaway vehicle, Most of the security cameras had been disabled, and None of them saw the culprit enter the vault.
When we use a quantifier (like many, most, some, none) followed by "of", the noun that comes after it MUST be preceded by a determiner (like the, my, those) or be an object pronoun (like them, us, it).
Therefore, "Many of artifacts" and "Most of security cameras" are incorrect because they lack a determiner (like "the") before the noun.
Question 4
Help the dramatic detective reveal the twist during the mansion interrogation.
Despite the billionaire's vast and notoriously expensive art collection, ___ paintings hanging in the grand hall were actually authentic originals.
The correct answer is few of the.
"Paintings" is a plural countable noun, so we must use "few" rather than "little".
Because the sentence refers to a specific group of paintings (the ones hanging in the grand hall), we need an of-structure. The strict grammatical rule is: quantifier + of + determiner (the/my/these) + noun. "Few of paintings" and "few the paintings" both violate this structural rule.
Question 5
The correct answers are Very few of the guests have RSVP'd on time, Much of the wedding cake was mysteriously eaten by the best man, and Several of my carefully arranged centerpieces were knocked over.
Quantifiers must match the countability of the noun phrase they refer to, even when separated by "of".
- Few / Several / Many are used with plural countable nouns (e.g., few of the guests, several of my centerpieces).
- Little / Much are used with uncountable nouns (e.g., much of the wedding cake).
"Very little of the guests" and "Much of the bridesmaids" are incorrect because guests and bridesmaids are countable nouns.
Question 6
The correct answers are Neither of, Most of, and None of.
Neither of: When a quantifier is followed by a pronoun (them), we must use of. Since there are exactly two ovens, neither of is the correct negative choice.
Most of: When a noun is modified by a specific determiner (like the, my, this), the quantifier must be followed by of. We cannot say "most the ingredients"; it must be "most of the ingredients".
None of: Similar to the previous rule, excuses is modified by the possessive determiner your. We cannot say "no your excuses" or "none your excuses". The correct structure is none of + determiner + noun.
Question 7
Help the detective complete his final report on the bizarre museum heist by choosing the correct quantifier for each blank.
The inspector noted that the thieves left no fingerprints behind, and strangely, they triggered none of the alarms on their way out. He interrogated the night guards and quickly found that every one of them was hiding something. To make matters worse, it seems that a great deal of the stolen artwork is already overseas.

He interrogated the night guards and quickly found that every one of them was hiding something. To make matters worse, it seems that a great deal of the stolen artwork is already overseas.
no is a determiner used directly before a noun ("no fingerprints"). We cannot use "none of" without a determiner like "the" or "my".
none of the is required because "alarms" is preceded by the specific determiner "the".
every one of is used before pronouns like "them". We cannot say "every of them" or "every them".
a great deal of is used with uncountable nouns like "artwork". "A large number of" is only used with plural countable nouns.
Question 8
The correct answers are Both of my eyebrows were singed off by the blast, Half the laboratory is covered in green slime, and All of the bubbling potions evaporated instantly.
With the quantifiers all, both, and half, the word "of" is optional when followed by a noun phrase with a determiner (e.g., Half the laboratory OR Half of the laboratory).
However, there are two strict rules:
- If you use a pronoun, you must include "of" (e.g., All of them, NOT All them).
- If you use "of" before a noun, you must include a determiner like "the" or "my" (e.g., Half of the laboratory, NOT Half of laboratory).
Question 9
Complete the dramatic botanist's journal entry about her disastrous jungle expedition by choosing the correct phrase for each blank.
We spent much of the expedition walking in circles. We quickly realized that few of our maps were actually accurate for this region. Because of the endless rain, very little of the original equipment survived the trek. Our guide finally confessed that all of us were hopelessly lost.
We spent much of the expedition walking in circles. We quickly realized that few of our maps were actually accurate for this region. Because of the endless rain, very little of the original equipment survived the trek. Our guide finally confessed that all of us were hopelessly lost.
much of the is used because "expedition" is singular, referring to a single block of time/event. "Many" would require a plural noun.
few of our is used because "maps" is a plural countable noun preceded by a possessive determiner ("our").
little of the is used because "equipment" is an uncountable noun. We need "of" because it is followed by the determiner "the".
all of us is the correct structure before an object pronoun. "All us" is non-standard, and "every of us" is grammatically incorrect.
Question 10
Complete the alien spy's observation log about Earthlings.
While general human behavior is baffling enough, ___ I have observed at this particular coffee shop seem utterly addicted to boiling hot roasted bean water.
The correct answer is most of the humans.
When referring to a specific, restricted group (the humans at this particular coffee shop), we must use most of the + noun (or another determiner like these or my).
"Most humans" is used for general statements about the entire species. "Most of humans" is grammatically incorrect because "of" must always be followed by a determiner or a pronoun.
