Advanced Determiner-Noun Agreement: correct answers
Jump to answers ↓Advanced Determiner-Noun Agreement
Determiners must perfectly match the nouns they modify, but advanced English rules often defy expectations. For example, the formal expression "many a" requires a singular noun and verb (e.g., many a student has), while "another" can surprisingly precede a plural noun if a number is included (e.g., another three weeks).
This challenge tests your ability to navigate these complex agreement rules. You will practice pairing demonstratives with irregular plurals like phenomenon vs. phenomena, choosing between amount and number based on countability, and correctly modifying tricky uncountable nouns like furniture, research, and equipment.
You'll work through 10 questions in a varied mix of single-choice, multi-choice, drop-down, and drag-and-drop formats.

Correct answers
Question 1
much / furniture / amount / equipment
much: The verb "is" indicates we are dealing with a singular/uncountable subject, so we use the uncountable quantifier "much".
furniture: This is an uncountable noun. "Furnitures" is grammatically incorrect. While "furnishings" is a valid plural word, it would require the verb "are" and the determiner "many".
amount: We use "amount" because the following noun is uncountable.
equipment: This is an uncountable noun that never takes an "-s" to become plural. It correctly pairs with the singular verb "is".
Question 2
Help the weary detective complete his dramatic memoir by choosing the grammatically correct phrase.
Over my thirty years on the police force, _____ attempted to outsmart the legendary Inspector Whiskers, only to fail miserably.
The correct answer is many a criminal mastermind has.
The formal determiner phrase "many a" is used to refer to a large number of people or things, but it strictly requires a singular countable noun and a singular verb (e.g., "many a mastermind has").
Question 3
Help the eccentric professor complete his grant renewal application by choosing the correct words for each blank.
I am requesting another ten thousand dollars for my research. It is true that many a brilliant student has accidentally turned invisible in my lab. Because of these unfortunate rumors, we received fewer applications this semester. However, science requires sacrifice!
Correct Answers:
I am requesting another ten thousand dollars for my research. It is true that many a brilliant student has accidentally turned invisible in my lab. Because of these unfortunate rumors, we received fewer applications this semester.
another + plural amount: While "another" usually precedes a singular noun, it is used before plural nouns when they represent a single unit of measurement, time, or money (e.g., "another ten thousand dollars").
many a + singular noun: The advanced determiner phrase "many a" takes a singular countable noun and a singular verb ("student has"), even though it refers to a large number of people or things.
fewer + plural countable noun: "Applications" is a plural countable noun, so we must use "fewer" rather than "less" (which is used for uncountable nouns). The word "form" is singular and doesn't fit the plural requirement of "fewer."
Question 4
The correct answers are Many a dusty scroll has been deciphered in this laboratory. and A great number of dusty scrolls have been deciphered in this laboratory.
"Many a" is an advanced, slightly formal construction that takes a singular countable noun and a singular verb (e.g., Many a scroll has...).
"A great number of" correctly pairs with plural countable nouns and plural verbs (e.g., A great number of scrolls have...).
"Amount" is used for uncountable nouns (like water or courage), not countable nouns like scrolls.
Question 5
Select the grammatically correct phrase for the paranormal researcher's presentation slide.
If you look closely at the blurry footage, it becomes quite clear that _____ cannot be explained by conventional science.
The correct answer is these strange phenomena.
"Phenomena" is an irregular plural noun (the singular form is "phenomenon"). Because it is plural, it must agree with a plural demonstrative determiner like "these" or "those".
Question 6
Help the stressed wedding planner finish her angry email to the venue manager by choosing the correct determiners and nouns for each blank.
I explicitly told the band that this heavy equipment is strictly prohibited near the pool. Furthermore, every bridesmaid has complained about the slippery floors. To make matters worse, there is entirely too much luggage blocking the fire exit!
Correct Answers:
I explicitly told the band that this heavy equipment is strictly prohibited near the pool. Furthermore, every bridesmaid has complained about the slippery floors. To make matters worse, there is entirely too much luggage blocking the fire exit!
this equipment: "Equipment" is an uncountable noun. It cannot be pluralized (no "equipments") and it requires a singular determiner ("this") and a singular verb ("is"). If you chose "these instruments," the singular verb "is" later in the sentence would be grammatically incorrect.
every bridesmaid: The verb "has" is singular, which means we need a singular subject. "Every" is a distributive determiner that pairs with a singular countable noun ("bridesmaid"). "All bridesmaids" or "both guests" would require the plural verb "have."
much luggage: "Luggage" is an uncountable noun. It cannot be pluralized (no "luggages") and it takes the uncountable quantifier "much" along with a singular verb ("is"). Choosing "many suitcases" would incorrectly clash with the singular verb "is" earlier in the clause.
Question 7
Choose the correct phrase to complete the eccentric inventor's frantic demands.
I am on the brink of a scientific breakthrough! I just need _____ to calibrate the flux capacitor.
The correct answer is another three weeks.
Usually, the determiner "another" is only used with singular nouns. However, as an exception, we can use "another" before a plural noun if it is preceded by a number or a quantifier (like "few"). This treats the phrase as a single, collective unit of time, distance, or money.
Question 8
this / phenomenon / number / criteria
this: The verb "was" is singular, so we need the singular demonstrative determiner "this".
phenomenon: This is the singular form of the noun (of Greek origin). "Phenomena" is plural, and "phenomenons" is incorrect.
number: Because the following noun is countable, we must use "number" rather than "amount" (which is for uncountable nouns).
criteria: This is the plural form of "criterion" (Latin origin). Since we are talking about a "number of" them, it must be plural.
Question 9
The correct answers are No amount of persuasion will make the bride change her mind. and Any number of things could go wrong with the seating chart today.
The determiner "amount" is strictly used with uncountable nouns (like persuasion, stress, or water).
The determiner "number" must be used with plural countable nouns (like things, guests, or chairs). Mixing these up is a common error, but remembering whether you can physically count the noun will save the day!
Question 10
The correct answers are These criteria are essential for understanding the anomaly. and Much research has been conducted on this bizarre phenomenon.
"Criteria" is the plural form of the singular noun "criterion". Therefore, it must be paired with the plural demonstrative determiner "these" (not this).
"Phenomenon" is singular (plural: phenomena), so it correctly takes "this".
"Research" is an uncountable noun in English; it cannot be made plural (researches) and must be quantified with "much" rather than "many".
