Respuesta correcta: A)are
💡 Explicación
When a quantifier such as some is followed by a plural noun, the verb agrees with that noun and takes the plural form. The choice of quantifier and the choice of verb are two separate decisions that students often confuse.
Ver respuesta
Respuesta correcta: A)are
A)areCorrect! 'Some' follows a plural noun, so the verb must be 'are', and the quantifier states that a limited number of chairs remains.
B)isNo. 'is' is singular and 'chairs' is a plural noun, so the sentence would break the agreement between subject and verb.
C)haveNo. 'have' is the auxiliary of the perfect tenses and has no plural agreement here; the simple present needs a form of 'be'.
D)hasNo. 'has' is singular and belongs to the third person of the present perfect, which is not the structure of this sentence.

Respuesta correcta: D)were
💡 Explicación
Any is the quantifier used in questions and in negatives, because it points to an unknown quantity. With a plural noun it takes a plural verb, so the interrogative clause reads there were any tickets rather than there was any ticket.
Ver respuesta
Respuesta correcta: D)were
A)wasNo. 'was' is singular and 'tickets' is plural, so the agreement between the verb and the quantified noun is broken.
B)isNo. 'is' is the singular present form and does not agree with a plural noun in any tense.
C)has beenNo. 'has been' is a passive auxiliary and there is no passive construction in this sentence about how many tickets remain.
D)wereCorrect! In a negative or interrogative clause 'any' is used, and with the plural noun 'tickets' the verb is the past plural 'were'.
💡 Explicación
Any is the quantifier used in questions and in negatives, because it points to an unknown quantity. With a plural noun it takes a plural verb, so the interrogative clause reads there were any tickets rather than there was any ticket.

Respuesta correcta: A)much
💡 Explicación
Countable and uncountable nouns take different quantifier families: many, few and a few for countable, much and little for uncountable. Choosing the right family is what makes the sentence acceptable in both affirmative and negative contexts.
Ver respuesta
Respuesta correcta: A)much
A)muchCorrect! 'Much' is the quantifier for uncountable nouns, and in a negative clause it strengthens the sense of absence.
B)manyNo. 'Many' is used with countable plural nouns, and 'time' here is uncountable, so 'many' cannot appear in front of it.
C)a fewNo. 'A few' quantifies countable plural items such as chairs or tickets, and 'time' is not countable in this use.
D)a littleNo. 'A little' quantifies a small positive amount, and the negative context of the sentence makes it inconsistent.

Respuesta correcta: A)How many
💡 Explicación
Interrogative quantities are formed with how plus a quantifier: how many for countable plurals and how much for uncountable nouns. They always begin the question and they never change form to agree with the noun that follows.
Ver respuesta
Respuesta correcta: A)How many
A)How manyCorrect! 'How many' is the interrogative quantifier for countable plural nouns, and it is written as two words at the start of the question.
B)MuchNo. 'Much' quantifies uncountable nouns and cannot stand in front of a countable plural such as 'students'.
C)FewNo. 'Few' is not used to open a direct question about a quantity; English uses 'how many' in that slot.
D)LittleNo. 'Little' quantifies an uncountable noun and has no plural form, so it cannot agree with 'students'.

Respuesta correcta: B)is little
💡 Explicación
Uncountable nouns take a singular verb because a mass noun is treated as a single unit for agreement. The quantifier that goes with it comes from the little family, and the same noun would also accept much or a little in other contexts.
Ver respuesta
Respuesta correcta: B)is little
A)are littleNo. 'are' is plural and would not agree with the singular mass noun 'water', which is treated as one thing.
B)is littleCorrect! With the uncountable noun 'water' the singular verb 'is' is used, and 'little' marks a very small quantity.
C)is fewNo. 'Few' belongs to the countable family and cannot quantify an uncountable noun such as water.
D)are fewNo. The noun is uncountable and the verb is plural here, so both decisions are wrong at once.

Few and a few differ in judgement rather than in grammar. Both take plural nouns, but few suggests the quantity is disappointingly small while a few suggests it is satisfactory, and the context decides which one the speaker intends.
Ver respuesta
Respuesta correcta: C)few
A)muchNo. 'much' quantifies uncountable nouns and 'opportunities' is a countable plural, so the quantifier belongs to the wrong family.
B)a fewNo. 'a few' marks a small positive number, and the sentence is about a situation where almost none were available.
C)fewCorrect! 'Few' with a plural noun is negative in meaning, and it agrees here with the plural 'opportunities' that follows it.
D)littleNo. 'little' quantifies an uncountable noun and cannot stand in front of a countable plural.

Respuesta correcta: C)How much
💡 Explicación
Choosing between how many and how much depends entirely on the noun that follows. Words such as equipment, information, furniture and advice are uncountable even when they look like plurals, so they take how much.
Ver respuesta
Respuesta correcta: C)How much
A)How manyNo. 'How many' is used with countable plural nouns, and 'equipment' is uncountable in this sentence.
B)How longNo. 'How long' asks about duration or length, and the sentence asks about a price.
C)How muchCorrect! 'How much' is the interrogative quantifier for uncountable nouns, and 'equipment' behaves as one mass noun here.
D)How farNo. 'How far' asks about distance, which has nothing to do with the cost of the equipment.

Abstract nouns such as experience, knowledge, advice and progress are uncountable and take the little and much family. The intensifier 'very' strengthens the sense of scarcity without changing the grammatical category of the quantifier.

Respuesta correcta: D)little
A)fewNo. 'Few' requires a plural countable noun, and 'experience' here is an uncountable mass noun.
B)manyNo. 'Many' also requires a plural countable noun and cannot quantify an abstract mass noun such as experience.
C)a fewNo. 'a few' suggests a small but sufficient number, and the sentence says he has hardly any experience at all.
D)littleCorrect! 'Little' quantifies an uncountable noun and, with 'very' before it, marks an amount close to zero.

A lot of and lots of are the most flexible quantifiers in English because they accept countable and uncountable nouns alike. They are often preferred in speech to many and much, and they need no adjustment of the verb that follows.
Ver respuesta
Respuesta correcta: C)lot
A)manyNo. 'many' requires a plural countable noun, and 'equipment' is uncountable, so the phrase cannot be built this way.
B)fewNo. 'a few of' would need a plural noun and would also suggest a small quantity, which is the opposite of what the sentence reports.
C)lotCorrect! 'A lot of' works with both countable and uncountable nouns, and here it modifies the uncountable noun 'equipment'.
D)littleNo. 'a little of' would suggest a small amount of an uncountable noun, and the verb 'bought' points to a large acquisition.

None, all, most, some and half are the quantifiers that accept an of phrase followed by a plural noun. They keep their own grammatical number when used alone, but inside the of phrase they agree with the plural noun and the verb of the sentence.
Ver respuesta
Respuesta correcta: A)None
A)NoneCorrect! 'None of' takes a plural noun phrase and agrees with the plural passive 'had been answered', stating that not one complaint was dealt with.
B)NeitherNo. 'Neither' is used for two items and takes a singular verb, whereas the sentence refers to an open set of complaints.
C)AllNo. 'All of' would state the opposite, because it says that every complaint had been answered before the council spoke.
D)Few of the complaintNo. 'few of' would need a plural noun inside the phrase, and the verb here is passive, so a smaller but non-zero number is what the option claims.

In the there is or there are construction the verb agrees with the noun that follows the quantifier, not with the pronoun 'there'. Any in a negative clause points to an expected quantity that turns out to be absent, which is why it goes with the plural verb here.
Ver respuesta
Respuesta correcta: B)aren't
A)isNo. 'is' is singular and 'students' is a plural noun, so the verb and the quantified noun would not agree.
B)aren'tCorrect! The negative contraction 'aren't' agrees with the plural 'students' and suits the negative context in which 'any' appears.
C)are someNo. 'some' is not used in a negative clause that denies the existence of the items, and the verb does not agree with it here.
D)weren'tNo. 'weren't' is the negative past, and the sentence refers to the present moment with the expression 'at this hour'.
