English Grammar: Subject-Verb Agreement and Sentence Completion

In 'one of those women who...', the relative pronoun 'who' refers to 'women' (plural), requiring the plural verb 'run'. Also, 'their' correctly refers back to the women. This is a classic subject-verb agreement trap with 'one of those'.

The subject is 'service' (singular uncountable noun), so it requires the singular verb 'makes'. The restaurant is just a prepositional phrase modifying service - singular subjects take singular verbs regardless of intervening phrases.

The subject is 'income' (singular), so 'has' is correct. 'Of many small businessmen' is just a prepositional phrase that doesn't affect the verb. Even with intervening phrases, singular nouns need singular verbs.

With 'neither...nor', the verb agrees with the subject nearest to it. 'President' is singular, so 'is' (singular) is correct. This is the proximity rule for neither/nor constructions.

With 'kind of', the demonstrative must match the number of 'kind' (singular). So 'That kind' is correct, not 'These kind' or 'Those kind'. 'Them kind' is grammatically incorrect. The phrase following (of apple) doesn't change the rule.

With fractions and partitives like 'three-quarters of', the verb agrees with the noun in the 'of' phrase. 'Work' is singular (uncountable), so the singular verb 'is' is correct. The fraction doesn't determine plurality - the noun after 'of' does.

With 'two-thirds of', the verb agrees with 'pupils' (plural countable noun), so 'were' (plural) is correct. The fraction itself doesn't determine plurality - the noun following 'of' does. This is the opposite pattern from the previous question.

With 'either...or' constructions, the verb agrees with the nearest subject. Here, 'parents' is plural and comes right before the verb, so we use the plural verb 'have' rather than 'has,' 'was,' or 'is.' The phrase 'either his sister or his parents' means only one group is coming, but the verb matches 'parents.'

Phrases like 'as well as' don't work like 'and' to make plural subjects. The verb must agree with the first subject only. George Bernard Shaw is one person (singular), so we need 'was,' not 'were.' The correct form is 'George Bernard Shaw, as well as Mahatma Gandhi, was a vegetarian.'

After 'as if' or 'as though' when describing an unreal or hypothetical situation, we use the subjunctive mood 'were' instead of 'was.' This shows the situation isn't real: she isn't actually being murdered. The correct form is 'She screamed as if she were being murdered.'

This is a mixed conditional sentence. The first clause uses the subjunctive 'were not' for a present unreal condition (she actually is stupid), while the result clause uses 'would have understood' for a past consequence that didn't happen. This combination shows a present trait causing a past missed opportunity.

This is a third conditional sentence describing an unreal past situation. We use the past perfect 'had gone' in the if-clause and 'would have felt' in the result clause. This means he didn't actually go to the party, and as a result, he didn't feel better.

This is a third conditional about an unreal past event. 'Had been' (past perfect) in the if-clause and completes with 'have countenanced' to form 'would not have countenanced' in the result clause. It means he was home that night, so he did tolerate those shenanigans (the opposite of what the conditional states).

'Each one of' is a singular subject, even when followed by a plural noun like 'children.' The verb must be singular to match 'each one.' Therefore, 'speaks' is correct, not 'speak.' The phrase emphasizes every individual child separately.

This is a first conditional expressing a possible future situation. 'If I ever become' uses present tense for the condition, and 'I would weed out' expresses the hypothetical result. The word 'ever' emphasizes the possibility. This type of conditional talks about real or likely future scenarios.

In 'one of the [plural noun]' constructions, the subject is 'one,' which is singular. The verb must agree with 'one,' not with the plural noun. Therefore, 'One of the many galaxies was proved' is correct with the singular verb 'was.' The relative clause 'that proved to be near a black hole' describes which galaxy.

'Every' distributes to each item individually, so even when multiple nouns are joined by 'and' after 'every,' the subject remains grammatically singular. 'Every possible cause and suspect' means each cause and each suspect separately, so the singular verb 'was' is required, not 'were.'

'Everyone' is a singular indefinite pronoun, so it requires a singular possessive pronoun. Traditionally, 'his' serves as the gender-neutral singular possessive. While modern usage sometimes prefers 'his or her,' in formal grammar 'his' alone is acceptable as the traditional neutral form.

It is plural of alumna meaning young women who are graduates or former students of a specific school, college, or university.

'Time and tide' is a compound subject with two nouns, so it takes the plural verb 'wait,' not 'waits.' This proverb means that neither time nor the changing circumstances of life stop for anyone. The plural form emphasizes that both time and tide are distinct forces that don't wait.

The subject 'All I want' functions as a singular noun phrase because the core subject is 'I' (first person singular). In present tense, 'I want' agrees with 'is', not 'are' or 'were'. The phrase 'All I want' means 'everything that I desire', which is a singular concept.

The phrase 'a series of' is a collective noun phrase that takes a singular verb. Even though 'sightings' is plural, the true grammatical subject is 'series' (singular). This is why 'has' (singular) is correct, not 'have' (plural).

Academic discipline names ending in '-ics' (economics, physics, mathematics) take singular verbs when referring to the field of study itself. When referring to plural specific phenomena, they might take plural verbs, but here it's clearly the discipline, so 'is' is correct.

The main subject is 'The depletion' (singular). Phrases starting with 'in addition to' are parenthetical and don't change the number of the subject. Therefore, the verb must be singular 'has', not plural 'have'. 'Would' and 'could' are grammatically incorrect - present perfect 'has encouraged' is the right tense.

The true subject is 'Your blood pressure' (singular). The phrase 'as well as your temperature and heartbeat' is additive but doesn't make the subject plural. Therefore, the verb must agree with the singular 'blood pressure', taking 'is' not 'are'. 'Was/were' are wrong because the context suggests current state ('today').
