Question 261Question →

In the sentence below, which pair of verb forms correctly completes the blanks?

'Neither the chief medical officer nor the consulting surgeons _____ pleased with how three-quarters of the emergency relief fund _____ disbursed by the executive committee.'

Show answer & explanation

Answer: were / was

Answer

The correct option is 'were / was'.
The option 'were / was' is correct because it follows two distinct rules of English concord: 1) In correlative structures using 'neither... nor', the verb agrees with the subject closest to it. Here, 'consulting surgeons' is plural, so the plural past verb 'were' is required. 2) When dealing with fractions such as 'three-quarters of', the verb matches the noun following 'of'. Because 'the emergency relief fund' is a singular entity, it takes the singular verb 'was'.

Step-by-Step Solution

1
Analyze the subject-verb structure of the first clause joined by 'Neither... nor'.
Under the rule of proximity concord, when subjects are connected by 'neither... nor', the verb must agree in number with the subject closer to it ('consulting surgeons').
Since 'consulting surgeons' is plural, the plural verb 'were' must be used.
2
Analyze the subject-verb structure of the noun clause containing a fractional expression.
When a fraction or percentage modifies a noun, the verb agrees with the noun following the preposition 'of' ('emergency relief fund').
Since 'fund' is a singular uncountable noun entity in this context, it requires the singular verb 'was'.
3
Combine the resolved verb forms.
The correct pair of verbs is 'were / was'.
This combination satisfies both the principle of proximity concord and fraction-noun concord.

Question 262Question →

Complete the sentence below by filling in the blank with the most appropriate modal verb phrase to express a past unfulfilled obligation.

Fill in the blanks below

The diplomatic envoys submitted their security credentials prior to entering the summit, but they completely ignored the directive.
Show answer & explanation

Answer

should have / ought to have
The sentence requires expressing a past obligation that was not carried out. The modal constructions 'should have' and 'ought to have', when paired with the past participle 'submitted', express that an action was expected in the past but was neglected.

Step-by-Step Solution

1
Identify the contextual meaning and time frame of the sentence.
The clause 'but they completely ignored the directive' indicates that the requirement existed in the past but was not fulfilled.
The sentence context demands a modal expression of past unfulfilled obligation.
2
Select the correct grammatical structure for past unfulfilled obligation.
The structure required is 'should have' or 'ought to have' followed by the past participle 'submitted'.
Combining 'should' or 'ought to' with the perfect auxiliary 'have' correctly conveys that an expected past action was omitted.

Read the sentence below carefully. Which preposition correctly completes the formal statement by filling the blank space?

Fill in the blanks below

The governing council affirmed that the financial compensation offered to department heads must be strictly commensurate their level of administrative responsibility and academic output.
Show answer & explanation

Answer

with
In standard formal English, the adjective 'commensurate' takes the dependent preposition 'with' when describing proportional balance or correspondence between two elements.

Step-by-Step Solution

1
Identify the key predicate adjective in the stem that requires a fixed prepositional complement.
The adjective 'commensurate' is the head word requiring a specific dependent preposition.
Certain adjectives in formal English mandate precise dependent prepositions to complete their semantic meaning.
2
Select the correct dependent preposition for 'commensurate'.
The preposition 'with' completes the prepositional phrase.
The adjective 'commensurate' standardly collocates with 'with' (e.g., 'commensurate with') to mean corresponding in size, extent, or degree.

Question 264Question →

Complete the sentence below by filling in the blank with the grammatically correct form of the verb.

Fill in the blanks below

Neither the chief researcher nor the laboratory technicians available when the inspection team arrived.
Show answer & explanation

Answer

The correct verb to fill the blank is 'were'.
When compound subjects are connected by 'neither... nor...', the verb agrees in number with the subject noun phrase nearest to it. Here, the plural noun 'technicians' is adjacent to the verb slot, and the past tense indicator 'arrived' establishes that the past plural verb 'were' is required.

Step-by-Step Solution

1
Analyze the subject structure of the sentence.
The sentence uses the correlative conjunction pair 'neither... nor...' joining two subjects: 'the chief researcher' (singular) and 'the laboratory technicians' (plural).
Correlative conjunctions require applying the rule of proximity concord.
2
Apply the rule of proximity concord.
The verb must agree in number with the subject noun phrase closest to the blank, which is the plural noun 'the laboratory technicians'.
Under proximity concord with 'neither... nor...', the nearest subject determines whether the verb is singular or plural.
3
Determine the correct tense and number for the verb.
Because the clause 'when the inspection team arrived' sets a past tense context, the required verb form is the past tense plural 'were'.
A plural subject combined with past tense context mandates the auxiliary verb 'were'.

Question 265Question →

Complete the sentence below with the correct modal expression:

'All guest lecturers _____ register at the main desk upon arrival, as it is a mandatory administrative requirement.'

Which of the following options correctly completes the sentence?

Show answer & explanation

Answer: must

Answer

The modal verb 'must' correctly expresses obligation and requirement without an added 'to' particle.
The verb 'must' accurately conveys compulsory obligation and correctly takes the bare infinitive verb form 'register'.

Step-by-Step Solution

1
Analyze the context of the sentence to identify the required modality.
The phrase 'mandatory administrative requirement' indicates official obligation.
Modal verbs express attitudes such as necessity, obligation, permission, or capability.
2
Select the appropriate modal auxiliary for obligation and verify its grammatical form.
'Must' is used for obligation and is followed by the bare infinitive 'register'.
Pure modal auxiliaries (can, could, may, might, must, shall, should, will, would) take a base verb without 'to'.

Question 266Question →

Complete the sentence below by providing the grammatically correct verb form for the blank space.

Fill in the blanks below

The Senate President insisted that the minister before the special committee to clarify the discrepancies in the fiscal budget.
Show answer & explanation

Answer

appear
The main verb 'insisted' introduces a mandative subjunctive clause ('that the minister...'). In English grammar, verbs of demand, request, or insistence take the base (uninflected) form of the verb in the subordinate clause, regardless of the main clause tense or subject number. Therefore, the bare infinitive 'appear' is the only grammatically correct choice.

Step-by-Step Solution

1
Identify the main governing verb and clause structure in the sentence.
The main verb 'insisted' governs a subordinate noun clause introduced by 'that' ('that the minister...').
Verbs expressing demand, insistence, recommendation, or request trigger the mandative subjunctive mood in subordinate clauses.
2
Determine the required verb form for mandative subjunctive constructions.
The mandative subjunctive requires the base (uninflected bare infinitive) form of the verb.
In subjunctive clauses following verbs of insistence, temporal inflections and third-person subject agreement markers are dropped, regardless of the main verb's past tense.
3
Select the base form of the verb to fill the blank.
The correct verb form is 'appear'.
'Appear' is the base form of the verb, satisfying the syntactic demands of the mandative subjunctive structure.

Question 267Question →

After analyzing the maritime logbook, the lead investigator concluded that the distressed vessel __________ its emergency beacon much earlier, given that severe gale warnings had already been broadcast.

Which of the following modal verb phrases correctly completes the sentence to express an unfulfilled past obligation?

Show answer & explanation

Answer: ought to have activated

Answer

The correct option is 'ought to have activated' because it properly forms the past modal structure expressing an unfulfilled past obligation.
The phrase 'ought to have activated' correctly combines the semi-modal 'ought to' with the perfect infinitive 'have activated' to express an action that was advisable or obligatory in the past but was omitted.

Step-by-Step Solution

1
Identify the required modality meaning from context
The context requires expressing a past action that was desirable or obligatory but did not happen ('unfulfilled past obligation').
The sentence indicates that gale warnings were sent prior, meaning activation was expected earlier than actually done.
2
Evaluate the grammatical structure of past modal auxiliaries
Past modal structures require 'modal + (to) + have + past participle'.
The bare infinitive 'have' must follow modal verbs like 'should' or 'ought to'.
3
Select the option that conforms to standard English modal grammar rules
'Ought to have activated' fits both the semantic requirement and structural rules.
It avoids double modals, incorrect infinitive particles, and incorrect auxiliary inflections.

Fill in the blanks below

Between the two architectural proposals submitted for the administrative complex, the committee considered the former far to the latter, noting that its layout had been planned than any other design evaluated this year.
Show answer & explanation

Answer

The first blank requires 'superior' (a Latin comparative adjective that takes the preposition 'to' rather than 'than' and cannot be modified by 'more'). The second blank requires 'more meticulously' (the comparative adverb form needed to modify the participle 'planned' when making a comparison).
The adjective 'superior' inherently carries a comparative sense derived from Latin, making 'more superior' redundant. It correctly pairs with the preposition 'to'. The phrase 'more meticulously' is the required comparative adverb modifying the verb participle 'planned'.

Step-by-Step Solution

1
Determine the correct adjective form for the first blank.
The word must modify the option and collocate with 'to the latter'. The adjective 'superior' is an inherent Latin comparative and must not be paired with 'more'.
Latin comparatives like 'superior', 'inferior', and 'prior' already express comparison and take 'to' instead of 'than'; adding 'more' creates an ungrammatical double comparative.
2
Determine the correct adverbial form for the second blank.
The word modifies the verb participle 'planned' in a comparative construction ('than any other design'), requiring the comparative adverb 'more meticulously'.
Adverbs ending in '-ly' form their comparative degree by adding 'more', and an adverb (not an adjective) must be used to modify a verb.

Question 269Question →

If the university management __________ the security warnings beforehand, the student protest would not have escalated into violence. Which of the following options correctly completes the sentence?

Show answer & explanation

Answer: had heeded

Answer

had heeded
The correct option uses the past perfect tense form 'had heeded' because the sentence represents a third conditional construction (an unreal condition in the past). In standard English grammar, when the main clause contains 'would have' + past participle ('would not have escalated'), the subordinate 'if'-clause must take the past perfect tense ('had' + past participle).

Step-by-Step Solution

1
Analyze the main clause structure of the sentence.
The main clause uses 'would not have escalated', which indicates a third conditional construction expressing a past unfulfilled event.
Identifying the structure of the result clause determines the required tense form for the conditional clause.
2
Apply the rule for third conditional 'if'-clauses.
A third conditional 'if'-clause requires the past perfect tense (had + past participle).
The past perfect tense is mandatory to express a hypothetical condition in the past.
3
Select the verb phrase that correctly matches the past perfect pattern.
The phrase 'had heeded' consists of 'had' followed by the past participle 'heeded'.
This completes the grammatically correct sequence of tenses for a third conditional sentence.

Question 270Question →

Which of the following options correctly completes the sentence below?

The community development project will proceed according to schedule, ______ the funding is released by the ministry before Friday.

Show answer & explanation

Answer: provided that

Answer

The correct option is 'provided that' because it introduces a subordinate clause of condition introduced by a finite clause.
'Provided that' is a complex subordinating conjunction used to introduce an adverbial clause of condition. Because the element following the blank is a complete finite clause ('the funding is released...'), a subordinating conjunction is required to join it to the main clause, establishing that the release of funds is the condition for proceeding.

Step-by-Step Solution

1
Analyze the structure following the blank
The segment 'the funding is released by the ministry before Friday' contains a complete subject ('the funding') and predicate ('is released...'), making it a finite subordinate clause.
Determines whether a conjunction or a preposition is required.
2
Distinguish between prepositions and conjunctions
Prepositions like 'despite' and 'in spite of' cannot introduce finite clauses directly without a relative structure like 'the fact that'. Subordinating conjunctions like 'provided that' and 'unless' can introduce full clauses.
Eliminates grammatically invalid prepositional choices.
3
Evaluate the logical context of the sentence
The main clause states the project will proceed under the positive condition that funds are released. 'Provided that' correctly expresses this prerequisite, whereas 'unless' ('if not') produces an illogical meaning.
Selects the conjunction that maintains both correct grammar and coherent logic.

Question 271Question →

Complete the sentence below by entering the correct plural form of the compound noun in the blank provided.

Fill in the blanks below

During the judicial review, the defense counsel submitted that the two convened by the military commander had proceeded without statutory jurisdiction.
Show answer & explanation

Answer

The correct form to fill the blank is 'courts-martial' (or 'courts martial').
In formal English, compound nouns composed of a noun followed by an adjectival modifier (such as court-martial, attorney-general, or passer-by) form their plurals by inflecting the principal noun. Since 'court' is the head noun modified by the adjective 'martial', the plural marker attaches to 'court', yielding 'courts-martial'.

Step-by-Step Solution

1
Identify the headword of the compound noun structure.
In the compound noun 'court-martial', 'court' is the principal noun (headword) and 'martial' is a post-positive adjective acting as a modifier.
Plural inflection in English compound nouns attaches to the principal noun head, not to post-modifying adjectives.
2
Apply the pluralization rule to the head noun.
Pluralizing 'court' yields 'courts', resulting in 'courts-martial'.
The quantifier 'two' requires a plural noun phrase.

Question 272Question →

Complete the following sentence by providing the grammatically appropriate verb tense and aspect form for the blank.

Fill in the blanks below

The lead investigator remarked that had the forensic team the crime scene immediately after the incident, crucial digital evidence would not have been corrupted.
Show answer & explanation

Answer

The correct verb form to fill the blank is 'secured' (or 'cordoned off'), which provides the past participle needed for an inverted third conditional structure.
The sentence contains an inverted third conditional clause ('had the forensic team...'), which expresses an unfulfilled hypothetical condition in the past. An inverted third conditional replaces 'if the forensic team had secured' with 'had the forensic team secured'. The auxiliary 'had' strictly requires the past participle form of the main verb ('secured') to combine with the main clause's perfect conditional form 'would not have been corrupted'.

Step-by-Step Solution

1
Analyze the syntactic structure of the conditional clause.
The clause 'had the forensic team {{blank_1}}' represents an inverted third conditional structure where 'if' is omitted and the auxiliary verb 'had' is inverted with the subject 'the forensic team'.
In formal English, third conditional protases frequently omit 'if' by placing the auxiliary 'had' before the subject.
2
Identify the required principal part of the verb following the auxiliary 'had'.
The perfect auxiliary 'had' demands a past participle verb form ('secured').
The apodosis (main clause) contains 'would not have been corrupted' (modal + have + past participle), requiring the past perfect aspect (had + past participle) in the conditional clause to complete the third conditional counterfactual pattern.

Question 273Question →

Read the sentence below: "One of the principal objectives of the new environmental policies _____ to reduce carbon emissions across all industrial sectors." Which of the options correctly completes the sentence?

Show answer & explanation

Answer: is

Answer

The singular verb 'is' correctly completes the sentence.
The correct verb choice is 'is' because the grammatical subject of the sentence is the singular pronoun 'One'. Intervening plural phrases such as 'of the new environmental policies' do not alter the singular nature of the subject.

Step-by-Step Solution

1
Identify the complete subject phrase in the sentence.
The subject phrase is 'One of the principal objectives of the new environmental policies'.
The main verb must agree syntactically with the head of this subject phrase.
2
Determine the syntactic head noun/pronoun of the subject.
The head of the phrase is 'One' (singular). The post-modifying prepositional phrases ('of the principal objectives', 'of the new environmental policies') do not change the number of the subject head.
Nouns inside intervening prepositional phrases do not govern the verb.
3
Match the singular subject head to the appropriate singular verb.
The singular present tense verb 'is' completes the sentence correctly.
Singular subjects require singular verbs in English concord.

Complete the sentence with the most appropriate verb form: 'It is high time the ministry _____ the newly constructed bridge to the public.' Which option correctly completes the sentence?

Show answer & explanation

Answer: opened

Answer

opened
The expression 'It is high time' followed by a subject noun phrase ('the ministry') requires a simple past tense verb ('opened') to indicate that an action ought to have been taken already.

Step-by-Step Solution

1
Identify the key grammatical expression in the stem.
The sentence begins with the idiomatic expression 'It is high time' followed by a noun phrase subject ('the ministry').
Expressions like 'It is time' or 'It is high time' follow specific subjunctive verb rules when followed by a subject.
2
Apply the rule for unreal past / subjunctive mood.
The main verb following 'It is high time + subject' must be in the simple past tense ('opened').
Although the time reference is present or future, the simple past tense form is used to express that an action is already overdue.

Complete the sentence below by providing the grammatically correct possessive pronoun in each blank to ensure proper pronoun-antecedent agreement.

Fill in the blanks below

Although the committee was unanimous in evaluation of the proposal, the jury were divided in opinions regarding the defendant's guilt.
Show answer & explanation

Answer

The first blank requires the singular possessive pronoun 'its' to agree with the collective noun 'committee' acting as a unified entity. The second blank requires the plural possessive pronoun 'their' to agree with the collective noun 'jury' acting as separate individuals.
In formal English grammar, collective nouns require singular pronouns when the group acts as a single, unified body, and plural pronouns when the individuals within the group act separately. In the first clause, the singular verb 'was' and 'unanimous' establish that the 'committee' acted as one unit, necessitating the singular possessive pronoun 'its'. In the second clause, the plural verb 'were' and the word 'divided' show that the members of the 'jury' acted as separate individuals, necessitating the plural possessive pronoun 'their'.

Step-by-Step Solution

1
Analyze the antecedent and context for the first blank.
The antecedent is 'committee'. The singular verb 'was' and the adjective 'unanimous' indicate that the committee is acting as a single, collective unit.
When a collective noun operates as a single entity, it takes a singular pronoun ('its').
2
Analyze the antecedent and context for the second blank.
The antecedent is 'jury'. The plural verb 'were' and the adjective 'divided' demonstrate that the members of the jury are acting individually with differing views.
When members of a collective noun act individually or are in disagreement, the collective noun takes a plural pronoun ('their').

Question 277Question →

Consider the following sentence:

'The university senate awarded the most outstanding graduating student a prestigious research grant during the annual convocation.'

What syntactic function does the bolded noun phrase perform in this sentence?

Show answer & explanation

Answer: Indirect object of the verb

Answer

The bolded noun phrase functions as the indirect object of the verb.
In ditransitive clause patterns following verbs of transfer like 'awarded', the noun phrase that receives the item comes immediately after the verb and functions as the indirect object. Because 'the most outstanding graduating student' names the recipient of the grant, it is the indirect object.

Step-by-Step Solution

1
Analyze the main predicate structure of the sentence
The verb 'awarded' functions as a ditransitive verb requiring two object arguments: a receiver and a item.
In standard English clause syntax [Subject + Verb + Indirect Object + Direct Object], ditransitive verbs take two complement noun phrases.
2
Identify the semantic role and syntactic position of the bolded noun phrase
The noun phrase 'the most outstanding graduating student' precedes the direct object ('a prestigious research grant') and denotes the recipient.
The entity receiving the entity transferred by the verb is syntactically defined as the indirect object.

Question 278Question →

The defense counsel argued that forcing the witness to testify without legal representation was tantamount _____ a violation of his fundamental human rights. Which preposition correctly completes the sentence?

Show answer & explanation

Answer: to

Answer

The preposition 'to' is the correct choice because 'tantamount' forms a fixed dependent prepositional combination 'tantamount to', meaning equivalent in value, significance, or effect.
The preposition 'to' forms the proper grammatical collocation with 'tantamount'. In English, 'tantamount to' is a fixed construction meaning equivalent in effect or seriousness.

Step-by-Step Solution

1
Identify the key adjective requiring a dependent preposition in the sentence.
The target word is the predicate adjective 'tantamount'.
Understanding the head word determines which preposition must follow it in standard English grammar.
2
Recall the established dependent preposition and collocation rule for 'tantamount'.
The adjective 'tantamount' takes the preposition 'to' (tantamount to something).
Prepositional complements following specific adjectives are fixed and governed by convention, not interchangeable with near-synonyms.

Question 279Question →

Which of the following verb forms correctly completes the sentence?

'Professor Adeleke is one of the few scholars who _______ consistently published groundbreaking research in indigenous linguistics.'

Show answer & explanation

Answer: have

Answer

The correct option is 'have'. In relative clause constructions following expressions such as 'one of the [plural noun] who...', the relative pronoun 'who' refers to the plural antecedent noun ('scholars'), which requires a plural verb ('have').
The verb form 'have' is correct. In constructions with the structure 'one of the [plural noun] who/that', the relative pronoun takes the plural number of the preceding noun ('scholars'). Therefore, the plural auxiliary verb 'have' must be used.

Step-by-Step Solution

1
Identify the antecedent noun modified by the relative pronoun 'who'.
The relative pronoun 'who' modifies the plural noun antecedent 'scholars', not the pronoun 'one' or the subject 'Professor Adeleke'.
Relative pronouns inherit the number and person of their immediate antecedent noun.
2
Select the verb form that agrees in number with the plural antecedent noun.
The plural verb 'have' correctly completes the relative clause 'who have consistently published...'.
A plural noun antecedent requires a plural verb form to maintain proper grammatical concord.

Question 280Question →

The retiring vice-chancellor spoke of the university's modest beginnings as though he _______ present during its founding fifty years ago, whereas he only joined the institution last decade.

Which of the following verb forms correctly completes the sentence?

Show answer & explanation

Answer: had been

Answer

The past perfect subjunctive form 'had been' correctly completes the sentence.
The conjunction 'as though' requires a subjunctive verb form to indicate a counterfactual or unreal condition. Because the founding occurred in the distant past (fifty years ago relative to the past action of speaking), the past perfect subjunctive 'had been' is required to mark past unfulfilled aspect.

Step-by-Step Solution

1
Analyze the matrix clause tense and the subordinate clause function.
The main verb 'spoke' sets a past tense time frame, while 'as though' introduces a hypothetical (unreal) situation.
Expressions like 'as if' and 'as though' require subjunctive mood verb forms to indicate counterfactual conditions.
2
Determine the time reference of the hypothetical situation relative to the main verb.
The founding occurred fifty years ago (prior to the time of speaking), making it an unreal condition in the past.
An unreal condition referring to past time requires the past perfect subjunctive ('had + past participle').
3
Evaluate the choices based on tense and aspect rules.
The verb form 'had been' properly reflects the past perfect aspect demanded by an unfulfilled past hypothesis.
The simple past subjunctive ('were') is reserved for present unreal scenarios, whereas 'had been' shifts back to account for prior past time.
