Question 1Question

During the public hearing, the tribunal chairman insisted that the key witness _______ the assembly before the final ruling was delivered. Which of the following verb forms correctly completes the sentence?

Show answer & explanation

Answer: address

Answer

address
The correct form is the bare base verb 'address'. When a sentence contains a verb of demand, command, or insistence like 'insisted that', the embedded clause requires the mandative subjunctive, which uses the base form of the verb irrespective of the subject or the tense of the principal clause.

Step-by-Step Solution

1
Identify the reporting verb and clause structure in the stem.
The main clause uses the verb of command/demand 'insisted that'.
Verbs expressing recommendation, demand, requirement, or insistence trigger the mandative subjunctive mood in subordinate 'that' clauses.
2
Determine the required verb form for the mandative subjunctive mood.
The bare infinitive / base form of the verb ('address') must be used.
The mandative subjunctive does not inflect for tense, aspect, or person (e.g., no '-s' ending for singular subjects and no past tense markers).

Question 2Question

Which verb form correctly completes the sentence below in accordance with the rules of subject-verb concord?

"Neither the project manager nor the field supervisors _______ informed about the sudden change in schedule."

Show answer & explanation

Answer: were

Answer

The correct option is 'were'.
In English grammar, when two subjects are connected by correlative conjunctions such as 'neither... nor' or 'either... or', the verb agrees in number with the subject that is nearest to it in the sentence. Here, 'field supervisors' is a plural noun phrase adjacent to the verb blank, so it requires the plural past tense verb 'were'.

Step-by-Step Solution

1
Identify the conjunction structure and subject components in the sentence.
The sentence uses the correlative conjunction pair 'neither... nor' connecting two subjects: 'the project manager' (singular) and 'the field supervisors' (plural).
Correlative conjunctions like 'either... or' and 'neither... nor' follow specific proximity agreement rules.
2
Apply the rule of proximity concord for correlative conjunctions.
The verb must agree in person and number with the subject noun phrase closest to the blank, which is 'the field supervisors' (plural).
In 'neither A nor B' constructions, the subject closer to the verb determines whether the verb is singular or plural.
3
Select the correct plural past tense verb form.
The plural past tense verb form required is 'were'.
'Were' correctly satisfies plural agreement with 'field supervisors'.

Question 3Question

The managing director made it explicitly clear during yesterday's meeting that he would rather the regional supervisor _______ the comprehensive audit report himself before submitting it to the executive board. Which of the following option forms correctly completes the sentence?

Show answer & explanation

Answer: drafted

Answer

The past tense form 'drafted' correctly completes the sentence under the rules of subjunctive unreal past structures.
The verb form 'drafted' is correct because English syntax mandates the simple past tense (unreal past) when 'would rather' is followed by a different subject clause ('would rather someone did something').

Step-by-Step Solution

1
Identify the controlling grammatical structure in the sentence.
The structure is 'would rather' followed by a explicit noun phrase subject ('the regional supervisor').
When 'would rather' takes a clause with its own subject, it introduces a past subjunctive clause.
2
Determine the correct verb inflection required by 'would rather + subject'.
The verb must be in the simple past form ('drafted') to signal hypothetical preference/unreal past.
In formal English grammar, preference expressed for another agent's action demands the past tense form regardless of present or future context.
3
Evaluate the option choices against this rule.
Only 'drafted' satisfies the unreal past subjunctive requirement.
Forms like 'drafts', 'should draft', and 'has drafted' fail to observe the subjunctive tense shift rule.

Question 4Question

Choose the option that correctly completes the sentence below.

Each of the candidates _____ given a copy of the examination syllabus before the test began.

Which option correctly completes the sentence?

Show answer & explanation

Answer: was

Answer

The correct option is 'was'.
The verb must agree with the singular head pronoun 'Each'. The intervening plural noun 'candidates' within the prepositional phrase does not change the grammatical number of the subject. Therefore, the singular past verb 'was' is grammatically correct.

Step-by-Step Solution

1
Identify the grammatical subject of the sentence.
The head word of the subject phrase is the indefinite pronoun 'Each', which is grammatically singular.
Prepositional modifiers like 'of the candidates' do not alter the number of the head pronoun.
2
Select the singular verb form matching the past tense context.
The singular past tense verb 'was' agrees with the subject 'Each'.
Singular subjects require singular verbs according to standard rules of subject-verb concord.

Question 5Question

Which option correctly completes the sentence below?

Hardly had the manager stepped into the office _____ the telephone rang.

Show answer & explanation

Answer: when

Answer

The conjunction 'when' correctly completes the sentence.
The sentence uses the inverted restrictive structure starting with 'Hardly', which obligatorily pairs with the subordinator 'when' to express two immediate consecutive events.

Step-by-Step Solution

1
Identify the introductory restrictive adverbial structure.
The sentence begins with 'Hardly had...', which uses an inverted auxiliary-subject structure.
Sentences introduced by restrictive adverbs such as 'hardly', 'scarcely', or 'barely' require inverted word order in the main clause.
2
Determine the correct correlative subordinator.
The adverb 'hardly' pairs specifically with 'when' to connect the main clause to the time clause.
Standard grammatical convention dictates that 'hardly... when' expresses two events occurring in immediate sequence.

Question 6Question

Which option best completes the sentence to express an unreal or hypothetical situation correctly: 'The executive director presided over the meeting as though he ______ the entire conglomerate himself, despite owning no shares'?

Show answer & explanation

Answer: owned

Answer

The simple past verb form 'owned' correctly completes the sentence by establishing the unreal past subjunctive mood required after the conjunction 'as though'.
The simple past tense verb form 'owned' is correct because the conjunction 'as though' requires an unreal past construction (subjunctive mood) to indicate that the situation is hypothetical or contrary to fact.

Step-by-Step Solution

1
Identify the clause structure and conjunction introduced in the stem.
The sentence uses the subordinating conjunction 'as though' following a main clause in the past tense.
Expressions such as 'as if' and 'as though' signal that the following clause describes a hypothetical or contrary-to-fact scenario.
2
Determine the correct mood and tense required for unreal/hypothetical comparisons.
The subjunctive mood expressed via the simple past tense 'owned' is necessary.
English grammar uses past tense verb forms to express hypothetical distance from reality in present or past reference frames.

Question 7Question

Which of the following verb forms best completes the sentence? 'It is high time the local authority ________ the broken bridge.'

Show answer & explanation

Answer: repaired

Answer

repaired
The phrase 'it is high time' is followed by a clause containing a subject and a verb in the simple past tense ('repaired'). This subjunctive structure is used to indicate that an action should already have been taken.

Step-by-Step Solution

1
Identify the key fixed expression in the sentence clause.
The clause begins with 'It is high time'.
The expression 'it is high time' introduces an unreal past/subjunctive construction expressing urgency for an action that ought to be done now.
2
Apply the appropriate verb tense rule for unreal past expressions.
The verb following the subject in this structure must be in the simple past tense.
English grammar rules mandate that 'it is high time + subject' takes a simple past verb form to denote present/future obligation.
3
Select the correct past simple verb form.
'repaired' is the past simple form of 'repair'.
This correctly fulfills the subjunctive requirement of the sentence.

Question 8Question

By the time the judicial commission submits its findings next month, the principal investigator __________ key witnesses for over six weeks.

Which of the following verb forms best completes the sentence?

Show answer & explanation

Answer: will have been questioning

Answer

will have been questioning
The correct verb form is 'will have been questioning'. When describing an action that continues over a duration leading up to a specific future reference point (introduced by 'by the time... next month'), English grammar requires the future perfect continuous aspect to express both ongoing duration and relative future completion.

Step-by-Step Solution

1
Analyze the time markers and temporal framework in the sentence.
The clause 'By the time the judicial commission submits its findings next month' establishes a specific future point of reference, while 'for over six weeks' indicates an ongoing duration.
Identifying the temporal anchor and aspectual requirements is necessary to select the correct complex tense.
2
Determine the precise tense and aspect combination needed.
The future perfect continuous aspect ('will have been' + present participle) is required to show an action continuing up to a designated future time.
Simple future and present tenses cannot represent an action's duration completed relative to a future milestone.

Question 9Question

Fill in the blank with the correct possessive pronoun that agrees with its antecedent in the sentence below.

Fill in the blanks below

The city council decided to revise municipal budget during the executive session.
Show answer & explanation

Answer

The correct pronoun is 'its'.
The singular possessive pronoun 'its' correctly agrees with the collective noun antecedent 'city council', which functions as a single unified unit in this context.

Step-by-Step Solution

1
Identify the antecedent in the sentence.
The antecedent is the noun phrase 'The city council'.
The missing word is a possessive pronoun referring back to the body making the decision.
2
Determine the grammatical number and person of the antecedent.
'City council' is a singular collective noun functioning as a single acting entity.
When a collective noun acts as a single unified body, it takes a singular neuter pronoun.
3
Select the possessive pronoun that matches the antecedent in number and gender.
The third-person singular neuter possessive pronoun is 'its'.
Proper pronoun-antecedent agreement requires a singular pronoun ('its') to agree with the singular collective antecedent ('city council').

Question 10Question

Which word correctly fills the blank to ensure proper subject-verb concord in the sentence below?

Fill in the blanks below

Dr. Adebayo is one of the prominent researchers who actively advocating for renewable energy adoption in West Africa.
Show answer & explanation

Answer

are
In sentences structured around the phrase 'one of the... who', the relative pronoun 'who' refers to the plural noun immediately preceding it ('researchers'). Consequently, the verb within the relative clause must be plural ('are').

Step-by-Step Solution

1
Identify the relative pronoun and its antecedent in the clause.
The relative pronoun is 'who', and its antecedent is the plural noun 'researchers'.
In the construction 'one of the [plural noun] who...', the relative pronoun 'who' refers back to the plural noun preceding it, not to 'one'.
2
Determine the required number (singular or plural) for the verb in the relative clause.
A plural verb form is required to match the plural antecedent 'researchers'.
A relative pronoun takes a verb that agrees in number with its antecedent.
3
Select the correct present continuous auxiliary verb form.
The plural auxiliary verb 'are' correctly completes 'are actively advocating'.
'Are' agrees in number with 'researchers' and maintains proper present continuous tense with 'advocating'.

Question 11Question

Reviewing the tactical operation, the lead investigator noted that the convoy commanders _______ through the demilitarized zone without clearance, given that standing orders explicitly forbade any nocturnal movement. Which of the following modal verb phrases correctly completes the sentence to express a past breach of obligation or advisability while adhering to standard grammatical rules?

Show answer & explanation

Answer: should not have proceeded

Answer

The phrase 'should not have proceeded' correctly completes the sentence by expressing a past action that took place despite being inadvisable or against obligation, while following proper modal verb syntax.
The verb phrase 'should not have proceeded' is grammatically sound and expresses past inadvisability or breach of obligation. The modal verb 'should' takes a bare infinitive ('have proceeded') to form the perfect aspect, indicating that an action took place in the past when it ought not to have.

Step-by-Step Solution

1
Analyze the semantic context of the sentence.
The sentence describes an action taken in the past (moving through the zone) that violated standing orders, requiring a modal structure for past unfulfilled obligation or advisability.
Modal auxiliaries express different nuances of modality such as necessity, permission, obligation, or logical deduction depending on context and tense structure.
2
Evaluate the syntactic rules governing modal and semi-modal auxiliaries.
Pure modal verbs ('should', 'must', 'might') must be followed by a bare infinitive (e.g., 'have proceeded'), whereas 'ought' requires the full infinitive marker 'to'. Double modals (e.g., 'might could') are grammatically invalid in standard English.
Modal verb complementation rules strictly dictate whether a bare infinitive, a 'to'-infinitive, or a perfective auxiliary follows.
3
Select the option that satisfies both semantic intent and structural accuracy.
'should not have proceeded' correctly uses 'should not' + perfective infinitive ('have proceeded') without ungrammatical particles or double modal constructions.
This form accurately conveys that the action occurred in the past despite prohibition/inadvisability.

Question 12Question

Consider the sentence below:

'The university governing council declared the newly appointed Vice-Chancellor's ten-year strategic development plan a masterclass in sustainable administration during the press briefing.'

What is the exact syntactic function of the bolded noun phrase *'a masterclass in sustainable administration'* in this sentence?

Show answer & explanation

Answer: Object complement

Answer

The bolded noun phrase functions as an object complement.
The phrase 'a masterclass in sustainable administration' functions as an object complement because it follows the direct object ('the newly appointed Vice-Chancellor's ten-year strategic development plan') and completes the predicate after the complex transitive verb 'declared'.

Step-by-Step Solution

1
Identify the verb and its clause structure
The main verb is 'declared', which is a complex transitive verb requiring both a direct object and an object complement.
Complex transitive verbs (such as declare, consider, make, call) take a direct object followed by an element that describes or renames that object.
2
Identify the direct object of the verb
The noun phrase 'the newly appointed Vice-Chancellor's ten-year strategic development plan' receives the direct action of 'declared'.
This noun phrase is the entity being declared.
3
Analyze the role of the bolded noun phrase following the direct object
The noun phrase 'a masterclass in sustainable administration' completes the meaning of the direct object by expressing an essential property attributed to it.
A noun phrase that predicates a quality or identity of the direct object is an object complement.

Question 13Question

Read the sentence below and answer the question that follows.

The university governing council unanimously declared Dr. Evelyn Olayemi [the principal architect of the new academic curriculum].

What is the syntactic function of the bracketed noun phrase in the sentence above?

Show answer & explanation

Answer: Object complement

Answer

Object complement
The correct answer is 'Object complement' because the noun phrase 'the principal architect of the new academic curriculum' follows the direct object ('Dr. Evelyn Olayemi') and completes the predicate of the complex-transitive verb 'declared' by supplying the official role assigned to that object.

Step-by-Step Solution

1
Analyze the clause structure and identify the main verb.
The main verb is 'declared', which is a complex-transitive verb requiring both a direct object and an object complement.
Complex-transitive verbs cannot stand with only a direct object without leaving the clause predicate incomplete.
2
Identify the noun phrase receiving the direct action of the verb.
'Dr. Evelyn Olayemi' is the direct object of the verb 'declared'.
She is the person being designated by the governing council.
3
Determine the grammatical relationship between the direct object and the bracketed noun phrase.
The bracketed phrase 'the principal architect of the new academic curriculum' defines and completes the role attributed to the direct object.
A noun phrase that renames or characterizes a direct object following verbs of declaring, appointing, or electing functions as an object complement.

Question 14Question

Complete the sentence with the most appropriate verb form: 'It is high time we ________ home to prepare for the upcoming examination.' Which option correctly completes the sentence?

Show answer & explanation

Answer: went

Answer

went
The expression 'it is high time' when followed immediately by a subject pronoun ('we') requires the verb to be in the simple past tense form to indicate unreal past or subjunctive mood.

Step-by-Step Solution

1
Identify the key grammatical expression in the sentence structure.
The phrase 'It is high time' introduces a clause expressing an urgent action that should already have taken place.
Identifying fixed structures determines the appropriate grammatical mood and verb tense required.
2
Apply the unreal past (subjunctive) rule for 'it is high time' followed by a personal subject pronoun.
When 'it is high time' is followed by a noun or subject pronoun ('we'), the finite verb must be in the simple past tense ('went').
In standard English grammar, expressions such as 'it is time' or 'it is high time' mandate the use of simple past tense to convey present or future necessity with a sense of delay.

Question 15Question

Given that the lead researcher was stranded at the airport without internet access throughout the evening, she __________ the confidential report yesterday as claimed. Which of the following modal expressions correctly completes the sentence to express logical impossibility regarding a past event?

Show answer & explanation

Answer: could not have submitted

Answer

The expression 'could not have submitted' is the correct modal construction to express logical impossibility regarding a past action.
The modal phrase 'could not have submitted' correctly pairs the negative modal auxiliary 'could not' with the perfective helper 'have' and the past participle 'submitted'. This structure standardly conveys a logical deduction that a past event was impossible.

Step-by-Step Solution

1
Analyze the temporal context and the speaker's intent.
The context describes a completed past situation ('yesterday', 'was stranded') where an action was factually impossible.
Modal auxiliaries expressing past logical deduction or negative certainty require past modal structures (modal + have + past participle).
2
Determine the appropriate modal auxiliary for past logical impossibility.
'Could not have' + past participle is used to deduce that a past action was impossible given the circumstances.
Expressing that something definitely did not happen due to surrounding evidence requires negative past epistemic modality.
3
Evaluate the choices for grammatical validity.
'Could not have submitted' is syntactically sound, while other options contain double modals, tense mismatch, or improper verb inflections.
English syntax forbids double central modals ('might can') and requires correct aspectual forms after modal markers.

Question 16Question

Considering that the doors were locked from the inside and all security alarms were active until morning, the nocturnal intruder ________ inside the building before the staff departed for the evening. Which option correctly completes the sentence to express a strong past logical deduction?

Show answer & explanation

Answer: must have hidden

Answer

The correct option is 'must have hidden', which appropriately expresses a logical deduction about a past event using 'must + have + past participle'.
The phrase 'must have hidden' correctly conveys a past logical deduction drawn from clear surrounding evidence. In English grammar, past logical conclusions are constructed using 'must' followed by the perfect infinitive ('have' + past participle).

Step-by-Step Solution

1
Analyze the semantic context of the sentence
The sentence presents physical evidence (locked doors, active alarms) pointing to a logical conclusion about a past event.
Determining whether the context demands past obligation, permission, capability, or past logical deduction guides modal selection.
2
Identify the required modal auxiliary structure for past deduction
A past logical certainty requires the auxiliary pattern 'must + have + past participle'.
Pure modals cannot take past tense inflections directly and require the perfect auxiliary 'have' to refer to past time.
3
Evaluate the choices for grammatical correctness and modal syntax
'must have hidden' follows standard modal syntax, while double modals ('might can') and non-standard inflections ('must to', 'oughted to') are ungrammatical.
Modal auxiliaries in English do not take infinitive 'to' markers, cannot be stacked consecutively, and do not accept inflectional suffixes.

Question 17Question

Select the option that best completes the sentence:

Considering the tight deadline, the project team __________ submitted the proposal yesterday, but technical difficulties delayed their final upload.

Which of the following modal verb structures correctly completes the sentence?

Show answer & explanation

Answer: ought to have

Answer

The correct option is 'ought to have'.
The phrase 'ought to have' correctly expresses an action that was expected to happen in the past. The semi-modal verb 'ought' requires the preposition 'to', followed by the base auxiliary 'have' and the past participle 'submitted'.

Step-by-Step Solution

1
Analyze the sentence context and temporal frame
The clause mentions an action scheduled for the past ('yesterday') that was expected but hindered by technical difficulties.
Past unfulfilled expectations or obligations require a perfect modal verb structure (modal + have + past participle).
2
Evaluate candidate modal structures for grammatical correctness
'Ought to have' follows standard grammar rules for semi-modal past obligations. Options featuring double modals, redundant 'to' particles after pure modals, or past-tense auxiliary forms like 'had' violate core modal syntax rules.
Pure modals take bare infinitives and cannot be combined or followed directly by past tense forms.

Question 18Question

Despite strong objections from the minority shareholders, the board of directors eventually acquiesced _____ the proposal to merge with the multinational corporation. Which of the following prepositions correctly completes the sentence?

Show answer & explanation

Answer: in

Answer

The preposition 'in' correctly completes the sentence as the verb 'acquiesce' standardly governs 'in'.
The verb 'acquiesce' (meaning to accept or agree to something reluctantly without protest) strictly takes the dependent preposition 'in'. Therefore, the completed sentence correctly reads: '...eventually acquiesced in the proposal...'.

Step-by-Step Solution

1
Identify the head verb in the sentence requiring a dependent preposition.
The verb is 'acquiesced'.
Dependent prepositions are fixed by the governing verb that precedes the gap.
2
Determine the correct standard prepositional complement for 'acquiesce'.
The correct complement is 'in'.
In standard formal English grammar, one acquiesces 'in' a matter, arrangement, or decision.
3
Evaluate and eliminate distractors based on false analogies with similar verbs.
Options using 'to', 'with', and 'for' are rejected.
Expressions like 'agree to' or 'comply with' lead to L1 transfer or analogy errors, but 'acquiesce' exclusively requires 'in'.

Question 19Question

In the sentence, 'The university senate considered the newly appointed registrar, a seasoned academic administrator with decades of public service, a formidable candidate for the position,' what is the syntactic function of the noun phrase 'a formidable candidate for the position'?

Show answer & explanation

Answer: Object complement

Answer

Object complement
In complex transitive clause structures (verbs such as consider, appoint, elect, declare), the verb takes a direct object followed by an object complement. The noun phrase 'a formidable candidate for the position' defines the role attributed to the direct object 'the newly appointed registrar', making its syntactic function an object complement.

Step-by-Step Solution

1
Analyze the main verb and sentence predicate structure
The main verb 'considered' is a complex transitive verb, which requires both a direct object and an object complement to complete its meaning.
Identifying the transitive nature of the verb dictates the structural roles available for subsequent noun phrases.
2
Differentiate between appositives and required complements
'The newly appointed registrar' is the direct object, followed immediately by the parenthetical appositive 'a seasoned academic administrator with decades of public service'.
Separating non-essential explanatory noun phrases isolates the core clause elements.
3
Evaluate the relationship between the target phrase and the direct object
The noun phrase 'a formidable candidate for the position' defines the property or state ascribed to the direct object by the senate.
A noun phrase that completes the sentence by describing or renaming the direct object functions specifically as an object complement.

Question 20Question

Read the sentence below and fill in the blank with the correct word:

Every one of the delegates, together with the foreign observers, _____ satisfied with the resolutions reached at the summit.

Which of the following options correctly completes the sentence?

Show answer & explanation

Answer: was

Answer

was
The sentence requires the singular verb 'was' because the grammatical subject is the singular indefinite pronoun phrase 'Every one'. The clause 'together with the foreign observers' is a prepositional phrase that modifies the subject but does not change its singular number.

Step-by-Step Solution

1
Identify the main head subject of the clause.
The head subject is 'Every one', which is a singular indefinite pronoun structure.
Expressions like 'together with', 'along with', and 'as well as' introduce prepositional modifiers that do not alter the number of the subject.
2
Apply the rule of subject-verb concord for singular head subjects with intervening plural nouns.
The verb must be singular to agree with 'Every one', disregarding the plural noun 'observers' inside the modifier.
Failing to ignore the intervening plural noun leads to the error of proximity.
3
Select the singular past-tense verb that completes the sentence grammatically.
The singular verb 'was' correctly completes the clause.
'Was' provides proper singular concord and agrees with the past tense context of the sentence.
