Complete the passive sentence below by providing the exact passive verb phrase that correctly transforms the given active sentence while preserving its original tense and aspect.

Fill in the blanks below

Active: The regulatory committee is auditing the financial statements of the firm.
Passive: The financial statements of the firm by the regulatory committee.
Show answer & explanation

Answer

are being audited
The active sentence uses the present continuous tense ('is auditing'). When converting to passive voice, the object 'The financial statements of the firm' becomes the new subject. Since 'statements' is plural, it requires the plural auxiliary 'are', followed by 'being' to express continuous aspect, and the past participle 'audited'.

Step-by-Step Solution

1
Identify the tense and aspect of the active verb phrase.
The active verb phrase 'is auditing' is in the present continuous (progressive) tense.
Maintaining exact tense and aspect is mandatory in active-to-passive voice transformation.
2
Determine the subject of the passive sentence and check subject-verb agreement.
The new subject is 'The financial statements of the firm', which is plural ('statements').
The auxiliary verb must agree in number with the new passive subject, requiring 'are' instead of 'is'.
3
Form the present continuous passive verb structure.
Present continuous passive formula: auxiliary 'be' (are) + being + past participle (audited) = 'are being audited'.
The continuous aspect is retained using 'being' followed by the past participle of the main verb.

Question 162Question →

The accused person appeared completely indifferent _____ the feelings of the victim's family throughout the trial. Which preposition correctly completes the sentence?

Show answer & explanation

Answer: to

Answer

to
The correct answer is 'to' because the adjective 'indifferent' requires the dependent preposition 'to' to form a standard grammatical collocation meaning unconcerned or uninfluenced.

Step-by-Step Solution

1
Identify the key adjective governing the preposition in the sentence.
The target adjective is 'indifferent'.
Certain adjectives in English require specific dependent prepositions to complete their meaning.
2
Determine the correct dependent preposition associated with 'indifferent'.
The preposition 'to' correctly pairs with 'indifferent' ('indifferent to').
'Indifferent to' is the fixed idiom meaning unconcerned, uninfluenced, or lacking interest.

Question 163Question →

Complete the sentence below by providing the grammatically correct verb forms that satisfy standard subject-verb agreement rules.

Fill in the blanks below

Not only the presiding judge but also the jury members convinced of the suspect's guilt, especially since more than one witness testified under oath.
Show answer & explanation

Answer

The correct verb form for the first blank is 'were' and for the second blank is 'has'.
The first blank requires 'were' because the plural noun phrase 'the jury members' is closer to the verb position in a 'not only... but also' construction. The second blank requires 'has' because 'more than one' followed by a singular countable noun ('witness') requires a singular verb under standard grammatical concord.

Step-by-Step Solution

1
Determine the subject and proximity rule for the first blank.
In sentences linked by correlative conjunctions like 'not only... but also...', the verb must agree in number with the closer subject. The subject closer to the verb is 'the jury members' (plural), which requires the plural verb 'were'.
Proximity concord dictates that the nearer element in a correlative structure controls verb agreement.
2
Determine the concord rule governing the expression in the second blank.
The phrase 'more than one witness' contains the expression 'more than one' followed by a singular countable noun ('witness'). In standard formal English, this structure strictly requires a singular verb ('has').
Despite referring conceptually to multiple entities, the phrase 'more than one + singular noun' follows grammatical concord and takes a singular verb.

Key Concept

Proximity concord with correlative conjunctions and grammatical concord with 'more than one'
Question 164Question →

Complete the sentence below by supplying the correct auxiliary verb in the blank.

Fill in the blanks below

Scarcely the lead researcher submitted the final manuscript when the journal editor requested additional control experiments.
Show answer & explanation

Answer

had
The auxiliary verb 'had' correctly completes the past perfect aspect in an inverted sentence structure introduced by 'Scarcely'. This pattern ('Scarcely had + subject + past participle ... when + simple past') indicates an action completed just prior to another past event.

Step-by-Step Solution

1
Analyze the sentence structure initiating with the limiting negative adverb 'Scarcely'.
Identify that initial negative adverbials require subject-auxiliary inversion.
In formal English grammar, placing 'Scarcely' at the sentence start forces the auxiliary verb to precede the subject.
2
Determine the correct tense aspect required by the correlated temporal clause starting with 'when'.
Select the past perfect auxiliary 'had' to precede the past participle 'submitted'.
The paired construction 'Scarcely had... when...' expresses that one event in the past occurred immediately before another past event ('requested').

Question 165Question →

Complete the sentence below by supplying the grammatically correct modifier in the blank space provided.

Fill in the blanks below

Of the two structural audit reports submitted to the ministry, the committee considered the second one to be the comprehensive.
Show answer & explanation

Answer

more
The modifier 'more' is correct because standard English rules of modification dictate that the comparative degree ('more') must be used when comparing exactly two entities. The superlative degree ('most') is ungrammatical in this context as it requires a comparison group of three or more.

Step-by-Step Solution

1
Identify the total number of items being compared in the context of the sentence.
The sentence explicitly specifies a comparison between exactly two items ('two structural audit reports').
The choice between comparative and superlative modifier forms depends strictly on whether two entities or more than two entities are being compared.
2
Apply the rule governing degrees of adjective modification for two items.
Select the comparative modifier 'more' rather than the superlative modifier 'most'.
In standard formal English, the comparative degree ('more') is required when comparing two items, whereas the superlative degree ('most') is reserved for three or more items.

Question 166Question →

Which of the following options represents the correct passive form of the active sentence below?

"The regulatory commission ought to have taken over the distressed bank much earlier."

Show answer & explanation

Answer: The distressed bank ought to have been taken over by the regulatory commission much earlier.

Answer

The distressed bank ought to have been taken over by the regulatory commission much earlier.
The correct answer properly converts the active modal perfect verb phrase 'ought to have taken over' into its corresponding passive form 'ought to have been taken over'. It retains the subject-object shift, the passive marker 'been', and the prepositional particle 'over' without introducing grammatical errors.

Step-by-Step Solution

1
Identify the object of the active sentence
The direct object is 'the distressed bank', which becomes the subject of the passive sentence.
In passive transformation, the receiver of the action is shifted to the subject position.
2
Transform the modal perfect verb phrase while retaining the phrasal particle
'ought to have taken over' becomes 'ought to have been taken over'.
The passive form of a modal perfect construction (modal + have + past participle) requires inserting 'been' before the past participle verb and keeping the prepositional particle intact.
3
Add the agent clause
'by the regulatory commission' is appended following the passive verb phrase.
The original subject 'the regulatory commission' acts as the agent of the passive clause.

Question 167Question →

Which of the following pronouns correctly completes the sentence below?

'One of the major telecommunication companies operating in the country has lost _____ operational license following a regulatory audit.'

Show answer & explanation

Answer: its

Answer

The correct option is 'its' because the singular subject 'One' requires a singular possessive pronoun.
The sentence specifies 'One' as the singular head antecedent. Therefore, the possessive pronoun modifying 'operational license' must be singular and neuter ('its').

Step-by-Step Solution

1
Identify the true grammatical antecedent in the subject clause.
The head of the subject phrase is the singular indefinite pronoun 'One', not the plural noun 'companies' within the prepositional modifier 'of the major telecommunication companies'.
Modifiers inside prepositional phrases do not change the number of the core head antecedent.
2
Determine the gender and number of the required pronoun.
The antecedent refers to a single corporate entity, requiring a 3rd-person singular neuter possessive determiner ('its').
Pronouns must agree in number, person, and gender with their grammatical antecedent.

Question 168Question →

The new manager congratulated the team members _____ their outstanding performance during the annual audit. Which of the following prepositions correctly completes the sentence?

Show answer & explanation

Answer: on

Answer

The preposition 'on' correctly completes the sentence because the verb 'congratulate' requires 'on' to indicate the achievement being celebrated.
In standard English, the verb 'congratulate' takes the dependent preposition 'on' to introduce the achievement or occasion being celebrated ('congratulate someone on something').

Step-by-Step Solution

1
Identify the main verb requiring a dependent preposition.
The head verb is 'congratulated'.
Dependent prepositions are governed by the specific verb or expression preceding them.
2
Determine the standard prepositional collocation for 'congratulate'.
The correct pattern is 'congratulate someone ON something'.
'On' is the standard preposition that connects 'congratulate' to the cause of congratulation.

Question 169Question →

More than one candidate _______ failed the preliminary screening exercise conducted by the board. Which of the options correctly completes the sentence?

Show answer & explanation

Answer: has

Answer

The correct verb form is 'has'.
The expression 'more than one' followed by a singular countable noun ('candidate') strictly requires a singular verb according to the rules of grammatical concord. Therefore, the singular present perfect auxiliary 'has' is correct.

Step-by-Step Solution

1
Identify the subject structural pattern in the sentence.
The subject structure begins with the quantifier phrase 'More than one' modifying the singular noun 'candidate'.
Determining the head subject structure dictates whether a singular or plural verb is grammatically required.
2
Apply the specific rule of grammatical concord for 'more than one'.
'More than one' followed directly by a singular noun takes a singular verb.
Although semantically 'more than one' implies a plural quantity, formal English syntax requires agreement with the singular noun 'candidate'.
3
Select the correct singular auxiliary verb to form the present perfect tense.
'has' completes the phrase correctly as 'has failed'.
'has' is singular present perfect, agreeing perfectly with 'More than one candidate'.

Key Concept

Concord with 'More than one'
Question 170Question →

During a severe tropical storm analysis, a meteorologist drafted several technical summaries. Which of the following sentences correctly avoids a dangling modifier?

Show answer & explanation

Answer: Having thoroughly calibrated the telemetry sensors, the lead meteorologist processed the atmospheric data without delay.

Answer

Having thoroughly calibrated the telemetry sensors, the lead meteorologist processed the atmospheric data without delay.
The correct sentence properly places the introductory participial modifier 'Having thoroughly calibrated the telemetry sensors' adjacent to its logical subject, 'the lead meteorologist'. This ensures a clear and grammatically sound connection between the modifier and the agent performing the action.

Step-by-Step Solution

1
Identify the introductory participial phrase in the sentence.
The phrase is 'Having thoroughly calibrated the telemetry sensors'.
An introductory participial phrase functions as an adjectival modifier and must describe the subject immediately following it.
2
Determine the logical actor who performed the action in the modifying phrase.
The person who calibrated the sensors is 'the lead meteorologist'.
Sensors cannot be calibrated by data, power surges, or abstract actions.
3
Select the option that places the logical actor as the subject of the main clause.
The sentence placing 'the lead meteorologist' directly after the comma correctly avoids a dangling modifier.
Proper modifier alignment requires the noun being modified to act as the explicit grammatical subject of the main clause.

Question 171Question →

Complete the following sentence with the most appropriate modal verb: 'After working continuous night shifts for a week, the doctor _____ take a complete rest.' Which of the following modal auxiliaries correctly completes the sentence?

Show answer & explanation

Answer: must

Answer

The correct option is 'must'.
The word 'must' is a modal auxiliary verb used to express strong necessity or advice. It is correctly followed by the bare infinitive verb 'take' without an intervening 'to'.

Step-by-Step Solution

1
Identify the required grammatical function in the sentence context.
The sentence requires a modal auxiliary to express strong necessity or recommendation.
The doctor's fatigue after working continuous night shifts necessitates rest.
2
Apply the rule governing modal auxiliary verbs and main verb complements.
Standard modal auxiliaries (must, should, can, might) take a bare infinitive without 'to'. Furthermore, double modals cannot be stacked.
Modal verbs directly precede the base form of the main verb.
3
Select the grammatically correct modal verb.
The form 'must' correctly pairs with the base verb 'take'.
'Must' is grammatically accurate and fits the context of obligation/necessity.

Key Concept

Modal auxiliaries are followed directly by the bare infinitive form of a main verb (without 'to') and cannot be combined with other modal auxiliaries.
Question 172Question →

During the annual commendation ceremony, the principal congratulated the debate team _____ their outstanding performance in the national competition. Which of the following prepositions correctly completes the sentence?

Show answer & explanation

Answer: on

Answer

The preposition 'on' correctly completes the sentence because the verb 'congratulate' strictly collocate with 'on'.
In standard English grammar, the verb 'congratulate' takes the dependent preposition 'on' (e.g., 'congratulate someone on an achievement'). Therefore, 'on' is the only grammatically correct option.

Step-by-Step Solution

1
Identify the head verb in the sentence requiring a dependent preposition.
The verb is 'congratulated'.
Certain English verbs require specific dependent prepositions to complement their meaning correctly.
2
Determine the standard prepositional collocation for 'congratulate'.
The correct combination is 'congratulate [someone] on [something]'.
Standard British and English grammatical rules dictate that 'on' follows 'congratulate' when introducing the achievement or occasion.

Question 173Question →

Read the sentence below carefully:

'The governing council appointed Dr. Adeleke the new vice-chancellor of the university.'

What is the grammatical function of the underlined noun phrase?

Show answer & explanation

Answer: Object complement

Answer

The underlined noun phrase functions as an object complement.
In English grammar, complex transitive verbs such as 'appoint', 'elect', 'make', 'consider', and 'declare' take a direct object followed by an object complement. In the given sentence, 'Dr. Adeleke' is the direct object, and the underlined noun phrase 'the new vice-chancellor of the university' completes the predicate by describing the capacity or role in which Dr. Adeleke is appointed. Therefore, its grammatical function is an object complement.

Step-by-Step Solution

1
Analyze the main verb and sentence structure
The verb 'appointed' is a complex transitive verb that requires both a direct object and an element that completes the object's meaning.
Identifying verb subcategorization helps determine whether subsequent noun phrases function as objects or complements.
2
Identify the direct object
'Dr. Adeleke' is the direct object receiving the action of the verb.
The entity directly affected by the appointment is the person being appointed.
3
Determine the relationship between 'Dr. Adeleke' and 'the new vice-chancellor of the university'
The phrase 'the new vice-chancellor of the university' renames and defines the status assigned to 'Dr. Adeleke'.
A noun phrase that renames or describes a direct object following a complex transitive verb serves as an object complement.

Question 174Question →

In the sentence below, what is the grammatical function of the underlined noun phrase?

*The university Senate appointed Professor Danjuma the dean of the new faculty.*

Show answer & explanation

Answer: Object complement of the verb "appointed"

Answer

Object complement of the verb "appointed"
The noun phrase 'the dean of the new faculty' functions as an object complement because it follows the direct object 'Professor Danjuma' and completes the predicate structure of the complex-transitive verb 'appointed'.

Step-by-Step Solution

1
Analyze the main clause structure and identify the verb and its direct object.
The subject is 'The university Senate', the main verb is 'appointed', and the direct object receiving the action is 'Professor Danjuma'.
Determining the direct object establishes the syntactic target of the subsequent noun phrase.
2
Determine the syntactic relationship between 'Professor Danjuma' and 'the dean of the new faculty'.
The noun phrase 'the dean of the new faculty' completes the predication by describing the new status assigned to the direct object.
A noun phrase that renames or describes a direct object to complete the sense of a complex-transitive verb functions as an object complement.

Complete the sentence below by filling in the blank with the most appropriate verb form.

Fill in the blanks below

By the time the rescue team finally arrived at the scene, the injured hikers in the freezing cave for over twelve hours.
Show answer & explanation

Answer

had been waiting (or had waited)
The correct verb form 'had been waiting' accurately expresses an action that started in the past and continued up until another specified past action ('arrived'). The prepositional phrase 'for over twelve hours' highlights duration, requiring the past perfect aspect.

Step-by-Step Solution

1
Analyze the time frame and sequence of events in the sentence.
Two past events are described: the hikers waiting in the cave, and the arrival of the rescue team.
The clause 'By the time the rescue team finally arrived' sets a definite past reference point using the simple past tense ('arrived').
2
Determine the correct tense and aspect needed for the earlier action with duration.
The past perfect continuous ('had been waiting') or past perfect ('had waited') must be used.
When an action began before a past point in time and continued continuously up to or through that past moment, the past perfect continuous (or past perfect simple for duration) is grammatically required.

All candidates present their original identification cards before entering the examination hall, as failure to do so will result in immediate disqualification.
Show answer & explanation

Answer

must
The modal auxiliary verb 'must' is required because the sentence conveys a mandatory rule where compliance is compulsory.

Step-by-Step Solution

1
Analyze the context of the sentence to determine the intended modality.
The phrase 'failure to do so will result in immediate disqualification' indicates a strict requirement or compulsory duty.
Contextual clues in official rules dictate whether a modal verb should convey permission, obligation, possibility, or ability.
2
Select the modal auxiliary verb that denotes mandatory requirement.
The modal verb 'must' expresses strong, inescapable obligation mandated by an authority or rule.
'Must' is the correct modal verb used to express absolute necessity and requirement.

Fill in the blank with the grammatically correct form of the verb to complete the sentence below.

Fill in the blanks below

Neither the manager nor the employees satisfied with the new work schedule announced last week.
Show answer & explanation

Answer

were
According to the principle of proximity concord, when compound subjects are connected by 'neither... nor', the verb must agree in number with the subject closest to it. Here, the noun phrase nearest to the blank is 'the employees' (plural). Combined with the past tense time marker 'last week', the correct plural past tense verb is 'were'.

Step-by-Step Solution

1
Identify the subject structure connected by correlative conjunctions.
The sentence uses 'neither... nor' to connect two subjects: 'the manager' (singular) and 'the employees' (plural).
Under the rule of proximity concord, when subjects are joined by 'neither... nor', the verb must agree with the subject closest to it.
2
Identify the subject closest to the verb blank and determine its number and tense context.
The closest subject is 'the employees', which is plural, and the context 'last week' indicates past tense.
A plural subject in the past tense requires the plural past tense verb form 'were'.

Complete the sentence below by filling in the blank with the most appropriate modal verb phrase that correctly expresses an unnecessary past action.

Fill in the blanks below

Since attendance at the optional workshop was not mandatory, the delegates registered in advance, yet many spent hours doing so.
Show answer & explanation

Answer

need not have
The modal auxiliary perfect construction 'need not have' followed by the past participle 'registered' correctly conveys that the delegates performed an action that was completely unnecessary given the non-mandatory nature of the event.

Step-by-Step Solution

1
Analyze the context of the sentence
The sentence describes an action ('registered in advance') that occurred even though there was no requirement or obligation ('attendance... was not mandatory').
Identifying the temporal context (past) and communicative intent (absence of obligation for an action that took place) is essential to choosing the correct modal form.
2
Select the modal auxiliary form for past lack of necessity
The structure 'need not have + past participle' specifically denotes that an action was performed in the past despite being unnecessary.
Using 'must not have' would denote negative past deduction, while 'should not have' would denote past criticism, neither of which matches the non-mandatory contextual clue.

than
In standard clause structure, the correlative adverbs 'no sooner' must be followed by the conjunction 'than' to connect the main clause with the subordinate clause detailing an immediate subsequent event.

Step-by-Step Solution

1
Identify the introductory correlative structure in the sentence.
The main clause begins with the inverted expression 'No sooner had'.
Correlative conjunctions function in strict, fixed grammatical pairs to link clauses.
2
Select the correct paired conjunction to introduce the subsequent clause.
The standard paired conjunction for 'no sooner' is 'than'.
In standard English grammatical structure, 'no sooner' requires 'than' to connect the time clause describing an immediate succeeding event.

Question 180Question →

Complete the sentence with the correct verb form to complete the unreal past construction.

Fill in the blanks below

During the press briefing, the spokesperson remarked that the minister would rather the press secretary the official statement before the news went public yesterday.
Show answer & explanation

Answer

had released (or had issued / had published)
In English grammar, when the expression 'would rather' is followed by a subject and a clause referring to a past time frame (indicated here by 'yesterday'), the past perfect tense (had + past participle) must be used to express an unfulfilled past preference or regret.

Step-by-Step Solution

1
Analyze the syntactic structure and temporal reference of the sentence.
The clause is introduced by 'would rather' followed by a new subject ('the press secretary') and includes an explicit past time marker ('yesterday').
When 'would rather' is followed by a subordinate clause expressing a preference about a past event, the subjunctive rule requires the verb to be in the past perfect tense.
2
Select the correct past perfect verb structure.
The auxiliary verb 'had' combined with the past participle form of an appropriate main verb (such as 'had released' or 'had issued') must be used.
Using simple past ('released') would incorrectly signal a present or future hypothetical situation, while present perfect ('has released') violates sequence of tenses in unreal past constructions.
