Complete the sentence below by supplying the correct form of the verb in brackets.

Fill in the blanks below

The environmental advocacy group emphasized that it was high time the state ministry [enforce] strict regulatory penalties on industrial polluters.
Show answer & explanation

Answer

enforced
The correct verb form is 'enforced' because the construction 'it is/was high time' followed by a subject clause requires the simple past tense (past subjunctive). This structure expresses urgency or a delayed obligation regarding a present or future action.

Step-by-Step Solution

1
Analyze the main clause structure and introductory expression.
The sentence contains the fixed unreal past expression 'it was high time' followed by a subject noun phrase ('the state ministry').
Expressions such as 'it is time', 'it is high time', or 'it is about time' when followed by a personal subject require the subjunctive simple past tense form of the verb.
2
Inflect the base verb in brackets 'enforce' into the correct grammatical form.
The simple past inflection of 'enforce' is 'enforced'.
The past form 'enforced' is required by the unreal past construction to convey that the action is overdue, even though the semantic time reference pertains to the present or immediate future.

Question 2142Question →

The chief archivist, together with her research assistants, published _____ comprehensive catalogue of historical manuscripts in the university journal. Which of the following pronouns correctly completes the sentence?

Show answer & explanation

Answer: her

Answer

The singular possessive determiner 'her' correctly completes the sentence.
The primary antecedent is the singular noun phrase 'The chief archivist'. Expressions introduced by 'together with' are parenthetical prepositional phrases that do not change the number of the subject. Consequently, the singular possessive pronoun 'her' properly agrees with the singular antecedent.

Step-by-Step Solution

1
Identify the primary antecedent in the subject position.
The head noun of the subject is 'chief archivist' (singular, female).
Intervening phrases introduced by quasi-conjunctions such as 'together with', 'along with', or 'as well as' are prepositional modifiers and do not alter the singular grammatical number of the subject.
2
Select the pronoun form that maintains proper agreement.
The singular feminine possessive determiner 'her' is required to modify 'comprehensive catalogue'.
The pronoun must agree in number, gender, and syntactic function with its singular antecedent.

Key Concept

Pronoun-antecedent agreement with subjects followed by quasi-conjunction phrases ('together with')
Question 2143Question →

Which of the following options correctly transforms the sentence below into the passive voice?

'Ought the lead investigator to have turned over the crucial evidence to the prosecuting counsel before trial?'

Show answer & explanation

Answer: Ought the crucial evidence to have been turned over to the prosecuting counsel by the lead investigator before trial?

Answer

Ought the crucial evidence to have been turned over to the prosecuting counsel by the lead investigator before trial?
The correct passive sentence maintains exact structural alignment with the active question: the interrogative modal 'Ought' leads the sentence, followed by the new subject ('the crucial evidence'), the passive modal perfect auxiliary sequence ('to have been turned over'), the prepositional complement, the agent ('by the lead investigator'), and the temporal modifier. Crucially, the phrasal particle 'over' is preserved.

Step-by-Step Solution

1
Identify the active subject, verb phrase, direct object, and auxiliary structure.
Subject: 'the lead investigator'; Verb phrase: 'ought to have turned over' (modal verb 'ought' + perfect infinitive 'to have turned' + phrasal particle 'over'); Direct object: 'the crucial evidence'.
Accurate grammatical identification is required before re-ordering clause elements.
2
Promote the active direct object to the passive subject position following the interrogative modal.
The structure becomes 'Ought the crucial evidence...'
In passive interrogatives, the primary auxiliary verb remains at the front while the new subject follows it immediately.
3
Convert the active perfect verb phrase into its corresponding passive perfect form while retaining phrasal verb particles.
'to have turned over' becomes 'to have been turned over'.
The passive form of a modal perfect infinitive requires 'to have been' + past participle, and phrasal verb particles must be strictly retained.
4
Attach the agent prepositional phrase and remaining adjuncts.
'...to the prosecuting counsel by the lead investigator before trial?'
Preserves complete semantic information and thematic roles of the original sentence.

Question 2144Question →

Complete the sentence below by filling in the blank with the grammatically correct verb form to maintain subject-verb concord.

Fill in the blanks below

Either the chief executive officer or his deputies attending the international economic summit next week.
Show answer & explanation

Answer

The correct verb to fill the blank is 'are'.
When two subjects are connected by 'Either... or', the principle of proximity concord applies. This rule dictates that the verb must agree with the subject closest to it. Here, the plural noun 'deputies' is closest to the blank, requiring the plural verb form 'are'.

Step-by-Step Solution

1
Identify the structure of the subject in the sentence.
The subject consists of two elements connected by the correlative conjunction pair 'Either... or': 'the chief executive officer' (singular) and 'his deputies' (plural).
Correlative conjunctions link two separate noun phrases acting as compound subjects.
2
Apply the rule of proximity concord for correlative subjects.
The verb must agree in number with the subject noun nearest to it, which is 'deputies' (plural).
When subjects are joined by 'either... or' or 'neither... nor', proximity concord dictates that the verb agrees with the closer subject element.
3
Select the appropriate auxiliary verb for continuous present/future action.
The plural auxiliary verb 'are' correctly matches the plural noun 'deputies'.
'Are' fulfills both the requirement for plural agreement and continuous aspect for an upcoming event.

Question 2145Question →

Select the word that has the same end rhyme sound as plaid.

Show answer & explanation

Answer: glad

Answer

glad
The target word 'plaid' is transcribed phonetically as /plæd/, featuring the short monophthong /æ/ sound. Among the given options, 'glad' is pronounced as /ɡlæd/, sharing the exact same rime /æd/, which creates a true phonetic rhyme.

Step-by-Step Solution

1
Determine the International Phonetic Alphabet (IPA) transcription of the target word.
The target word 'plaid' is transcribed as /plæd/.
Rhyme in Oral English is determined strictly by matching the nuclear vowel sound and terminal consonant sound, not by spelling.
2
Transcribe and analyze the end sound of each given option.
'played' (/pleɪd/), 'glad' (/ɡlæd/), 'blade' (/bleɪd/), and 'paid' (/peɪd/).
Identifying the vowel phoneme in each option isolates the true phonetic match from visual eye-rhyme distractors.
3
Match the target word's terminal phonemes with the corresponding option.
/plæd/ matches /ɡlæd/ in the /æd/ sound ending.
Both words contain the short monophthong /æ/ followed by the voiced alveolar plosive /d/.

Question 2146Question →

Fill in the blank in the sentence below using the correct past modal auxiliary form of the verb in parentheses to express that an action was performed unnecessarily.

Fill in the blanks below

Because all conference papers were uploaded to the portal prior to the event, the coordinator (print) paper copies for the attendees.
Show answer & explanation

Answer

need not have printed (or needn't have printed)
The modal construction 'need not have printed' (or 'needn't have printed') is used in English to indicate that an action was completed in the past, but in retrospect, it was unnecessary.

Step-by-Step Solution

1
Determine the modality required by the sentence context.
The context describes an action (printing paper copies) that was carried out in the past even though it was not required because the papers were already available digitally.
The expression of a past action performed without necessity requires the modal structure 'need not have + past participle'.
2
Formulate the correct verb phrase using the verb 'print'.
Combining 'need not have' with the past participle 'printed' yields 'need not have printed' or its contracted form 'needn't have printed'.
This structure accurately distinguishes between an action done unnecessarily ('need not have printed') and one that was avoided because it was unnecessary ('did not need to print').

Question 2147Question →

During yesterday's briefing, the spokesperson announced that the director _______ the revised policy document earlier that morning. Which of the following verb forms correctly completes the sentence?

Show answer & explanation

Answer: had approved

Answer

The correct verb form is 'had approved'.
The verb form 'had approved' correctly employs the past perfect tense to signal an action completed prior to another past time marker ('announced') in indirect reporting.

Step-by-Step Solution

1
Analyze the time sequence between the main clause and the subordinate clause.
The main reporting verb 'announced' is in the simple past tense, and the action of approving took place 'earlier that morning' before the announcement.
When an action is completed prior to another past event in reported speech, the past perfect tense is required.
2
Identify the past perfect verb form.
The past auxiliary 'had' combined with the past participle 'approved' yields 'had approved'.
This establishes proper tense backshift and clear aspectual order.

Question 2148Question →

Which of the following sentences demonstrates correct cumulative adjective ordering and avoids modifier placement errors?

Show answer & explanation

Answer: The museum curator acquired a valuable ancient rectangular bronze artifact, which was meticulously restored last week.

Answer

The sentence reading 'The museum curator acquired a valuable ancient rectangular bronze artifact, which was meticulously restored last week.' is grammatically correct.
The correct choice places the cumulative adjectives in the precise natural English sequence (Opinion: valuable → Age: ancient → Shape: rectangular → Material: bronze) and uses the adverb 'meticulously' correctly without creating dangling participial modifiers.

Step-by-Step Solution

1
Evaluate the order of cumulative adjectives preceding 'artifact'.
The adjectives are ordered as Opinion (valuable) → Age (ancient) → Shape (rectangular) → Material (bronze).
English grammatical convention (OSASCOMP) dictates that opinion precedes age, shape, and material.
2
Examine modifying phrases and adverbial usage across all options.
The introductory modifier in the passive construction creates a dangling modifier in one option, while another incorrectly uses a homophonic adverb.
Participial phrases must clearly and logically modify the agent undertaking the action.

Question 2149Question →

In the sentence below, a gap is left to test subject-verb agreement:

"The principal, together with the class teachers, ______ present at the annual school inter-house sports competition."

Which verb form correctly completes the sentence?

Show answer & explanation

Answer: was

Answer

The singular verb 'was' correctly completes the sentence.
When a singular head subject is followed by quasi-conjunctions or prepositional phrases such as 'together with', 'along with', or 'in addition to', the grammatical number of the subject remains singular. Therefore, the singular past-tense verb 'was' is the only correct choice.

Step-by-Step Solution

1
Identify the head noun of the grammatical subject.
The main subject is 'The principal', which is singular.
Phrases introduced by 'together with', 'along with', or 'as well as' are prepositional modifiers, not conjunctions, so they do not make the subject plural.
2
Match the verb number with the singular head noun in the past tense.
The singular verb 'was' agrees grammatically with 'The principal'.
A singular head subject demands a singular verb regardless of any plural nouns appearing inside intervening parenthetical phrases.

Question 2150Question →

Read the sentence below:

'Dr. Ezekwesili, alongside her lead researchers, ______ preparing to present the clinical trial results, although neither of the participating hospitals ______ yet verified the raw data.'

Which option correctly fills the gaps to satisfy the rules of grammatical concord?

Show answer & explanation

Answer: is / has

Answer

The correct option is 'is / has'.
The choice featuring 'is / has' correctly identifies that parenthetical modifiers such as 'alongside...' do not pluralize the main subject ('Dr. Ezekwesili'), requiring the singular verb 'is'. Furthermore, it correctly enforces formal concord by assigning the singular verb 'has' to the singular indefinite pronoun 'neither'.

Step-by-Step Solution

1
Analyze the subject of the first clause and identify parenthetical expressions
The subject is 'Dr. Ezekwesili' (singular). The phrase 'alongside her lead researchers' is a parenthetical prepositional modifier, not a coordinating conjunction like 'and'.
Intervening phrases introduced by 'alongside', 'as well as', 'together with', or 'in addition to' do not alter the grammatical number of the subject head noun.
2
Determine the correct verb for the first gap
The singular subject 'Dr. Ezekwesili' requires the singular verb 'is'.
Subject-verb concord dictates agreement between the singular head noun and its verb, ignoring intervening plural nouns.
3
Analyze the subject of the subordinate clause and apply indefinite pronoun rules
The subject head of the second clause is 'neither', which is a singular indefinite pronoun.
Indefinite pronouns such as 'neither', 'either', 'each', and 'everyone' take singular verbs in formal examination grammar regardless of any following plural prepositional phrase ('of the participating hospitals').
4
Select the correct verb for the second gap
The singular subject 'neither' requires the singular auxiliary verb 'has'.
Matching the verb to 'hospitals' is an error of proximity.

Question 2151Question →

Consider the direct speech sentence below:

"If the auditor had arrived yesterday as scheduled, would we have completed the financial review today?" the chief accountant asked the manager.

Which of the following options correctly transforms this sentence into reported speech?

Show answer & explanation

Answer: The chief accountant inquired of the manager whether, if the auditor had arrived the day before as scheduled, they would have completed the financial review that day.

Answer

The statement is correctly reported as: The chief accountant inquired of the manager whether, if the auditor had arrived the day before as scheduled, they would have completed the financial review that day.
The correct response accurately transforms the direct question into indirect speech by introducing the question with 'whether', keeping the third conditional verb forms intact, changing the first-person pronoun 'we' to 'they', and backshifting both temporal adverbs ('yesterday' → 'the day before', 'today' → 'that day').

Step-by-Step Solution

1
Identify sentence type and reporting verb
The direct sentence is a yes/no question containing a third conditional clause, framed by the past-tense reporting verb 'asked'.
Direct yes/no questions require the introductory conjunction 'if' or 'whether' when converted into indirect speech.
2
Apply tense and modal stability rules for unreal past conditionals
The past perfect condition ('had arrived') and past modal construction ('would have completed') remain unchanged.
Third conditional structures (unreal past) do not backshift further in reported speech.
3
Transform pronouns and time adverbs
'we' shifts to 'they', 'yesterday' shifts to 'the day before' (or 'the previous day'), and 'today' shifts to 'that day'.
Direct speech time references and first-person plural pronouns must shift to align with the reporter's context.

Question 2152Question →

Provide a word that correctly completes the sentence by identifying a word containing the specified diphthong sound.

Fill in the blanks below

The diphthong sound /ɔɪ/, which is present in 'boy', is also found in the word .
Show answer & explanation

Answer

Any word containing the /ɔɪ/ diphthong, such as 'coin', 'voice', 'choice', 'boil', or 'point', correctly completes the sentence.
The sound /ɔɪ/ is a prominent English diphthong heard in words like 'boy', 'coin', 'voice', 'choice', 'oil', and 'boil'. Providing any word that features this glide correctly satisfies the phonetic requirement.

Step-by-Step Solution

1
Identify the target diphthong sound.
The symbol /ɔɪ/ represents an open-mid back rounded vowel gliding towards a near-close near-front unrounded vowel, as in 'boy' or 'rejoice'.
Understanding the phonetic glide helps isolate words with identical vowel quality.
2
Select a word containing this specific phonetic sound.
Words like 'coin' (/kɔɪn/), 'voice' (/vɔɪs/), or 'boil' (/bɔɪl/) share the exact /ɔɪ/ diphthong.
These words feature the correct sound glide rather than pure monophthongs or other diphthongs.

Fill in the blanks below

Direct statement: "I can complete the project today," Joy said.
Indirect statement: Joy said that she complete the project that day.
Show answer & explanation

Answer

could
When transforming direct speech into indirect speech with a past tense reporting verb such as 'said', present modal verbs must backshift to their corresponding past tense forms. Therefore, 'can' correctly changes to 'could'.

Step-by-Step Solution

1
Identify the main modal verb in the direct speech statement.
The direct statement uses the present tense modal auxiliary verb 'can'.
Direct speech reflects the exact words spoken by the speaker in the present tense.
2
Apply tense backshifting for reported speech following a past tense reporting verb ('said').
'can' changes to 'could'.
When the reporting verb is in the past tense, present modal verbs must backshift to their past forms ('can' becomes 'could').

Question 2154Question →

Which conjunction appropriately fills the blank in the sentence below?

Fill in the blanks below

The university senate agreed to fund only such interdisciplinary research projects align directly with the national development priorities.
Show answer & explanation

Answer

The correct conjunction to fill the blank is 'as'.
The conjunction 'as' correctly completes the correlative construction 'such... as' when introducing a clause that defines or restricts a specified class of items.

Step-by-Step Solution

1
Analyze the main clause and identify the correlative antecedent.
The main clause contains the determiner 'such' modifying 'interdisciplinary research projects'.
The inclusion of 'such' sets up a correlative relationship with the upcoming subordinate clause.
2
Determine the required relative connector for the subordinate clause.
The clause introduces a restrictive property defining the category of projects.
In standard formal English, when 'such' introduces a category, it pair correlatively with 'as' (not 'that' or 'which') to introduce the defining clause.

Question 2156Question →

Consider the direct speech statement: "Have you decided which course to study at the university next year?" the counselor asked the candidate.

Which of the following options correctly converts this statement into reported speech?

Show answer & explanation

Answer: The counselor asked the candidate if he had decided which course to study at the university the following year.

Answer

The correct reported speech sentence is: 'The counselor asked the candidate if he had decided which course to study at the university the following year.'
The correct choice accurately changes the direct yes/no question into a reported statement using the conjunction 'if', backshifts the present perfect verb 'have decided' into the past perfect 'had decided', and updates the time expression 'next year' to 'the following year'.

Step-by-Step Solution

1
Identify the clause type and appropriate reporting conjunction
The direct speech is a yes/no question starting with 'Have you...', so the reporting conjunction must be 'if' or 'whether' without using 'that'.
Indirect questions requiring a yes/no answer require 'if' or 'whether' to join the reporting clause to the reported clause.
2
Backshift the main verb tense
The present perfect auxiliary verb 'have decided' shifts back to the past perfect 'had decided'.
When the reporting verb ('asked') is in the past tense, present tense verbs must shift back into their corresponding past forms.
3
Convert temporal adverbs
The time expression 'next year' changes to 'the following year' or 'the year after'.
Adverbs of time referring to future periods relative to the moment of speaking must shift relative to the point in time being reported.

Question 2158Question →

During the judicial commission of inquiry, the lead counsel asserted that had the chief auditor ________ the original financial statements prior to the release of the report, the discrepancy would have been detected immediately. Which verb form correctly completes the sentence?

Show answer & explanation

Answer: reviewed

Answer

The verb form 'reviewed' correctly completes the sentence as the past participle required in an inverted third conditional clause.
The sentence constructs an inverted third conditional expressing an unreal action in the past ('had the chief auditor reviewed... the discrepancy would have been detected'). In standard English grammar, when an 'if' clause in the past perfect is inverted, the auxiliary verb 'had' moves before the subject, leaving the main verb in its past participle form ('reviewed').

Step-by-Step Solution

1
Identify the clause structure and conditional type
The sentence uses an inverted third conditional clause ('had the chief auditor ________') paired with the result clause containing 'would have been detected'.
Recognizing conditional sentence patterns determines the tense and aspect requirements for both clauses.
2
Analyze the inverted past perfect requirement
Inverted third conditionals omit 'if' and front the auxiliary verb 'had' before the subject ('had + subject + past participle').
The fronted auxiliary 'had' requires a non-finite past participle main verb to complete the verb phrase.
3
Select the verb form matching the past participle inflection
The past participle of 'review' is 'reviewed', completing the clause 'had the chief auditor reviewed'.
Using any other form (bare infinitive, present tense, or repeated auxiliary) results in grammatical error or redundancy.

Fill in the blanks below

The commission of inquiry, having resolved all internal disagreements among its members, released final report to the government.
Show answer & explanation

Answer

its
The word 'its' is correct because the antecedent 'commission of inquiry' acts as a single, unanimous body when issuing the report.

Step-by-Step Solution

1
Identify the antecedent for the required pronoun in the sentence.
The antecedent is the collective noun phrase 'The commission of inquiry'.
The pronoun in the blank replaces or refers back to the commission that released the report.
2
Analyze the context to determine whether the collective noun operates as a single entity or as separate individuals.
The phrase 'having resolved all internal disagreements' shows that the commission is now acting as a single, unified body.
When a collective noun functions as a single unified unit, it requires a singular neuter pronoun.
3
Select the possessive pronoun that correctly agrees in number and gender with the singular collective noun.
The correct singular possessive pronoun is 'its'.
In formal standard English, singular non-human collective antecedents take 'its'.

Question 2160Question →

Which of the options lettered A to D contains the SAME CONSONANT SOUND as the one represented by the underlined letter in the word 'casual'?

Show answer & explanation

Answer: beige

Answer

The word 'beige' contains the same consonant sound (/ʒ/) as the underlined letter in 'casual'.
The underlined letter 's' in 'casual' represents the voiced postalveolar fricative consonant sound /ʒ/. The word 'beige' contains the exact same sound, realized through the spelling 'ge' at the end of the word.

Step-by-Step Solution

1
Identify the target consonant sound
The underlined letter 's' in 'casual' represents the voiced postalveolar fricative sound, phonetically transcribed as /ʒ/.
Accurate phonetic identification of the target word is essential before examining the options.
2
Analyze the phonetic composition of each option
'fissure' uses /ʃ/, 'beige' uses /ʒ/, 'chivalry' uses /ʃ/, and 'censor' uses /s/.
Determining the precise consonant sound produced by the relevant letters in each candidate word isolates the matching sound.
3
Select the option with the matching sound
The word 'beige' ends with the /ʒ/ sound (spelled 'ge'), matching 'casual'.
Both words share the identical /ʒ/ sound despite using different orthographic representations ('s' vs 'ge').
