Choose the best option to complete each sentence, then check your answers.
Despite initial opposition from local heritage groups, the historical landmark ___ completely transformed by the end of next year to accommodate the new high-speed rail terminal.
The time expression 'by the end of next year' specifies a completed future action, requiring the Future Perfect Passive ('will have been'). The active form 'will have' lacks the passive auxiliary 'been', making the sentence ungrammatical.
The marine sanctuary was established primarily to protect fragile coral ecosystems from ___ damaged by heavy commercial fishing equipment.
Prepositions such as 'from' must be followed by a gerund, and because the subject receiving the action is the ecosystems, the passive gerund 'being' is required. Using the infinitive 'to be' directly after a preposition is ungrammatical in standard English.
By the time the international trade summit concluded last night, a binding agreement ___ ratified by all participating delegates.
The time clause 'By the time... concluded' sets a past reference point, so an action completed prior to that point requires the Past Perfect Passive ('had been'). 'Has been' incorrectly uses the present perfect for a completed past timeframe.
The newly developed therapeutic compound appears ___ approved by the regulatory board during last month's session, despite lingering safety concerns.
The verb 'appears' takes a 'to'-infinitive, and because the approval occurred in the past ('during last month's session'), the Perfect Passive Infinitive ('to have been') is required. The simple passive infinitive 'to be' fails to express a completed past event.
While the complex software update ___ by the engineering team, users experienced temporary disruptions in network services.
The conjunction 'While' indicates an ongoing background action in the past, requiring the Past Continuous Passive ('was being installed') because the update is receiving the action. 'Was installing' is active voice and illogically implies the update was performing the installation.
The ancient manuscript is believed ___ by monastic scribes during the early eighth century.
In passive reporting constructions with present matrix verbs ('is believed'), a completed historical action requires the Perfect Passive Infinitive ('to have been written'). 'To be written' incorrectly implies a present or open state rather than a finished past event.
During the financial review, several major accounting discrepancies were found to ___ overlooked by the internal auditing team for months.
The construction 'were found to' requires an infinitive complement; since the overlooking occurred prior to the finding, the Perfect Passive Infinitive ('have been') is required. 'Had been' is a finite past perfect verb and cannot follow the infinitive particle 'to'.
For the past three decades, traditional agricultural techniques in the valley ___ replaced by automated farming technologies.
The time expression 'For the past three decades' establishes a duration originating in the past and continuing to the present, requiring the Present Perfect Passive ('have been steadily'). 'Were steadily' restricts the time frame to a closed past period.
The rare artifacts might not ___ preserved so meticulously had the museum curators not regulated the storage temperature.
This third conditional structure with an inverted condition ('had the museum curators not...') requires 'might not have been' in the result clause to express a past unfulfilled passive event. 'Had been' cannot follow a modal auxiliary like 'might'.
At present, several key urban regeneration projects in the capital ___ delayed due to unforeseen supply chain bottlenecks.
The adverbial phrase 'At present' signals an ongoing current state, requiring the Present Continuous Passive ('are being'). 'Are having' does not form a passive structure with the past participle 'delayed'.
Many department heads strongly resisted ___ relocated to regional offices during the corporate restructuring process.
The verb 'resist' takes a gerund object, so the passive form must be 'being' followed by the past participle ('being relocated'). Infinitive forms like 'to be' cannot complement the verb 'resist'.
The legal team insisted on having all submitted evidence ___ by an accredited forensic expert before the trial commenced.
The causative structure 'have + object + past participle' requires the passive participle ('evaluated') when the object ('evidence') receives the action. Active structures like 'evaluate' or 'evaluating' disrupt this causative passive rule.
Global economic growth is predicted ___ heavily influenced by fluctuations in energy prices over the coming decade.
The passive structure 'is predicted' takes a 'to'-infinitive complement; because the reference is to continuous or future influence, the simple passive infinitive ('to be') is required. 'Being' cannot follow 'is predicted' as a complement.
Long before the formal treaty was signed, diplomatic relations ___ severed by a series of border disputes.
The temporal marker 'Long before... was signed' indicates that the severing of relations happened prior to another past event, requiring the Past Perfect Passive ('had been'). 'Have been' incorrectly uses the present perfect for an action completed in the distant past.
The research team denied ___ informed about the safety violations prior to the publication of the report.
The verb 'deny' requires a gerund complement; to show a passive action completed prior to the denial, the Perfect Passive Gerund ('having been') is required. 'To have been' uses an infinitive structure, which is incorrect after 'deny'.
