The regulatory framework might revise by the committee during the session.
The regulatory framework might be revised by the committee during the session.
The regulatory framework might have been revised by the committee during the session.
The regulatory framework has been revised by the committee during the session.

Correct answer: The regulatory framework might have been revised by the committee during the session.

Solution

In passive voice, the object “the regulatory framework” becomes the subject. Since the active sentence uses the modal perfect form “might have revised,” the passive form must be “might have been revised.” Therefore, option 3 is correct.

Identify the sentence from the passage that is in the passive voice: Read the passage given below and answer the questions that follow: The metamorphosis of a moth exemplifies one of nature's most intricate and fascinating biological transitions. The life cycle commences with the deposition of delicate eggs, typically concealed along the veins of leaves, ensuring immediate sustenance once they hatch. Upon emergence, the larva — or caterpillar — enters a stage of persistent consumption, voraciously feeding on plant matter to accelerate its growth. Throughout this period, it experiences successive molts, discarding its inflexible exoskeleton to accommodate its enlarging structure. This intense feeding phase is indispensable for accumulating the energy necessary for the forthcoming metamorphosis. The progression into the pupal stage, enclosed within a chrysalis, represents an extraordinary biological transformation. Within this enclosure, the caterpillar’s tissues are methodically dismantled and reorganized into entirely new anatomical structures; wings, antennae, and compound eyes develop through a refined mechanism termed histogenesis. After this concealed reconstruction concludes, the adult moth emerges, its fragile wings requiring expansion with hemolymph and sufficient drying before flight can occur. Once airborne, the moth’s existence is primarily devoted to reproduction, thereby ensuring the continuation of the species before its ephemeral lifespan ends. Although frequently idealized, the moth’s life cycle illustrates a demanding narrative of adaptation, endurance, and evolutionary precision, providing profound insight into ecological equilibrium.
