In advanced English syntax and diathesis alternation, the conversion of active constructions into passive voice involves complex structural reconfigurations, case-marking adjustments, and thematic role mapping. Consider the following four advanced propositions regarding active and passive voice conversion:I. When converting a ditransitive clause with two internal arguments (e.g., *'The board offered the candidate a lucrative contract'*), both the direct object and the indirect object can theoretically be promoted to the subject position in the passive voice, yielding two distinct grammatical variants (*'A lucrative contract was offered the candidate'* vs. *'The candidate was offered a lucrative contract'*, though the latter is stylistically more prevalent in standard registers).II. Intransitive verbs that completely lack a direct object—such as *'vanish'*, *'occur'*, or *'collapse'*—can regularly undergo passive transformation provided that an expletive dummy subject (*'it'* or *'there'*) is inserted into the matrix subject slot to satisfy the Extended Projection Principle.III. In sentences featuring a causative or perception matrix verb followed by a bare infinitive in the active voice (e.g., *'The supervisor made the technician inspect the turbine'*), the passive transformation requires the reinstatement of the to-infinitive marker, resulting in *'The technician was made to inspect the turbine by the supervisor'*.IV. Middle constructions (such as *'This fabric washes easily'* or *'The novel reads well'*) exhibit active morphological marking while possessing passive-like semantic valency, where the underlying patient is promoted to subject position and the agent is obligatorily suppressed, rendering the explicit inclusion of a 'by-agent' phrase ungrammatical.Identify the option that correctly evaluates the grammatical, syntactic, and semantic validity of propositions I, II, III, and IV according to standard English grammar and Passive voice theory.
