Zorluk: Çok zorActive and Passive Voice Transformation

Read the active sentence provided below and complete the corresponding passive sentence by filling in the blank with the appropriate verb phrase that preserves the exact tense, aspect, and modal meaning of the original statement. What is the correct passive verb sequence to complete the sentence?

Active: The defense ministry must have passed on the classified coordinates to the ground commanders.

Passive: The classified coordinates must {{blank_1}} on to the ground commanders by the defense ministry.

Cevap:The classified coordinates must 【have been passed】 on to the ground commanders by the defense ministry.

Cevap

have been passed
The active sentence employs a modal perfect construction ('must have passed') followed by the phrasal verb particle 'on'. In transforming a modal perfect verb into the passive voice, the passive marker 'been' must be inserted between the auxiliary 'have' and the past participle 'passed', producing 'must have been passed on'. Because the modal 'must' and particle 'on' are already provided in the frame surrounding the blank, the exact missing verb sequence is 'have been passed'.

Adım Adım Çözüm

1
Analyze the active verb structure and identify its constituent parts.
The active verb phrase is 'must have passed on', composed of the modal auxiliary 'must', the perfect infinitive 'have passed', and the phrasal verb prepositional particle 'on'.
Identifying the active verb structure is necessary to determine how to build the corresponding passive auxiliary chain without altering mood or tense.
2
Derive the passive construction for a modal perfect verb sequence.
The passive form of 'modal + have + past participle' is 'modal + have + been + past participle'. Applying this rule yields 'must have been passed'.
Converting an active modal perfect verb to passive voice requires introducing the passive auxiliary 'been' immediately before the main verb's past participle.
3
Match the derived passive verb sequence against the pre-filled template.
Since 'must' and 'on' are already present in the prompt frame, supplying 'have been passed' completes the passive sentence correctly as 'must have been passed on'.
Ensures no required auxiliary is omitted and no extraneous particles are duplicated.
