'She has finished her assignment'. (change voice)

Appeared in: WCL Staff Nurse - 2022

Explanation

The original sentence is in the Present Perfect tense, indicated by the verb 'has finished'.
The correct rule for converting a Present Perfect active voice sentence to passive voice is: Object + has/have + been + Past Participle (V3) + by + Subject.
Following this rule, the object 'her assignment' becomes the subject, the verb becomes 'has been finished', and the subject 'She' becomes the agent 'by her'.
This correctly transforms the sentence to 'Her assignment has been finished by her', preserving the original tense.

Option B: This option uses the Simple Past Passive tense ('was finished'), which incorrectly changes the tense of the original sentence.
Option C: This is the Present Perfect Continuous tense and is still in the active voice. It changes both the tense and the voice incorrectly.
Option D: This option uses the Simple Past Passive tense and omits the agent ('by her'). The tense is incorrect.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Active to Passive Voice Conversion (Present Perfect Tense) as background academic context rather than a clinical decision trigger.
This question tests general English grammar, not a clinical topic.
Strong grammar skills are essential for nurses for clear and professional communication.
Accurate communication is critical for patient charting, handover reports, and providing patient education to avoid misunderstandings.

How to Approach the Question

First, identify the tense of the original sentence. The verb 'has finished' indicates the Present Perfect tense.
Next, identify the subject ('She') and the object ('her assignment') of the active sentence.
Recall the specific rule for changing the voice for that tense. For Present Perfect, the passive form is 'has/have + been + past participle'.
Construct the passive sentence: The object becomes the new subject, apply the passive verb form, and add the original subject as the agent using the preposition 'by'.
Compare your constructed sentence ('Her assignment has been finished by her') with the given options to find the exact match.
