Select the correct passive form of the given sentence.
“The engineer is testing the system.”
Show answer & explanation
Correct answer: A
Explanation
Correct Answer: The system is being tested by the engineer.
Explanation
• The given sentence is in the Present Continuous Tense (Active Voice: Subject + is/am/are + V-ing + Object).
• To change a present continuous sentence into the Passive Voice, use the structure: Object + is/am/are + being + V3 (past participle) + by + Subject.
• Here, 'The system' is singular, so it takes 'is' followed by 'being' and the past participle 'tested'.
Quick Tip: Whenever the active verb ends in -ing (continuous tense), the passive form must include being followed by the past participle (V3).
