Select the correct passive form of the given sentence.
“The scientist discovered a new planet.”
Show answer & explanation
Correct answer: A
Explanation
Correct Answer: A new planet was discovered by the scientist.
Explanation:
• The given sentence is in the Simple Past Tense (Active Voice: Subject + V2 + Object).
• To convert a Simple Past sentence into Passive Voice, the structure is: Object + was/were + V3 (past participle) + by + Subject.
• Here, 'a new planet' is a singular object, so it takes 'was discovered'.
Quick Tip: Tense never changes during voice transformation. Simple past stays in the past tense form (was/were + V3).
