Which of the following options is the most suitable conversion of the following sentence into Passive Voice?
Does she check all the final calculations before the launch?
Show answer & explanation
Correct answer: A
Explanation
Conversion from active to passive voice:
The original sentence is in the Present Simple Tense (indicated by "Does").
"All the final calculations" becomes the new subject.
In passive voice for the Present Simple, we use is/am/are + Past Participle (V3). Since "calculations" is plural, we use "Are".
"Check" becomes "checked".
"She" changes to the object pronoun "her" preceded by "by."
Passive voice: Are all the final calculations checked by her before the launch?
