Select the option that expresses the given sentence in active voice.
Most of Earth's surface is covered by water.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Water covers most of Earth's surface.
-
The original sentence "Most of Earth's surface is covered by water" is in passive voice because the subject ("Earth's surface") is acted upon by the verb ("is covered").
-
In contrast, the selected option "Water covers most of Earth's surface" is in active voice because the subject ("Water") performs the action of covering ("covers") the object ("most of Earth's surface").
-
Therefore, the selected option transforms the sentence from passive to active voice.
