Question

Below is given sentence in active/passive voice. Out of the four alternative suggested, select one which best expresses the same sentence in passive/active voice:
"The waiter filled the glasses with water."

• A. The glasses filled with water by the waiter.
• B. The glasses were filled with water by the waiter.
• C. The waiter was filled the glasses with water.
• D. The water were filled in the glasses by waiter.

Hint:

Always track the singular or plural status of your new passive subject. Here, glasses is strictly plural, which means it requires were, not was. This helps you quickly rule out incorrect choices. Active $V_2 \rightarrow$ Passive ($\text{was/were} + V_3$)

Answer 1

The Correct Option is B

Step 1: Read the active sentence.
The waiter filled the glasses with water.
Step 2: Pick out the parts.
Subject is the waiter, verb is filled (simple past), and object is the glasses, with the phrase with water added.
Step 3: Recall the passive rule.
In the passive, the object moves to the front and we use was or were plus the past participle.
Step 4: Choose the auxiliary.
The new subject the glasses is plural, so we need were, giving were filled.
Step 5: Build the full sentence.
The glasses were filled with water by the waiter.
Step 6: Reject the others.
Option A drops the auxiliary, C makes the waiter the receiver, and D wrongly uses were with the uncountable water, so option B is correct.
\[ \boxed{\text{B. The glasses were filled with water by the waiter.}} \]
