In the passive voice, the object (the students) becomes the subject, and the verb changes to "was/were + past participle."

5. Application-Based Questions (Subject: Science)

Question: Why does a ship made of iron float, while an iron nail sinks in water?

Answer: A ship is hollow and shaped so that it displaces a large volume of water. According to Archimedes' principle, the buoyant force on it equals the weight of the water it displaces, which is enough to balance the ship's weight. An iron nail is solid and displaces very little water, so its weight is greater than the buoyant force, and it sinks.

The solutions include a similar variety of questions for every chapter and subject.
