Question

[1]. Read the following passage carefully and answer the question.

Passage: A volcano forms where hot, molten rock from below the earth's crust finds a weak point and pushes upward. When pressure builds, an eruption can release lava, ash and gases with enormous force, reshaping hillsides and burying fields in a single night. Yet volcanoes also create. Over centuries, cooled lava breaks down into rich, fertile soil that farmers prize, and new islands can rise from the sea where eruptions continue under water. Scientists now monitor volcanoes with seismometers and gas sensors, watching for tremors and swelling ground that warn of an eruption. Living near a volcano is therefore a bargain with nature: danger in the short term, fertility and new land over the long term.
