When an earthquake suddenly struck Ramya’s village, she shouted
to tell the people that they should come out of their houses and go
into the fields, since there were no trees, electric poles or building
nearby. Later she went about organizing help for the injured and
people who had been rendered homeless.
i. Why did Ramya ask everyone to go into the fields? (2)
ii. Which values do we learn from Ramya?

Answer:
Buildings in the future could be isolated from earthquakes by being placed behind rows of trees. That’s according to physicists in France, who have shown that certain seismic waves, known as Love waves, could be diverted away from the Earth’s surface as they pass through a forest containing trees of a certain height. The forest acts like a metamaterial – an artificial structure usually used to steer electromagnetic radiation around objects.
