5. statements (1-5) are T (true), F (false) or DS (doesn't say). The War of the Worlds, by HG Wells, is one of the most famous science-fiction stories of all time.

Not many people are interested at first, but then the cylinder unscrews and a strange creature emerges. These are aliens from Mars, and after a short while they have created huge machines, equipped with heat-rays and chemical weapons, which attack humans and rain death upon the land. As people attempt to escape from London and the surrounding counties, the narrator must find a way to stay alive and be reunited with his wife. Will humans finally defeat the Martians? Will the narrator survive and find his wife? The exciting plot keeps the reader absorbed to the very end.
