If the dinosaur fossil is shown to be related to other dinosaurs of the same period in South America, it will also support the idea that South America and Antarctica were once linked together. 1. It is only recently that _____. A) important scientific studies about the Southern Hemisphere have been carried out. B) scientists have been seriously interested in fossils. C) a dinosaur fossil has been discovered in Antarctica. D) some new facts about the Northern Hemisphere have come to light. E) Antarctica has been discovered. 2. One can understand from the passage that _____. A) dinosaurs, at one time in the past, lived in both hemispheres. B) dinosaurs were in fact, more commonly found in the Southern Hemisphere. C) scientists had long since realized that dinosaurs had actually lived in Antarctica. D) the dinosaur fossil, discovered in Antarctica, was significantly different from those found in other continents. E) the discovery of the dinosaur fossil in Antarctica was actually of little importance to scientists. 3. It is hoped that the discovery of the dinosaur fossil in Antarctica _____. A) would contribute significantly to our knowledge of the Northern Hemisphere. B) will throw further light on the existence of dinosaurs in the past. C) would lead to further similar discoveries in the Southern Hemisphere. D) could answer the question whether South America and Antarctica were originally connected. E) will attract more scientists to this type of work
