I'm taking a test and have to guess the right answer to the question after the article. Article: The dodo is among the most famous extinct creatures, and _ for human-caused extinction events. Despite its bad name, and the fact that the species was alive during recorded human history, little is actually known about how this animal lived, looked, and behaved. A new study of the only known complete skeleton from a single bird takes advantage of modern 3-D laser scanning technology to open a new window into the life of this famous extinct bird. The study was presented at the 74th Annual Meeting of the Society of Vertebrate Paleontology in Estrel, Berlin. Leon Claessens, Associate Professor at the College of the Holy Cross, and lead researcher on the study said that, "the 3-D laser surface scans we made of the fragile dodo skeletons enable us to reconstruct how the dodo walked, moved and lived to a level of detail that has never been possible before. There are so many outstanding questions about the dodo bird that we can answer with this new knowledge." A complete dodo skeleton, found by an amateur collector and barber, Etienne Thirioux, on the island of Mauritius between 1899 and 1917, has remained unstudied, even though it is the only complete dodo skeleton from a single individual bird known to exist. All other skeletons are incomplete combinations, meaning that they are gathered from more than one individual. In addition, Thirioux constructed a second, partially combined skeleton, which contains many bones that also belong to a single bird. "Being able to examine the skeleton of a single, individual dodo, which is not made up from as many individual birds as there are bones, as is the case in all those other combined skeletons, truly allows us to appreciate the way the dodo looked and see how tall or fat it really was," said Juilan Hume, of the Natural History Museum UK, a co-author on the study. The scans were performed on site in Durban, South Africa, and allow examination of the biology of this mysterious extinct bird in detail for the first time. Using the newest digital tools and techniques, the... Question: The researchers study the dodo skeleton to find out _ . Options: A: ways to save the dodo B: the dodo's living habits C: the bird's natural habitat D: the cause of the dodo's extinction

I'm taking a test and have to guess the right answer to the question after the article. Article: The journey two naval officers made some time ago to the very deepest point on the earth makes us realize how much of the world still remains to be explored. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball called a "bathyscaphe" to find out if there are any ocean currents or sings of life. It was necessary to set out early, so that the "bathyscaphe" would come to the surface in daylight, and so be easily found by the mother ship which would be waiting for it. The drivers began preparations at dawn and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water. In time, the temperature dropped to freezing-point and the men trembled inside the ball. They kept in touch with the mother ship by telephone describing how they felt. Then, at a depth of 3,000 feet, the men were surprised by a sudden, loud noise, even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the "bathyscaphe" touched the soft ocean floor raising a big cloud of "dust" made up of different kinds of small, dead sea animals. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite uncontrolled by the very large water-pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the weak but clear voices of the officers wre heard on the mother ship. After a stay of thirty minutes the men began their journey up, arriving three hours later, _ . Question: The journey to the bottom of the sea helped us to realize that _ . Options: A: much of the world hasn't yet been explored B: there are not any sings of life at the bottom of the sea C: strong water-pressure has great effect on fish D: powerful lights cannot be turned on at the ocean floor
