- Read the passage and answer to the questions (1-5): Marie Curie, was born in Warsaw on November 7, 1867. She became involved in student activism and found it prudent to leave Warsaw, then in the part of Poland dominated by Russia, for Cracow, which at that time was under Austrian rule. In 1891, she went to Paris to continue her studies at the Sorbonne where she obtained Licentiateships in Physics and the Mathematical Sciences. She met Pierre Curie, Professor in the School of Physics in 1894 and in the following year they were married. She succeeded her husband as Head of the Physics Laboratory at the Sorbonne, gained her Doctor of Science degree in 1903, and following the tragic death of Pierre Curie in 1906, she took his place as Professor of General Physics in the Faculty of Sciences, the first time a woman had held this position. The discovery of radioactivity by Henri Becquerel in 1896 inspired the Curies in their brilliant researches and analyses which led to the isolation of polonium, named after the country of Marie's birth, and radium. Curie developed methods for the separation of radium from radioactive residues in sufficient quantities to allow for its characterization and the careful study of its properties, therapeutic properties in particular. She received many honorary degrees and honorary memberships of learned societies throughout the world. Together with her husband, she was awarded half of the the Nobel prize for Physics in 1903, for their study into the spontaneous radiation discovered by Becquerel, who was awarded the other half of the prize. In 1911 she received a second Nobel Prize, this time in Chemistry, in recognition of her work in radioactivity she also received, jointly with her husband, the Davy Medal of the Royal Society in 1903 and in 1921, President Harding, presented her with one gram of radium in recognition of her service of science.Madame Curie was awarded Ph.D in ________.

- Read the following passage and select the best answer for each of the questions that follow. Had it not been for Matthew Henson, Robert E. Peary might not have reached the North Pole. Henson, a black man, was the only person to accompany Peary on all of the explorer's Polar expeditions. At first Peary doubted that Henson could endure the arctic climate. During the eighteen years these two attempted to reach the Pole, Henson's unfailing good humor and courage helped Peary to move on. Eskimos of Smith Sound greeted Henson as a brother, welcomed him into their stone igloos, and taught him their difficult language. Soon Henson became the most proficient of Peary's men, not only in speaking Innuit but also in handling a dog team. On later expeditions it was he who taught greenhorns how to drive a dog team and how to survive in the sub-zero climate. Beloved by the Eskimos, who called him "Miy Paluk", he persuaded them to accompany Peary into the uncharted regions where they believed evil spirits dwelled. On a nearly disastrous excursion across the ice cap in 1895, Henson twice saved Peary's life. Again and again Henson proved that he was capable of endurance and achievement, the final test coming in 1909 when he accompanied Peary and four Eskimos on the last lap of the successful dash to the pole. Greenhorns were -

- At this stage of civilization, when many nations are brought in to close and vital contact for good and evil, it is essential, as never before, that their gross ignorance of one another should be diminished, that they should begin to understand a little of one another's historical experience and resulting mentality. It is the fault of the English to expect the people of other countries to react as they do, to political and international situations. Our genuine goodwill and good intentions are often brought to nothing, because we expect other people to be like us. This would be corrected if we knew the history, not necessarily in detail but in broad outlines, of the social and political conditions which have given to each nation its present character. According to the author 'Mentality' of a nation is mainly product of it's -
