1. Read the passage carefully and answer the questions that follow:(5)1. For more than four exhausting years, the Polish-born Marie Curie and her husband, Pierre, worked in a largedilapidated wooden shed near their Paris lodgings. This shed, which was like a hothouse in summer anddraughty and cold in winter, was the place where they spent the happiest years of their lives. It was here on aSeptember night in 1902 that they finally discovered the radioactive element that they named 'radium' fromthe Latin word radius, meaning ‘ray'.2. Radium provided the first effective treatment for some types of cancer, destroying the diseased human cellsby bombarding them with radioactive particles.3. The Curies had spent the historic day pouring measures of purified pitchblende into some 6,000 evaporatingbowls. Marie Curie believed that the black mineral ore contained a completely new and dynamic elementwhose rays could destroy unhealthy body tissues. By constantly filtering and re-filtering the pitchblende, shehoped that the elusive element would crystallize in the bowls.4. When they went home that evening the miracle had still not occurred. Then, just as they were about toto bed, Marie decided to have another look at the particles in the bowls. She and Pierre hurried through thedimly-lit streets.5. They let themselves into the darkened shed-with its rows of wooden tables and clutter of laboratoryequipment--and Marie asked Pierre not to light the lamps. They moved cautiously forward and there, allaround them, rays of light came from inside the small glass-covered bowls, Marie turned to her husband andsaid quietly, 'Do you remember the day you said to me: "I should like radium to have a beautiful colour?" LookLook!6. The bowls that lined the tables and the shelves on the walls gave off a soft, bluish-purple glow.Page 1of3Questions:(a) Who researched on radium and where?(b) How did they discover radium?(c) Why did they decide to name the element so?(d) Why was the discovery of radium important?(e) Find a word from the passage which means the same as 'falling to pieces'.​
