- 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.Marie Curie received one gram of radium_______ .

- Read the passage and answer to the questions (1-5): Unsafe levels of pesticides are present in around half of the vegetables and more than a quarter of fruits sold in the capital's markets. A research team came up with the findings after collecting and testing food samples from a few randomly selected capital markets. The survey report read that nearly 40% of 82 samples contained banned pesticides such as DDT, Aldrin, Chlordane and Heptachlor. The amounts of pesticides in these samples were found to be 3 to 20 times greater than the standard limits. Around 50% of vegetables and 25% of fruits were found to be contaminated with an unsafe level of pesticides. Analysing more than 30 samples of turmeric powder, the team also found that nearly 30% of the samples contained traces of Lead Chromate, which can be fatal if swallowed or inhaled. Using the HPLC method, 66 samples were analyzed for the presence of fomaldehyde, Adulteration was thereby detected in samples of coriander, mango and fresh shrimps. Samples of chicken and fish contained traces of antibiotics. High microbial populations were found in several samples of pasteurized milk, indicating poor processing procedures by the manufacturers. Samples of cucumber and street foods also showed high microbial populations, suggesting widespread contamination in the water supply. Experts suggest that instead of focusing only on the end products, the issue should be addressed at the root level. Better monitoring and supervision in the production process farmer, transport, wholesale, and retail trader - are mandatory for minimizing food adulteration. Adulterated food products are reportedly the cause behind thousands of people suffering from fatal diseases like cancer, kidney failure and heart problems. The Parliament had enacted a Food Safety Act; but, was yet to prepare the necessary rules.Select the inappropriate sequence.
