1791. Read the passage and answer the question. In regions with clear seasons, a tree adds one growth ring each year. In warm, wet years the ring is wide; in cold or dry years it is narrow. By matching the patterns of wide and narrow rings in very old wood, scientists can work out when a wooden object was made and learn about past climates. This method is called dendrochronology. What would a very narrow tree ring most probably show?

      कA very old tree खA year of poor growing conditions गA year with heavy rainfall घA tree that was recently cut down

1792. Read the passage and answer the question. The common cuckoo does not build a nest of its own. Instead, the female lays an egg in the nest of another species, such as a reed warbler, often removing one of the host's eggs first. Soon after hatching, the cuckoo chick pushes the other eggs out of the nest. The host parents then feed it as if it were their own, even when it grows much larger than they are. In the last sentence, what does 'it' in 'feed it as if it were their own' refer to?

      कthe host's egg खthe reed warbler's nest गthe cuckoo chick घthe female cuckoo

1794. Read the passage and answer the question. The Arctic fox is well suited to its changing surroundings. In winter its thick fur is white, which makes it very hard to see against the snow. When the snow melts in summer, it sheds this coat and grows a thinner brown or grey one that matches the rocks and plants of the tundra. Why does the Arctic fox change the colour of its fur?

      कTo keep cool in winter खTo attract a mate in summer गTo show that it is fully grown घTo stay hidden in each season

Which statement about the people in Antarctica is supported by the passage?

      कThey stay only for a limited time. खThey were born at the research stations. गMost of them are tourists. घThey live there with their families.

1796. Read the passage and answer the question. In the 1860s, Louis Pasteur showed that gently heating wine killed the microbes that made it go sour, without spoiling its taste. The process, later named pasteurisation after him, is now used mainly for milk. Unlike boiling, it changes the flavour very little. However, pasteurised milk must still be kept cool, because the process does not destroy every bacterium. According to the passage, what was Pasteur's heating method first used to protect?

      कMilk खWine गWater घCheese

1798. Read the passage and answer the question. In 1844 Samuel Morse sent a message by electric telegraph along a wire from Washington to Baltimore. Messages were sent as a code of short and long signals, later called dots and dashes. Before the telegraph, news could travel no faster than a rider on a horse or a ship at sea. Within a few decades, cables crossed continents and even the ocean floor. What is the main point of the sentence beginning 'Before the telegraph'?

      कHorses and ships were no longer used after 1844. खNews was rarely sent before 1844. गThe telegraph made it possible for news to travel faster than people could. घMorse code was first used by sailors.

1799. Read the passage and answer the question. Before the 1920s, a diagnosis of type 1 diabetes usually meant that the patient would die within a few years. In 1921, at the University of Toronto, Frederick Banting and his student assistant Charles Best managed to extract insulin from the pancreas of dogs. Within a year, a fourteen-year-old boy became the first person to be treated successfully with it. Today most insulin is made by genetically modified bacteria and yeast. According to the passage, how is most insulin produced today?

      कFrom the pancreas of dogs खFrom the blood of donors गBy the University of Toronto घBy genetically modified microorganisms
