Question

1. Read the passage given below and answer the question that follows: (5) Surgical Instruments Designed Due to Necessity Necessity, they say, is the mother of invention. And Indian doctors have been quite creative when hamstrung by few or no tools to perform specific surgeries. They simply design it themselves at one-fourth the price they are sold abroad. In fact, some of their innovations are priced at as much as hundreds of dollars abroad. Take 47-year-old Dr Burjor P Banaji, pioneer of Lasik surgery in India. He's invented over a dozen surgical instruments. When this senior eye surgeon at Max Eye Care started Lasik, there were few surgeons doing it worldwide and no specific instruments were available either. "As I want things super-perfect, I designed a whole slew of instruments that made my surgery more efficient," says Banaji. The most popular instruments are Banaji Lasik Shield and Banaji Lasik Spatula and Canulae. "It was simple. I had the designs in my head. Putting them down on paper was the simplest thing," he says. Instruments manufacturers and large multinationals in the US snapped them up. "They would send me computer generated drawings which I would correct and send back. Their level of execution was astounding. Within two weeks of the designs being finalised, the instruments were in the world market." His instruments are priced at hundreds of dollars each in the US, and are also sold in Switzerland, South America, Korea, Eastern Europe, Africa and Japan. They're available in India at a fraction of the price. --Shobha John/TNN a) Why have some Indian doctors created their own surgical tools? i) They have no tools to perform specific surgeries. ii) They have a hamstring problem. iii) The tools they get from abroad cost four times as much. iv) They can sell these tools at a very high price. b) What has Dr Burjor P Banaji created? i) Lasik surgery ii) Max Eye Care Centre iii) Two surgical instruments called Banaji Lasik Shield and Banaji Lasik Spatula and Canulae iv) More than a dozen instruments for operating on the eye. c) Where does Dr Banaji get the instruments manufactured? i) India (ii) the United States of America (iii) Switzerland (iv) Japan d) The term hamstrung refers to …………………………… i) Restricted (ii) helped (iii) harmed (iv) liberated e) What does the phrase slew of instruments refer to? i) a wide range of instruments (ii) instruments used for slaying iii ) tools of a similar nature (iv) surgical instruments​
