गद्यांश : Direction : Read the following passage carefully and answer the questions that follow by selecting the correct/most appropriate options.
Did you know that there is a fiber that is as flexible and lightweight as nylon yet five times stronger than steel ? Did you know that this fabric is resistant to temperatures higher than 500°F ? Did you know that a woman invented this fiber ? This miraculous fabric is called Kevlar and it is used to make everything from body armor to musical instruments.
The year was 1964. There were gasoline shortages due to conflict in the Middle East. A Polish - American chemist named Stephanie Louise Kwolek was working for DuPont, an American Chemical Company. She and her group were trying to make a lightweight, yet durable fibre to be used in tires. Lighter tires would allow vehicles to get better gas mileage, but the tires had to be strong enough to resist the wear and tear of the road. They had been working on the problem for some time and had little success, until Kwolek had a breakthrough.
Kwolek and her group were synthesizing or creating fibres to test. During one of the steps in the process, Kwolek created a milky white solution by mixing two chemicals that were often used in the process. This solution was usually thrown away, but Kwolek convinced one of the technicians to help her test it. They were amazed to discover that the fabric that Kwolek had created was not only more durable than nylon, it was more durable than steel.
Kwolek had invented Kevlar. Kevlar is a remarkable fabric known for its strength and durability. Since its invention it has found its way into a wide variety of products. Kevlar is used in sporting equipment like bike tires, bowstrings and tennis racquets. It is used in musical instruments like drum heads, reeds and speaker cones. And it is used in protective gear like motorcycle safety jackets, gloves and shoes. However, Kevlar is best known for its ability to stop bullets.
Richard Armellino created the first Kevlar bulletproof vest in 1975. It contained 15 layers of Kevlar, which could stop handgun and shotgun bullets. The vest also had a steel plate over the heart, which made the vest strong enough to stop rifle rounds. Vests like Armellino's were quickly picked up by police forces and it is estimated that by 1990, half of all police officers in America wore bulletproof vests daily. By 2006, there were over 2,000 documented police vest 'saves', or instances where officers were protected from deadly wounds by wearing bulletproof vests.

This solution was usually thrown away, but Kwolek convinced one of the technicians to help her test it. They were amazed to discover that the fabric that Kwolek had created was not only more durable than nylon, it was more durable than steel.
Kwolek had invented Kevlar. Kevlar is a remarkable fabric known for its strength and durability. Since its invention it has found its way into a wide variety of products. Kevlar is used in sporting equipment like bike tires, bowstrings and tennis racquets. It is used in musical instruments like drum heads, reeds and speaker cones. And it is used in protective gear like motorcycle safety jackets, gloves and shoes. However, Kevlar is best known for its ability to stop bullets.
Richard Armellino created the first Kevlar bulletproof vest in 1975. It contained 15 layers of Kevlar, which could stop handgun and shotgun bullets. The vest also had a steel plate over the heart, which made the vest strong enough to stop rifle rounds. Vests like Armellino's were quickly picked up by police forces and it is estimated that by 1990, half of all police officers in America wore bulletproof vests daily. By 2006, there were over 2,000 documented police vest 'saves', or instances where officers were protected from deadly wounds by wearing bulletproof vests.
What product was Kwolek trying to improve when she invented Kevlar ?

Man who is believed to have evolved from apes, is a curious mixture of varied motives. He is not only the subject of needs, but is also their creator. He not only seeks to satisfy his needs but also caters to his desire for beauty and grace. He is eager to satisfy his passion for more and more knowledge. Although in a general way, the maxim 'necessity is the mother of invention' is true, it is by no means the whole truth. Man is something much greater than an intelligent being using his intellect to make newer inventions from time to time.
He has within him a spirit which is ever exhorting him to cut down his needs and learn to be happy with what he has. The real purpose underlying this maxim lies in its utility in the worldly sense. It tells us to be up and doing, not to be passive in our attitude to life. It asks us not to remain slaves of old habits and ways of life. We must face the new situations with a creative mind. Every new difficulty, every new problem, which confronts us in life, can be tackled successfully with the spirit of inventiveness.
