Directions : Read the passage given below and answer the questions that follow (Q. No. 320 to 325) 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 degrees Fahrenheit? 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 fiber 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 probelm for some time and had little success, until Kwolek had a breakthrough. Kwolek and her group were synthesizing or creating fibers 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 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 drumheads, reeds and speaker cones. And it is used in protective gear like motorcycle afety jackets, glove 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 froces and it is estimated that by 1990, half of all police officers in America wore bulletproof vests daily. By 2006, there were over 2000 documented police vest 'saves', or instances where officers were protected form deadly wounds by wearing bulletproof vests. For which of the following characteristics is Kevlar known?

निर्देश (प्र.सं. H-15 से H-20 तक) : इस खंड में नीचे दिए गए गद्यांश से सम्बन्धित प्रश्न दिए गए हैं। सही विकल्प चुनकर उत्तर पत्रक में अंकित कीजिये। विकास क्रम में पशुता हमारा जन्मसिद्ध अधिकार है और मनुष्यता हमारे युग-युगांतर के अनवतर अध्यवसाय से अर्जित अमूल्य निधि। इसी से हम अपने पूर्व स्वप्न के लिए, सामंजस्यपूर्ण आदर्श के लिए और भावनाओं के लिए प्राण की बाजी लगाते रहे हैं। जब हम से ऐसा करने की शक्ति शेष नहीं रह जाती तब हम एक मिथ्या दम्भ के साथ पशुता की ओर लौट चलते हैं क्योंकि वहाँ पहुँचने के लिए न किसी पराक्रम की आवश्यकता है और न साधन की। हम अपने शरीर को निश्चेष्ट छोड़कर हिमालय के शिखर से पाताल की गहराई तक सहज ही लुढ़कते चले आ सकते हैं। परंतु उसे ऊंचाई के सहस्र अंशो तक पहुँचने में हमारे पाँव काँपने लगेंगे, साँस फूलने लगेगी और आँखों के सामने अंधेरा छा जाएगा। मनुष्य पशुता की ओर कब लौटता है?
