The questions in this section are based on what is stated or implied in the passage given below. For each question, choose the option that most accurately and completely answers the question.
The words invention and Innovation are closely linked, but they are not interchangeable. The inventor is a genius who uses his intellect, imagination, time and resources to create something that does not exist. But this invention may or may not be of utility to the masses. It is the enterprising innovator who uses various resources, skills and time to make the invention available for use. The innovator might use the invention as it is, modify it or even blend two or more inventions to make one marketable product. A great example is that of the iPhone which is a combination of various inventions.
If an invention is the result of countless trials and errors, so can be the case with an innovation. Not every attempt to make an invention is successful. Not every innovation sees the light of the day. Benjamin Franklin had the belief that success doesn‘t come without challenge, mistake, and in a few cases failure.
One of the world‘s most famous innovators, Steve Jobs says, ―Sometimes when you innovate, you make mistakes. It is best to admit them quickly and get on with improving your other innovations.
Thus, inventors and innovators have to be intrepid enough to take risks; consider failures as stepping stones and not stumbling blocks.
Some inventions are the result of a keen observation or a simple discovery. The inventor of Velcro, also called the zipless zipper, is the Swiss engineer George de Mestral. He was hiking in the woods when he found burrs clinging to his clothes and his dog‘s fur. Back at home, he studied the burrs. He discovered that each burr was a collection of tiny hooks which made it cling on to another object. A few years later, he made and patented the strips of fabric that came to us as Velcro.
The world of inventions and innovations is a competitive one. But the race does not end here; it is also prevalent in the case of getting intellectual property rights. There have been inventors who failed to get a single patent while there have been some who managed to amass numerous patents in their lifetime. Thomas Edison had 1,093 patents to his credit!
We relate the telephone with Alexander Graham Bell. It is believed that around the same time, Antonio Meucci had also designed the telephone, but due to lack of resources and various hardships, he could not proceed with the patent of his invention. It is also believed that Elisha Gray had made a design for the telephone and applied for the patent at the U.S. patent office on the same day as Graham Bell did. By sheer chance, Graham‘s lawyer‘s turn to file the papers came first. Hence, Graham was granted the first patent for the telephone.
It is not easy, and at times almost impossible, for an inventor to be an innovator too. There are very few like Thomas Edison who graduated from being an incredible inventor to a successful manufacturer and businessman with brilliant marketing skills.
While innovations that have helped to enhance the quality of life are laudable, equally laudable are the inventions that laid the foundation of these very innovations.


When people who are talking don’t share the same culture, knowledge, values, and assumptions, mutual understanding can be especially difficult. Such understanding is possible through the negotiation of meaning. To negotiate meaning with someone, you have to become aware of and respect both the differences in your backgrounds and when these differences are important. You need enough diversity of cultural and personal experience to be aware that divergent world views exist and what they might be like. You also need the flexibility in world view, and a generous tolerance for mistakes, as well as a talent for finding the right metaphor to communicate the relevant parts of unshared experiences or to highlight the shared experiences while demphasizing the others. Metaphorical imagination is a crucial skill in creating rapport and in communicating the nature of unshared experience. This skill consists, in large measure, of the ability to bend your world view and adjust the way you categorize your experiences. Problems of mutual understanding are not exotic; they arise in all extended conversations where understanding is important.
When it really counts, meaning is almost never communicated according to the CONDUIT metaphor, that is, where one person transmits a fixed, clear proposition to another by means of expressions in a common language, where both parties have all the relevant common knowledge, assumptions, values, etc. When the chips are down, meaning is negotiated: you slowly figure out what you have in common, what it is safe to talk about, how you can communicate unshared experience or create a shared vision. With enough flexibility in bending your world view and with luck and charity, you may achieve some mutual understanding.
Communication theories based on the CONDUIT metaphor turn from the pathetic to the evil when they are applied indiscriminately on a large scale, say, in government surveillance or computerized files. There, what is most crucial for real understanding is almost never included, and it is assumed that the words in the file have meaning in themselves—disembodied, objective, understandable meaning. When a society lives by the CONDUITmetaphor on a large scale, misunderstanding, persecution, and much worse are the likely products.
Later, I realized that reviewing the history of nuclear physics served another purpose as well: It gave the lie to the naive belief that the physicists could have come together when nuclear fission was discovered (in Nazi Germany!) and agreed to keep the discovery a secret, thereby sparing humanity such a burden. No. Given the development of nuclear physics up to 1938, development that physicists throughout the world pursued in all innocence of any intention of finding the engine of a new weapon of mass destruction—only one of them, the remarkable Hungarian physicist Leo Szilard, took that possibility seriously—the discovery of nuclear fission was inevitable. To stop it, you would have had to stop physics. If German scientists hadn’t made the discovery when they did, French, American, Russian, Italian, or Danish scientists would have done so, almost certainly within days or weeks. They were all working at the same cutting edge, trying to understand the strange results of a simple experiment bombarding uranium with neutrons. Here was no Faustian bargain, as movie directors and other naifs still find it intellectually challenging to imagine. Here was no evil machinery that the noble scientists might hide from the problems and the generals. To the contrary, there was a high insight into how the world works, an energetic reaction, older than the earth, that science had finally devised the instruments and arrangements to coart forth. “Make it seem inevitable,” Louis Pasteur used to advise his students when they prepared to write up their discoveries. But it was. To wish that it might have been ignored or suppressed is barbarous. “Knowledge,” Niels Bohr once noted, “is itself the basis for civilization.” You cannot have the one without the other; the one depends upon the other. Nor can you have only benevolent knowledge; the scientific method doesn’t filter for benevolence. Knowledge has consequences, not always intended, not always comfortable, but always welcome. The earth revolves around the sun, not the sun around the earth. “It is a profound and necessary truth,” Robert Oppenheimer would say, “that the deep things in science are not found because they are useful; they are found because it was possible to find them.”
...Bohr proposed once that the goal of science is not universal truth. Rather, he argued, the modest but relentless goal of science is “the gradual removal of prejudices.” The discovery that the earth revolves around the sun has gradually removed the prejudice that the earth is the center of the universe. The discovery of microbes is gradually removing the prejudice that disease is a punishment from God. The discovery of evolution is gradually removing the prejudice that Homo sapiens is a separate and special creation.
On the night of October 12th, the "Sunburst Medallion" was stolen from the highly secured display case in the city museum. The theft occurred sometime between the museum closing at 10:00 PM and the night guard, Mr. Hemant, completing his final round at 1:00 AM. Three primary suspects were identified, all of whom had recently been dismissed from their museum positions: Anjali, the former curator; Bharat, the former security expert; and Chitra, the former exhibits designer.
Here are the established facts and their alibis:
Further investigation revealed that a small, distinctive silver button was found near the display case. Anjali is known to frequently wear a coat with similar unique silver buttons. The security expert, Bharat, had previously boasted that he could remotely disable a certain type of magnetic lock—the same type used on the medallion's case—without needing the code, though the log suggests the code was used.

In a small town lived a close-knit family where every relation could be expressed through simple symbols. For instance, when they said \( A \times B \), it meant \( A \) is the father of \( B \), while \( A \div B \) meant \( A \) is the mother of \( B \). The younger ones were often introduced with \( A + B \), meaning \( A \) was the daughter of \( B \), and the bond of brotherhood was shown by \( A - B \) (A is brother of B).
One day, the children in the family turned these symbols into a playful code. Instead of introducing their parents and siblings in words, they spoke only in symbols. “Look,” giggled little Meena, “\( M + N \div O \)!” Everyone laughed, because they knew it meant Meena was the daughter of \( N \), and \( N \) was the mother of \( O \), making her \( O \)’s sister. What started as a code soon became a family game, making the bonds of father, mother, daughter, and brother not just relations, but symbols of love and togetherness. (165 words)
Four teams – Red (R), Blue (B), Green (G), and Yellow (Y) – are competing in the final four rounds of the Inter-School Science Olympiad, labeled Round A, Round B, Round C, and Round D. Each round consists of one match between two teams, and every team plays exactly two matches. No team plays the same opponent more than once.
The final schedule must adhere to the following rules:

Health insurance plays a vital role in ensuring financial protection and access to quality healthcare. In India, however, the extent and nature of health insurance coverage vary significantly between urban and rural areas. While urban populations often have better access to organized insurance schemes, employer-provided coverage, and awareness about health policies, rural populations face challenges such as limited outreach of insurance schemes, inadequate infrastructure, and lower awareness levels. This urban-rural divide in health insurance coverage highlights the broader issue of healthcare inequality, making it essential to analyze the factors contributing to this gap and explore strategies for more inclusive health protection. A state-level health survey was conducted.
The survey covered 1,80,000 adults across urban and rural areas. Urban residents formed 55% of the sample (that is, 99,000 people) while rural residents made up 45% (that is, 81,000 people). In each area, coverage was classified under four heads – Public schemes, Private insurance, Employer-provided coverage, and Uninsured. In urban areas, Public coverage accounted for 28% of the urban population, Private for 22%, Employer for 18%, and the remaining 32% were Uninsured. In rural areas, where formal coverage is generally lower, Public coverage stood at 35%, Private at 10%, Employer at 8%, while 47% were Uninsured.
For this survey, “Insured” includes everyone covered by Public + Private + Employer schemes, and “Uninsured” indicates those with no coverage at all. Officials noted that public schemes remain the backbone of rural coverage, while employer and private plans are relatively more prevalent in urban centres. (250 words)
