C. that inventors who attempted to create them faced insurmountable technical limitations D. having inspired numerous failed prototypes throughout medieval European history Question 19: A. therefore medieval craftsmen perfected these concepts within several centuries B. and their designs were immediately adopted across Mediterranean cultures C. yet the Industrial Revolution didn't begin until 1,700 years later D. but ancient societies had already mastered complex mechanical engineering Question 20: A. has been why historians ignored such compelling evidence until the recent archaeological findings B. is that these ancient inventors created these remarkable devices without modern tools or scientific knowledge C. would be that modern engineers cannot replicate these designs despite our technological advantages D. was whether ancient societies deliberately concealed their advanced technologies from rival civilizations Question 21: A. although he successfully demonstrated the machine to impressed royal audiences B. meanwhile, similar devices had already been perfected in eastern civilizations C. however, the technology to build it properly didn't exist during his lifetime D. therefore, his contemporaries immediately constructed working prototypes of his design Question 22: A. inventions have surpassed modern technology in efficiency and durability B. whom will discover the complete blueprints in previously unexplored ruins C. had been perfecting for centuries before suddenly disappeared from history D. who continue to study these ancient innovations with great dedication and passion Read the following passage about When Creating Solutions Creates Problems and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30. Imagine creating a solution that becomes your next problem. This paradoxical situation characterizes much of human innovation throughout history. From simple tools to complex machines, these innovations have transformed society. However, many inventions designed to solve one problem often create unexpected new challenges, a phenomenon known as the "invention paradox." This concept challenges our traditional understanding of technological progress and development. The automobile perfectly illustrates this paradox. When cars were first developed, they solved transportation issues, allowing people to travel faster and more comfortably than with horses. They eliminated problems like horse manure in cities and reduced travel time dramatically. Nevertheless, automobiles introduced new problems: air pollution, traffic congestion, and thousands of annual fatalities. The convenience that cars provide comes with significant environmental and social costs that their inventors could not have anticipated or prevented through initial design considerations.
