In the last century, the pursuit of technological innovation has profoundly reshaped human society. While many celebrate the proliferation of digital devices, artificial intelligence, and biotechnology, some scholars warn of a paradox: progress can also generate unforeseen vulnerabilities. For instance, the rapid spread of smartphones has revolutionized communication, enabling instant connectivity across continents. Yet, it has simultaneously fostered social isolation, cybercrime, and the erosion of privacy. Similarly, breakthroughs in genetic engineering promise cures for hereditary diseases but also ignite ethical controversies about “designer babies” and genetic inequality.

Another area of contention is automation. Factories once filled with workers have increasingly been replaced by machines capable of performing repetitive tasks more efficiently and cheaply. Proponents argue this leads to greater productivity and lower consumer costs. Critics, however, highlight the displacement of workers and the widening gap between those who possess technological expertise and those left behind. This economic polarization is not merely theoretical. It is visible in many industrialized nations today, where urban centers thrive while rural communities languish.

Ultimately, the question is not whether innovation is desirable, but how it should be managed. A purely profit-driven approach risks undermining human dignity and social stability. Conversely, carefully crafted policies, such as retraining programs and digital literacy initiatives, could ensure that technological progress becomes a catalyst for inclusive growth rather than division. The trajectory of the future depends less on the speed of innovation than on the wisdom with which society chooses to direct it.

Câu 16 What is described as a paradox of technological progress?

Questions 23-30: Read the passage carefully.

Throughout history, rivers have been lifelines of civilization, providing water, fertile soil, and avenues of trade. The Amazon River, however, stands out not merely for its size but for the ecological complexity it sustains. Stretching across South America, it nourishes the largest tropical rainforest on Earth-a biome that regulates global climate and houses unparalleled biodiversity. From jaguars prowling its banks to microscopic fungi decomposing organic matter, the Amazon is a web of interdependence.

Yet, this delicate equilibrium is under mounting pressure. Deforestation, often driven by cattle ranching and soybean cultivation, has stripped vast tracts of forest, releasing carbon into the atmosphere and diminishing the forest’s role as a “carbon sink.” Furthermore, large-scale dam projects disrupt natural water flow, imperiling aquatic species and indigenous communities whose livelihoods depend on seasonal flooding cycles. Climate change exacerbates these threats, intensifying droughts and wildfires that further degrade the ecosystem.

Conservationists argue that protecting the Amazon is not solely a regional responsibility but a global imperative. Its destruction would accelerate climate instability, affect rainfall patterns far beyond South America, and cause irreversible species loss. On the other hand, political leaders in some nations contend that economic development cannot be subordinated entirely to environmental concerns. They argue that impoverished populations need jobs and infrastructure, which large-scale industries can provide.

Navigating this conflict requires nuanced strategies: incentivizing sustainable agriculture, strengthening indigenous land rights, and fostering international cooperation. Without such measures, the Amazon’s future and by extension, humanity’s remains perilously uncertain.
