Beyond restoring lost function, engineers are now exploring implants and prosthetics ① designed to give healthy people abilities beyond ordinary human limits, from night vision to reaction times faster than any athlete could achieve through training alone. Supporters frame this as simply the next step in a long history of human enhancement, no different in principle from eyeglasses or vaccines, only more direct. Critics counter that earlier enhancements ② were broadly available to anyone regardless of wealth, while cutting-edge neural and physical implants are likely ③ remaining expensive for decades, potentially splitting society into those who can afford enhancement and those who cannot. If such a divide hardens, competitive advantages in school, sports, and the workplace could come to depend less on effort than on access to capital. What began as a medical tool for restoring what was lost, in other words, may end up ④ redefining the baseline of what counts as an ordinary human being ⑤ altogether.

Social media researchers use the term context collapse to describe what happens when a single online post reaches audiences that would normally remain ①separate in offline life. In daily interactions, people naturally adjust their tone and content depending on whether they are speaking with family, close friends, or professional colleagues. However, a typical social media feed ②merges these distinct audiences into one undivided crowd, since a single post can simultaneously reach parents, employers, and casual acquaintances. Consequently, users often struggle to decide which version of themselves to present, knowing that a joke suitable for close friends might seem ③professional to a supervisor. This tension forces many users to either ④self-censor heavily or maintain multiple separate accounts tailored to different audiences. Understanding context collapse helps explain why online communication often feels more ⑤complicated.

Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, ① tamper-resistant ledger rather than through a bank or government agency. In theory, this design distributes power away from any single institution and toward the network as a whole. In practice, however, a small number of large players have come to ② dominate many blockchain networks, controlling enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often ③ ample institutional support to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can ④ survive this concentration of power remains one of the technology's most ⑤ unresolved questions.

Air conditioners make summer days more comfortable, but using them ①incorrectly can harm your health. Doctors recommend keeping the difference between indoor and outdoor temperatures ②small, within about five or six degrees. A larger gap forces your body to adjust constantly, which can ③weaken your immune system. This sudden change often leads to headaches and fatigue. To avoid these problems, set your air conditioner to the ④lowest temperature possible, and open a window ⑤regularly to let fresh air in.

Aerobic exercise strengthens the heart by forcing it to pump larger volumes of blood with each beat. Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, meaning it can deliver the same amount of oxygen to working muscles while beating fewer times per minute. This adaptation explains why _______________. Beyond the heart itself, aerobic activity also builds new capillaries within muscle tissue and improves how cells throughout the body respond to insulin.

Color plays a surprisingly powerful role in how consumers perceive brands, often shaping first impressions before a single word is read. Blue, for instance, is frequently used by financial and technology companies because it tends to evoke feelings of trust and stability. Red, in contrast, is associated with energy and urgency, which explains why it appears so often in logos for fast-food chains and clearance sales. Green typically signals freshness or environmental responsibility, making it a popular choice for organic food brands. Despite these general patterns, ___________. Marketers who ignore these cultural differences risk sending unintended messages to international audiences. For this reason, companies expanding into new markets often conduct extensive research before finalizing a logo's color scheme.

As private companies develop the technology to mine asteroids for rare metals and water, a legal question has become urgent: who owns the resources of outer space? Existing international treaties state that no nation may claim sovereignty over celestial bodies, but they say remarkably little about whether a private company may extract and sell what it finds there. Some governments have already passed domestic laws granting their own companies rights to material mined in space, a move that other nations view as _______________.

Every brand has a history, but not every brand knows how to tell it well. (A) For example, a small shoe company once shared the story of its founder's grandfather, who had repaired shoes for workers in need. (B) Consequently, other companies began investing in storytelling as a core part of their marketing strategy. (C) Stories like this create emotional connections that plain advertisements rarely achieve on their own.

Technology has changed the way many jobs are performed today. (A) As a result, workers now need to keep learning new tools throughout their careers. (B) A graphic designer, for instance, must understand digital software that did not exist twenty years ago. (C) Machines and computer programs now handle tasks once done entirely by people.

Job experience programs let students try out real workplaces for a short time. (A) For example, some students spend a day at a hospital, a bakery, or a design studio. (B) In this way, students gain a clearer picture of what each job truly involves. (C) During the visit, they observe workers and sometimes try simple tasks themselves.
