More and more teenagers today ①dream of starting their own business someday. Some students design and sell handmade jewelry online, while others ②create simple mobile apps as a hobby. This growing interest is partly due to the internet, ③which make it easy to reach customers without a physical store. Starting a small business also teaches skills ④that traditional classes rarely offer, such as managing money and marketing a product. Still, most teen entrepreneurs say that failure ⑤taught them more than any success did.

Drinking enough water ①are especially important during the hot summer months. When you sweat a lot, your body loses not only water but also important minerals ②called electrolytes. If you do not replace these losses, you may feel tired, dizzy, or ③even suffer from muscle cramps. It is best ④to avoid sugary drinks and too much caffeine, since they can make dehydration worse. Eating water-rich fruits and vegetables ⑤can also help you stay hydrated.

Blockchain technology was originally promoted as a way ① to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger rather than through a bank or government agency. In theory, this design ② 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 dominate many blockchain networks, ③ controlled enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, there is often no institution left ④ to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can survive this concentration of power ⑤ remains one of the technology's most unresolved questions.

Within days, thousands of people began recreating the dance and tagging the brand, turning an ordinary product launch into a ①viral trend. Because participants created the content themselves, viewers found the videos far more ②entertaining than a traditional advertisement would have been. The company barely spent any money on production, yet the challenge reached ③millions of viewers across multiple platforms. Encouraged by this success, other brands quickly attempted similar challenges, though many ④succeeded in generating the same excitement. Researchers later explained that the original challenge succeeded because it felt spontaneous and fun rather than obviously ⑤commercial.

Social media researchers use the term context collapse to describe what happens when a single online post reaches audiences that would normally remain separate 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 merges 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 unprofessional to a supervisor. For example, a party photo posted for friends could later damage someone's reputation if an employer notices it. This tension forces many users to either self-censor heavily or maintain multiple separate accounts tailored to different audiences. Understanding context collapse _______________.

Every time a smartphone connects to a network, it records a data point that can later map where its owner has been. The real danger emerges when location data from multiple sources is combined. Companies often argue that anonymized data cannot be traced back to individuals, yet researchers have repeatedly shown that _______________. As a result, privacy experts increasingly insist that location data deserves the same legal protection as medical records.

However, even confident swimmers can get into trouble in open water. Summer is the best time to enjoy swimming pools, rivers, and beaches with family and friends. ( ① ) First, always swim in areas that are supervised by a lifeguard, and never swim alone, even if you are a strong swimmer. ( ② ) It is also important to check the weather and water conditions before entering the water, since strong currents and sudden storms can appear without warning. ( ③ ) Wearing a life jacket in open water is essential, especially for children and beginners. ( ④ ) Taking regular breaks during long swims helps prevent exhaustion. ( ⑤ ) Learning basic rescue skills is another good habit that could help you save a life someday.

I thought for a moment before answering that designing posters for school events always felt exciting. Yesterday, I visited my school's career counselor because I felt confused about my future. ( ① ) I told her that I enjoyed both science and art, but I could not decide which subject to pursue. ( ② ) She listened carefully and then asked me a simple question: what activities make me lose track of time? ( ③ ) She smiled and said that this kind of clue often reveals a genuine interest, more than any test score can. ( ④ ) She suggested that I try combining my two interests by exploring careers such as scientific illustration or product design. ( ⑤ ) Our short conversation gave me a clearer sense of direction than weeks of worrying alone had.

This is a decision, in short, that no single person should be allowed to make alone. The discovery of CRISPR gene-editing technology gave scientists a tool precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. ( ① ) Yet the same precision that makes CRISPR so promising also makes it dangerous in the wrong hands. ( ② ) Editing a gene in a sperm, egg, or early embryo does not simply change one patient. ( ③ ) It alters the genetic code passed down to every future generation. ( ④ ) Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. ( ⑤ ) Critics worry, however, that this line will become harder to enforce than it is to draw.

Similar changes are taking place in other fields as well. As technology develops rapidly, many new jobs are appearing that did not exist a decade ago. ( ① ) Data analysts, for example, help companies make decisions based on huge amounts of information. ( ② ) Renewable energy technicians install and repair solar panels and wind turbines, meeting the growing demand for clean power. ( ③ ) These emerging jobs share one common feature: they combine technical skill with the ability to solve real-world problems. ( ④ ) Experts predict that future workers will need to keep learning new skills throughout their careers, since technology continues to change so quickly. ( ⑤ ) For students planning their future, staying curious and adaptable may matter more than a single fixed career path.
