A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that converts a biological reaction into a signal a computer can ① read. When the target molecule, whether glucose in blood or a trace of a pathogen, binds to the biological component, it triggers a ② massive measurable change that the device translates into a readable number. This design has already transformed diabetes management, letting patients monitor blood sugar ③ continuously through a small sensor worn under the skin rather than pricking a finger several times a day. Engineers are now racing to extend the same principle to detect subtler targets, from cancer cells circulating in the bloodstream to trace ④ contaminants in drinking water. The central challenge is not detecting the target but doing so reliably outside a controlled laboratory, since a sensor that performs well on a clean lab bench can behave ⑤ erratically once exposed to a real body or a real river.

When people estimate the value of an unfamiliar product, they rarely rely on objective calculation alone; instead, they anchor their judgment to whatever numerical reference happens to be presented first, however ①arbitrary that number may be. This phenomenon exerts a ②disproportionate influence on price perception precisely because initial figures function as a kind of cognitive gravity that subsequent estimates struggle to escape. A shopper who first sees a jacket listed at $300 before it is marked down to $150 will likely judge the discounted price as an excellent ③bargain, regardless of whether $150 actually reflects the jacket's true worth. Retailers, well aware of this bias, frequently display a ④deflated "original price" beside a discounted one, not because the higher figure is meaningful, but because it recalibrates customers' expectations. Even professionals are not immune: negotiators who open with an extreme initial offer often secure more ⑤favorable final terms than those who begin with a moderate one.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. During recent years, this gap became ① impossible to ignore, as families in rural areas or low-income neighborhoods struggled to complete schoolwork that assumed a stable connection and a personal device. Some policymakers initially treated internet access as a ② convenience, comparable to cable television, rather than as infrastructure essential to modern life. That assumption is increasingly being reconsidered, particularly as more essential services move online by default. Closing this divide will require ③ far less than simply distributing devices; it will demand ④ sustained investment in the physical networks that carry information into every home, ⑤ regardless of income or location.

Last month, I attended a three-day career camp during summer vacation. On the first day, I chose the broadcasting workshop, where students practiced writing short news scripts and reading them in front of a camera. It was harder than I expected, since staying calm while a camera recorded my every move felt strange at first. By the second day, however, I began to enjoy the challenge, and my confidence grew with each attempt. The instructors, who all had real broadcasting experience, gave ___________ rather than simple praise, which helped us improve quickly.

City governments increasingly market dense networks of surveillance cameras as a safety upgrade. Yet the same infrastructure that catches criminals also creates a permanent record of where ordinary citizens go about their daily lives. Once a camera network exists, its purpose can quietly expand, often without new public debate. Civil liberties groups argue that _______________.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. During an internship, he helped design a small satellite intended to monitor crop health from orbit, a project that combined engineering with agricultural science. He realized that ___________. After graduation, Daniel joined a startup developing lunar landing equipment, a job that barely existed when he first imagined his future career.

Food poisoning becomes much more common in summer, so it is important to handle food carefully. (A) In addition, keep perishable food in the refrigerator and never leave it out at room temperature for long. (B) First, always wash your hands with soap before you prepare or eat any food. (C) Finally, if you notice symptoms such as stomach pain or vomiting, see a doctor as soon as possible.

주어진 문장: This is because the brain naturally pays more attention to things that are connected to a person's goals. Many students who reach their goals share one habit: they picture the goal clearly before they even start working. ( ① ) This process, called visualization, means imagining a goal in detail, often by drawing pictures or writing specific descriptions. ( ② ) For example, a student who dreams of studying abroad might make a board filled with photos of a foreign campus and a list of steps to get there. ( ③ ) Seeing these images every day keeps the goal fresh in mind and reminds the student why the effort matters. ( ④ ) Visualization also helps people notice small opportunities they might otherwise miss. ( ⑤ ) In addition, picturing success in advance can lower anxiety, because the mind grows familiar with the process instead of fearing an unknown outcome.

Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often no institution left to appeal to. 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, tamper-resistant ledger. ( ① ) In theory, this design distributes power away from any single institution and toward the network as a whole. ( ② ) In practice, however, a small number of large players have come to dominate many blockchain networks. ( ③ ) They control enough computing power or currency to influence outcomes that were supposed to be decided collectively. ( ④ ) Whether decentralization can survive this concentration of power remains one of the technology's most unresolved questions. ( ⑤ )

Fairness, in other words, is not a feature that can simply be patched in once a problem is discovered. Many large companies now rely on artificial intelligence to screen job applications before a human ever sees them. ( ① ) These systems promise efficiency, scanning thousands of resumes in seconds and ranking candidates according to patterns drawn from previous hiring decisions. ( ② ) However, this reliance on historical data creates a troubling risk. ( ③ ) If a company's past hiring favored a particular group, the algorithm may learn to treat that pattern as a marker of success and quietly reproduce it, even when no one intended discrimination. ( ④ ) Unlike a human interviewer, the system offers no explanation for its choices, which makes the bias difficult to detect until an outside audit reveals it. ( ⑤ ) Some researchers argue that fairness cannot be added afterward; it must be built into the system's design from the very beginning.
