A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that ①convert a biological reaction into a signal a computer can read. When the target molecule, whether glucose in blood or a trace of a pathogen, ②binds to the biological component, it triggers a small measurable change that the device translates into a readable number. This design has already transformed diabetes management, ③letting patients monitor blood sugar 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 ④to detect subtler targets, from cancer cells circulating in the bloodstream to trace 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 erratically once ⑤exposed to a real body or a real river.

For a class project, I ①interviewed a local architect who has worked in the field for over fifteen years. She said she had always loved ②drawing buildings as a child. She explained that architects must balance creativity with practical concerns like safety and cost. When I asked about challenges, she mentioned that clients sometimes ③changes their minds after a design is finished. She also advised students ④to visit construction sites whenever possible, since seeing a real building take shape teaches lessons no classroom can offer. At the end of the interview, she smiled and said that choosing architecture ⑤was the best decision she had ever made.

Advertisements often rely on subtle psychological techniques that persuade viewers without their conscious awareness. One common method, known as social proof, shows images of many people using or enjoying a product, suggesting that its popularity guarantees quality. Another technique appeals to authority, featuring experts or professionals endorsing a product to make it seem more credible and trustworthy.

Repetition also plays a significant role, since seeing the same advertisement multiple times increases familiarity, which people often mistake for reliability. Researchers studying consumer behavior have found that ___________, since awareness disrupts the automatic psychological response advertisers depend on.

Before making a purchase, most online shoppers now read reviews written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often seem more trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs have become a serious problem, undermining consumer trust. Platforms that fail to detect these fraudulent posts risk losing credibility with their users, who expect authentic opinions when making decisions. To address this issue, several review platforms have begun using artificial intelligence to identify suspicious patterns. Ultimately, the power of online reviews ___________.

Last week, I started feeling tired and had a mild headache every afternoon at school. At first, I thought I was just stressed about exams, but my mother told me it might be air-conditioning sickness, which happens when ___________. After doing some research, I learned a few simple ways to prevent it, such as wearing a light jacket indoors, drinking warm water, and stretching every hour.

Strong summer sunlight can seriously damage your skin if you are not careful, because ___________. To protect your skin, apply sunscreen with a high SPF before going outside, and reapply it every two hours. Wearing a hat and sunglasses also helps shield your face and eyes from direct sunlight.

Every day, we leave behind marks of the gases that warm our planet, much like footprints left in wet sand. These marks, often called our carbon footprint, come from small choices such as driving, eating, and using electricity. (A) For example, turning off lights when leaving a room reduces the energy that power plants must produce. Walking or biking to school instead of riding in a car also lowers the amount of gas released into the air. (B) In contrast, leaving devices plugged in all night quietly increases our footprint without our notice. Therefore, students who practice these simple habits regularly can shrink their footprint significantly. Small daily choices, repeated over time, become powerful tools for protecting the environment we all share. (C) Many students think that only large factories create these marks, but ordinary habits at home also matter greatly.

Storing summer fruit properly can help you avoid waste and enjoy fresher flavors. (A) Berries, however, should not be washed until just before eating, because moisture encourages mold to grow. (B) Watermelon and melon should be kept in the refrigerator once they are cut, since warm air speeds up spoiling. (C) Bananas, unlike most fruit, are best kept on the counter rather than in the refrigerator.

Sales events are far more psychologically calculated than they first appear. (A) A crossed-out original price, for instance, makes the discounted price seem like an exceptional deal, regardless of whether it truly is one. (B) Retailers rely on specific visual and verbal cues to make shoppers feel they are getting exceptional value. (C) Combined with phrases suggesting limited availability, these cues push customers toward faster, less deliberate purchasing decisions.

주어진 문장: Many people, once they realize how much unused subscriptions cost them, feel genuine regret.

( ③ ) However, some critics argue that subscriptions encourage people to pay for services they barely use, quietly draining their monthly budgets. ( ④ ) Because canceling often requires several steps, many consumers simply forget to end subscriptions they no longer need. ( ⑤ ) Consequently, experts recommend reviewing subscription lists regularly to avoid unnecessary expenses.
