A flexitarian is someone who mainly ①eating plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock ②produces a significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at ③trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it ④allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, ⑤believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

Time-management researchers frequently mention a principle ①known as Parkinson's Law, which states that work expands to fill the time available for its completion. According to this idea, a task that could be finished in one hour will often stretch to fill an entire afternoon if that much time ②is scheduled for it. Students who set vague deadlines frequently experience this effect, spending extra hours ③refined a report that was already complete. Employees given a full week for a simple project may also delay meaningful progress until the final days, even though the actual work ④requires far less effort. This pattern happens partly because people unconsciously adjust their pace to match perceived urgency. Setting shorter, more specific deadlines can counter this tendency, forcing tasks to fit within a tighter and more realistic window. By recognizing how flexible time encourages unnecessary delay, individuals can complete assignments more efficiently ⑤without sacrificing quality.

Athletes preparing for major endurance events sometimes ① trains for weeks at high altitude, where the air contains less oxygen than at sea level, in hopes of gaining a physiological edge once they return to compete at lower elevations. In this thin air, the body responds by producing more red blood cells, ② which carry oxygen more efficiently through the bloodstream to working muscles. When these athletes return to sea level, where oxygen is more abundant, their blood ③ retains this elevated capacity for a limited period, potentially translating into improved endurance performance. However, the benefits of altitude training are far from guaranteed, since individual athletes respond quite differently to the same conditions, and some experience excessive fatigue that ④ undermines the very training they hoped to complete. Many elite programs therefore follow a strategy known as live high, train low, in which athletes sleep at altitude to stimulate blood adaptations but perform intense workouts at lower elevation ⑤ to maintain quality and intensity.

Planning a multi-city trip once meant hours ① spent comparing flight schedules, reading hotel reviews, and mapping out which sights were close enough to visit in a single day. AI travel planners now compress much of that work into a short conversation, ② asking about a budget, a travel style, and a handful of preferences before generating a full day-by-day itinerary within minutes. The tool draws on enormous amounts of data, including flight prices, seasonal weather patterns, and reviews ③ leaving by previous travelers, to suggest a route that avoids obvious scheduling conflicts. Many travelers appreciate ④ having a solid starting point rather than a blank page. Still, seasoned travelers warn that these itineraries can feel oddly generic, often ⑤ steering users toward the same popular landmarks.

Many companies today advertise their products as environmentally friendly, yet not all of these claims are accurate. This practice, ①knowing as greenwashing, involves exaggerating or fabricating a product's positive impact on the environment. Consumers, ②who are increasingly concerned about climate change, often trust such claims without questioning them closely. As a result, they may pay higher prices for products ③that are no more sustainable than ordinary alternatives. Genuine environmental efforts, which usually ④require significant investment and long-term planning, are far more costly than simply changing a label. Therefore, governments should establish clear standards ⑤that require companies to prove their environmental claims with verifiable data.

주어진 문장: The financial and reputational damage caused by a single attack can be enormous. As more businesses move their operations online, cyberattacks have become one of the most serious threats facing modern companies. ( ① ) Hackers now target everything from small retail websites to massive financial institutions, stealing sensitive data or demanding ransom payments. ( ② ) In response, demand for cybersecurity professionals has surged across nearly every industry. ( ③ ) These specialists design systems that detect suspicious activity, patch vulnerabilities before criminals can exploit them, and train employees to recognize phishing attempts. ( ④ ) Universities have responded by creating specialized degree programs, while many companies now offer scholarships to attract students into this growing field. ( ⑤ ) Despite this expansion, experts estimate that millions of cybersecurity positions worldwide remain unfilled.

The convenience comes at a cost that few passengers consider, however. A navigation app calculating a route rarely relies on distance alone; instead, it constantly weighs real-time traffic reports, past congestion patterns for that time of day, and even data from other drivers' phones currently on the road. ( ① ) This flood of information allows the app to reroute a driver away from a sudden accident within seconds, often before the driver has any idea the accident occurred at all. ( ② ) When thousands of drivers are simultaneously redirected onto the same shortcut, that quiet side street can quickly become as congested as the highway it was meant to help travelers avoid. ( ③ ) Residents of these once-quiet neighborhoods have increasingly complained about the sudden surge of unfamiliar traffic. ( ④ ) They argue that an algorithm optimizing for individual convenience can end up creating a new, entirely different problem for the wider community. ( ⑤ )

Genetic potential, in other words, is merely a starting point, never a finished product. Scientists have identified certain gene variants that appear more frequently among elite endurance athletes than among the general population, along with a separate set that seems to favor explosive, power-based sports such as sprinting. ( ① ) One frequently studied variant, for instance, influences the proportion of slow-twitch versus fast-twitch muscle fibers a person naturally develops, a ratio that shapes whether a body leans toward endurance or explosive power. ( ② ) However, researchers caution strongly against interpreting these findings as evidence that athletic greatness is simply inherited. ( ③ ) Even athletes who carry every favorable variant identified so far still require years of disciplined training to translate that genetic potential into actual performance, and many elite competitors lack some of these supposedly advantageous variants altogether. ( ④ ) Genetics may set a rough ceiling on an individual's ultimate potential, but where any particular athlete lands within that range depends overwhelmingly on training quality, nutrition, coaching, and sheer determination. ( ⑤ )

주어진 문장: This fear of missing out, often shortened to FOMO, drives many shoppers to act faster than they normally would. Limited-edition products are goods that are released in small quantities for a short period of time. ( ① ) Many companies use this strategy because scarcity naturally increases how much people desire an item. ( ② ) When consumers believe that a product will disappear soon, they often feel pressured to buy it immediately rather than wait. ( ③ ) For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight. ( ④ ) However, this psychological pressure can lead to purchases that are driven by fear rather than genuine need. ( ⑤ ) As a result, some shoppers later regret spending money on products they rarely use afterward.

주어진 문장: Without such improvements, even the most generous rewards program cannot compensate for a disappointing product. Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers tend to spend more and recommend products to others. ( ① ) Companies invest significant resources in loyalty programs, offering points, discounts, and exclusive access to encourage repeat purchases. ( ② ) However, some critics argue that these programs manipulate consumers into staying with a brand out of habit rather than genuine satisfaction. ( ③ ) Genuine loyalty, they contend, should be earned through consistent quality and honest treatment of customers. ( ④ ) Furthermore, excessive focus on retaining existing customers can cause companies to neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. ( ⑤ ) As markets become more competitive, relying solely on loyalty programs without addressing underlying product quality may ultimately backfire.
