Many people believe that building a new habit requires strong willpower or motivation. However, psychologist BJ Fogg argues that habits form more ①easily when a behavior itself becomes simple to perform. His theory, called the Fogg Behavior Model, states that a behavior happens only when motivation, ability, and a prompt occur together. When motivation is ②low, the model suggests, the task must be made extremely ③difficult, or it will not happen at all. For instance, a person who wants to exercise daily succeeds more often by committing to one push-up than to a long workout. Fogg calls this idea the law of ④least effort, since people naturally choose the option requiring the least energy. A student who wants to read more might leave a book open on the desk rather than setting a vague goal. By lowering the required effort, people reduce the ability barrier and make steady action far more ⑤achievable.

Many people struggling to fall asleep in noisy environments turn to white noise machines, devices that emit a ① chaotic, uniform sound covering a broad range of frequencies. The appeal lies in a phenomenon called auditory masking, in which a constant background sound makes sudden noises, such as a slamming door, ② less noticeable to the sleeping brain. Without this masking effect, an abrupt change in sound is far more likely to trigger a brief awakening, even if the sleeper does not ③ consciously remember it the next morning. Studies comparing sleep in quiet rooms with sleep alongside white noise have found that participants using white noise experienced fewer of these brief awakenings and reported feeling more ④ rested. However, researchers caution that the benefit depends heavily on volume and consistency, since noise that is too loud or that varies unpredictably can itself become a source of ⑤ disruption rather than a remedy.

Coaches have traditionally focused athlete preparation on training volume and nutrition, but a growing body of research suggests that sleep deserves ① equal attention. During deep sleep, the body releases growth hormone, a substance essential for repairing muscle tissue damaged during intense training, while the brain ② consolidates motor skills practiced earlier that day into more stable, efficient patterns. Athletes who sleep fewer than seven hours a night have been shown to suffer ③ more injuries, slower reaction times, and reduced accuracy compared to well-rested peers performing the identical drills. Frequent travel across time zones ④ simplifies this challenge considerably, since jet lag can disrupt an athlete's natural sleep-wake cycle for several days after a long flight, sometimes right before an important competition. In response, many professional teams now employ sleep specialists who design travel schedules, control bedroom lighting and temperature, treating sleep as an ⑤ active and measurable component of overall athletic training.

After a strenuous workout, muscle fibers experience thousands of ① microscopic tears, and the body immediately begins a repair process that ultimately makes the muscle stronger than it was before. This repair depends heavily on amino acids, the building blocks that protein supplies, which is why sports scientists recommend consuming protein within a couple of hours after training. Waiting too long to eat can ② slow recovery, since a muscle's sensitivity to amino acids gradually declines once that window closes. Many athletes assume that eating an enormous quantity of protein in a single sitting will ③ delay this process, but the body can only use a limited amount at once; the rest is simply burned for energy or stored as fat. For this reason, nutritionists generally advise spreading moderate portions of protein ④ evenly across several meals throughout the day rather than saving it all for one large post-workout ⑤ meal.

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 ①trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly ②more 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, ③undermining consumer trust. Platforms that fail to detect these fraudulent posts risk ④gaining credibility with their users, who expect authentic opinions when making decisions. Ultimately, the power of online reviews depends entirely on their perceived ⑤honesty.

When a beverage company launched a new flavor last summer, the marketing team faced a tight budget and needed a creative solution. Instead of relying on expensive television commercials, they designed a simple dance challenge and invited a handful of everyday users to post videos using the product. Within days, thousands of people began recreating the dance and tagging the brand, turning an ordinary product launch into a viral trend. The company barely spent any money on production, yet the challenge reached millions of viewers across multiple platforms. Encouraged by this success, other brands quickly attempted similar challenges, though many failed to generate the same excitement. Researchers later explained that the original challenge succeeded because it felt spontaneous and fun rather than obviously commercial. This case demonstrates that ___________.

Influencer marketing has become one of the most powerful tools that companies use to reach young consumers. Unlike traditional advertisements, which often feel distant and impersonal, posts created by influencers seem more like advice from a trusted friend. This sense of closeness, built through years of sharing daily life online, makes followers more willing to trust product recommendations than ordinary commercials. For example, a skincare brand promoted by a popular lifestyle influencer can sell out within hours simply because her audience believes her opinions are honest. However, this trust can be exploited when influencers promote products they have never actually tried. As a result, several countries now require influencers to clearly disclose paid partnerships before posting sponsored content. Consumers are becoming more cautious, checking whether reviews are sponsored before making a purchase. In the end, influencer marketing ___________.

After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. (A) The system is not without drawbacks, however, since favoring titles similar to what a viewer already enjoys can quietly narrow someone's exposure to unfamiliar genres, directors, or cultures. (B) Instead, a recommendation algorithm compares that viewer's habits with patterns drawn from millions of other users, then ranks thousands of titles in order of predicted interest. (C) This approach keeps viewers engaged far longer than a simple list of new releases ever could, which is precisely why streaming companies invest so heavily in refining it.

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.

In short, an effective fueling plan treats carbohydrate loading as one tool among many, not a substitute for well-rounded nutrition. In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. ( ① ) The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. ( ② ) Because glycogen serves as the primary fuel source during prolonged, intense exercise, entering an event with fuller stores can delay the point of exhaustion that runners often call hitting the wall. ( ③ ) Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort. Athletes are therefore advised to practice their nutrition strategy during training rather than experimenting with it for the first time on race day. ( ④ ) Beyond carbohydrates, adequate protein and micronutrient intake throughout the training cycle remains essential, since fueling strategy is only one part of a much larger nutritional picture.
