VO2 max, ① defined as the maximum volume of oxygen a person's body can consume and use during intense exercise, is widely regarded as one of the best single indicators of cardiorespiratory fitness. Elite endurance athletes typically post VO2 max values far higher than those of untrained individuals, ② reflecting hearts that pump larger volumes of blood and muscles that extract oxygen from that blood with remarkable efficiency. While genetics accounts for a substantial portion of an individual's potential VO2 max, consistent aerobic training can still ③ raise the measurement considerably over months of dedicated effort. Interval training, which alternates short bursts of near-maximal effort with periods of recovery, has proven particularly effective at ④ improve this measurement compared to steady, moderate-intensity exercise alone. It is worth noting, however, that a high VO2 max does not guarantee success in competition, since factors such as running economy, pacing strategy, and mental resilience also ⑤ play a decisive role in determining who actually crosses the finish line first.

Among strategies for improving concentration, the Pomodoro Technique remains one of the most widely ①recommended methods for students and workers. This technique involves working with full attention for twenty-five minutes, then ②taking a short five-minute break before starting the next session. After completing four of these cycles, a longer break of fifteen to thirty minutes ③is usually taken to allow mental recovery. The method assumes that sustained focus becomes harder to maintain as time passes, so frequent short breaks prevent mental fatigue from ④build up. Students preparing for exams report finishing reading assignments faster when they follow this structured rhythm instead of studying without interruption. Office workers find that dividing large projects into short, timed intervals makes overwhelming tasks feel more manageable. Because each interval has a clear start and end, procrastination becomes less tempting, since beginning a single twenty-five-minute session requires less commitment ⑤than beginning an entire project.

The twenty-hour rule proposes that years of practice ①are not needed to become skilled at a new activity. Only about twenty hours of effort are needed to reach a useful level. Unlike theories ②claiming true mastery requires ten thousand hours, this rule targets a more modest goal. According to supporters, practicing any new skill produces the fastest visible improvement, since a beginner ③has room to grow. Someone learning guitar can typically strum simple chords and follow a basic song within twenty hours of ④daily practice. Advocates emphasize that the twenty hours must be deliberate and focused, broken into short daily sessions rather than one long stretch, and ⑤aims at fixing weaknesses rather than repeating what one already knows.

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.

Anthropologist Robin Dunbar ①proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, ②which restricts how many meaningful connections a person can cognitively manage. In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far ③exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships ④are close or emotionally supportive. Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain ⑤largely unnoticing.

Goal-setting theory has influenced not only classrooms but also workplaces around the world. (A) Many companies now train managers to set specific quarterly targets rather than simply asking employees to 'do their best.' (B) As a result, employees often report clearer priorities and a stronger sense of accomplishment. (C) These targets typically include measurable numbers, such as sales figures or project deadlines.

Many self-help books emphasize the cue-routine-reward loop as a tool for building better habits. (A) For example, athletes who want to build a stretching habit often rely on a specific cue, such as arriving at the gym, to trigger the same short routine every time. (B) Over time, this consistent pairing strengthens the neural pathway connecting the cue to the routine, making the behavior feel almost automatic. (C) According to this model, every habit consists of three connected parts: a cue that triggers behavior, a routine that follows, and a reward that reinforces it.

주어진 문장: Yet this idea sounds strange to most people, who assume that close relationships would naturally provide better opportunities than distant ones. Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. ( ① ) According to this theory, people who see each other only occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. ( ② ) This happens because strong ties tend to share the same social circles and, therefore, already possess similar knowledge. ( ③ ) Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. ( ④ ) For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. ( ⑤ ) Social media platforms have made maintaining such connections remarkably easier, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings.

주어진 문장: This is why productivity coaches often recommend starting with just one or two blocks per day rather than filling the entire schedule at once. Time blocking is a time-management technique in which a person divides the day into fixed blocks. Each block is then assigned to a single task. ( ① ) Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. ( ② ) This approach lowers the mental effort of deciding what to do next, since the schedule already provides the answer. ( ③ ) It also limits multitasking, because each block is reserved for only one activity at a time. ( ④ ) For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing, while another student may reserve an evening block solely for vocabulary review. Because each block has a clear boundary, unfinished work is less likely to quietly spread into the next task. Many people who adopt time blocking feel more organized throughout the day. ( ⑤ )

주어진 문장: She was surprised at how little willpower this required once the routine became familiar. Minji had tried for years to build a bedtime reading habit but always forgot once under the blanket. ( ① ) During summer, she found a method called habit stacking. It means attaching a new habit to an existing one so it acts as a reminder. ( ② ) Her existing habit was brushing her teeth every night, so she decided to place her book beside her toothbrush. ( ③ ) After brushing her teeth, she would pick up the book, letting one action trigger the next. ( ④ ) Within two weeks, opening the book after brushing felt almost automatic, requiring no conscious effort. ( ⑤ ) Encouraged by this success, Minji stacked another habit onto her morning routine, reviewing vocabulary words after making her bed.
