Psychologist Leon Festinger introduced social comparison theory, which ①explains that people evaluate their own abilities and opinions by comparing themselves with others. According to this theory, individuals engage in upward comparison when they measure themselves against someone ②who appears more successful, attractive, or accomplished. Social media platforms, filled with carefully edited photos and exaggerated achievements, ③provide endless opportunities for this kind of comparison. For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life ④are somehow inadequate. Unlike comparing oneself with someone in a similar position, which can sometimes boost confidence, upward comparison frequently ⑤triggers envy, dissatisfaction, and lower self-esteem.

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.

When the body fights off an infection, the immune system relies heavily on adequate sleep to function ①effectively. During deep sleep, the body produces and releases cytokines, proteins that help ②regulate immune responses and coordinate the fight against harmful invaders. People who consistently sleep fewer than six hours a night show measurably ③weaker antibody responses after vaccination compared with those who sleep seven or eight hours. Chronic sleep deprivation also appears to ④reduce low-grade inflammation throughout the body, a state that has been linked to a higher risk of heart disease. Rather than being a passive state, sleep functions as an active period during which the immune system repairs itself and ⑤prepares for future threats.

The rise of autonomous vehicles has created both excitement and anxiety within the transportation industry. (A) In particular, long-distance trucking jobs are expected to shrink significantly as autonomous trucks become more common on highways. (B) At the same time, entirely new positions are emerging, such as remote operators who monitor fleets of self-driving vehicles from control centers. (C) On one hand, many professional drivers fear that automation will eliminate the jobs they currently depend on.

Many students struggle not with lack of effort but with lack of structure when studying for exams. (A) Once colors are assigned, the student blocks specific hours of the day for each subject, following the same order as a printed timetable. (B) As a result, switching between subjects no longer feels confusing, because each color block signals exactly what should happen next. (C) One student solved this problem by giving each subject a distinct color on a printed weekly calendar before the semester began.

As the job market continues to change, experts have identified several core competencies that will matter most in the future. (A) Beyond such technical knowledge, however, employers increasingly value problem-solving and adaptability when evaluating candidates. (B) Technical literacy, including basic coding and data analysis, has become nearly as fundamental as reading and writing once were. (C) Communication skills matter as well, since many future jobs will require collaborating with both human colleagues and intelligent systems.

Habit researchers often note that people overestimate the role of motivation in daily routines. (A) As a result, they frequently give up soon after starting, blaming themselves for lacking discipline. (B) In contrast, Fogg's framework suggests that shrinking the task itself is more effective than boosting motivation. (C) Because motivation naturally rises and falls, relying on it alone often leads to inconsistent effort.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. (A) Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. (B) When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and the resulting impairment in attention and mood can resemble that of a person who has been awake for an entire night. (C) Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. (A) The discomfort arises because the body's internal clock, which governs sleep, hunger, and alertness, continues to run on the schedule of the departure city even after landing, and realigning it typically takes about one day for every time zone crossed. (B) Flying eastward tends to produce more severe symptoms than flying westward, because advancing the internal clock forward is generally harder for the body than delaying it. (C) Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself.

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.
