When Mina was a freshman, she often ①spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study ②in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer ③shown better academic performance and self-control years later. Inspired by the study, Mina began ④saving half of her allowance each week instead of spending it all on snacks. After three months, however, she had saved enough to buy a bicycle she had ⑤wanted for over a year.

Setting a goal such as 'I will study harder' rarely leads to ①meaningful improvement. According to psychologists Edwin Locke and Gary Latham, ②specific and challenging goals produce far better performance than vague or easy ones. This idea, known as goal-setting theory, suggests that ③clear targets direct attention and sustain effort over time. To apply this theory effectively, many educators recommend the SMART framework, which requires goals to be Specific, Measurable, Achievable, Relevant, and Time-bound. For instance, a student following this framework might say, 'I will memorize thirty new words every week for two months.' Because the goal includes a clear number and a deadline, progress becomes easy to ④track and evaluate. Challenging goals also tend to increase motivation, since people often work harder when a target feels meaningfully ⑤easy rather than trivially simple.

Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be ①misleading. This practice, known as greenwashing, occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. A company might launch a recycled-packaging line while continuing to pollute rivers through its main factories, creating a false impression of genuine change. Such tactics ②deceive well-intentioned consumers who wish to shop responsibly but lack the tools to ③verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. Therefore, shoppers should look beyond vague labels like green or natural and instead search for ④recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep ⑤declining, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.

Scientists have identified certain gene variants that appear ①less 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. One frequently studied variant, for instance, influences the proportion of slow-twitch versus fast-twitch muscle fibers a person naturally develops, a ratio that ②shapes whether a body leans toward endurance or explosive power. However, researchers caution strongly against interpreting these findings as evidence that athletic greatness is simply ③inherited. Even athletes who carry every favorable variant identified so far still require years of ④disciplined training to translate that genetic potential into actual performance. 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 ⑤determination.

Many students ①assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern called the perfectionism-procrastination cycle. Because perfectionists set impossibly high standards, they often feel ②anxious before they even begin, and the task feels overwhelming. They then ③accelerate the work to avoid facing their own unrealistic expectations, even though delay only increases their stress later. Likewise, an employee facing an important report may check emails repeatedly rather than begin drafting, fearing an early attempt will seem ④inadequate. Ironically, this avoidance guarantees the very failure that perfectionists dread, since ⑤rushed, last-minute work rarely meets their own high standards.

Jian wanted to become a reader for years, but every time he picked up a thick novel, he felt ①overwhelmed and quickly closed it. His cousin, who had read dozens of books that year, told him about something called the two-minute rule. This rule states that a new habit should be shrunk to under two minutes, since a smaller starting point ②strengthens the friction that usually stops people from beginning. Some nights he stopped after that single page, but most nights, once started, he kept reading for twenty or thirty minutes without ③noticing. Because the initial barrier became so small, sitting down no longer felt like a ④burden requiring willpower. Within three months, Jian had finished five books, proving that reducing friction can matter more than ⑤motivation itself.

Have you ever noticed that a ①finished task keeps returning to your mind long after you stopped working? This phenomenon was first noticed by psychologist Bluma Zeigarnik, who saw that waiters remembered ②unpaid orders better than paid ones. Her observation led to what is now called the Zeigarnik effect: people remember ③incomplete tasks more vividly than completed ones. According to this theory, the mind maintains mental tension until a task reaches ④closure, keeping the unfinished task active in memory. Once the task is completed, the tension is ⑤released, and the mind lets go of the details.

When people encounter solid scientific evidence about climate change, we might expect them to accept it without hesitation. However, many individuals still dismiss or downplay such evidence, and psychologists explain this pattern through a concept called motivated reasoning. Motivated reasoning refers to _______________. For example, a person whose livelihood depends on the fossil fuel industry may unconsciously search for reasons to doubt climate data, even while claiming to value scientific accuracy. This happens because accepting uncomfortable facts can threaten a person's sense of self or demand costly lifestyle changes. Therefore, simply presenting more data rarely persuades a committed skeptic. Instead, experts suggest connecting climate information to values the person already holds, such as family safety or economic stability, so that acceptance feels natural rather than threatening.

Not all relationships that people form are equally close or meaningful. (A) Robin Dunbar, an anthropologist, argued that the human brain can only support about one hundred fifty stable relationships at once. (B) Consequently, most of the hundreds of online followers a person accumulates never become genuinely close acquaintances. (C) This cognitive limit applies regardless of how many friends or followers a person collects on social media.

This shift in emphasis reflects a growing understanding of what actually happens inside the body while an athlete is asleep. Coaches have traditionally focused athlete preparation on training volume and nutrition, but a growing body of research suggests that sleep deserves equal attention. ( ① ) During deep sleep, the body releases growth hormone, a substance essential for repairing muscle tissue damaged during intense training, while the brain consolidates motor skills practiced earlier that day into more stable, efficient patterns. ( ② ) Athletes who sleep fewer than seven hours a night have been shown to suffer more injuries, slower reaction times, and reduced accuracy compared to well-rested peers performing the identical drills. ( ③ ) Frequent travel across time zones compounds 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. ( ④ ) In response, many professional teams now employ sleep specialists who design travel schedules, control bedroom lighting and temperature, and even adjust competition start times when possible.
