The planning fallacy describes the tendency to ①systematically underestimate how long a task will take, even when experience suggests otherwise. Psychologists ②who studied this bias found that people focus mainly on an idealized, best-case version of a project. They focus less on how similar projects actually unfolded before. A student who insists an essay takes two hours, despite ③needing five hours for every previous essay, shows a clear instance of the fallacy. Large construction projects offer another example. Officials frequently predict completion dates that later ④proves far too optimistic once delays appear. Some researchers recommend a technique called reference class forecasting, ⑤comparing a new task to similar completed tasks.

Minjun used to leave half of his lunch tray full of ①untouching rice and vegetables every day. Last spring, his class started a campaign ②called "Clean Plate Day" to reduce food waste. However, his teacher explained that leftover food thrown away every day ③adds up to a huge amount of waste. She compared uneaten food to money ④dropped carelessly on the street, which nobody bothers to pick up. He decided to take only what he could finish and ⑤to try new vegetables slowly.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions ①have emerged about how that information should be handled. Employees who work with big data now face responsibilities ②that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Some argue that strict regulations should govern data collection, even if such rules ③slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can ④protects consumers just as effectively without stifling progress. Universities have begun adding data ethics courses to computer science programs, ⑤recognizing that future employees will need to balance innovation with responsibility.

Every day, we leave behind marks of the gases that warm our planet, much like footprints ①left in wet sand. These marks, often called our carbon footprint, come from small choices such as driving, eating, and using electricity. Many students think that only ②small factories create these marks, but ordinary habits at home also matter greatly. For example, turning off lights when leaving a room ③reduces the energy that power plants must produce. Walking or biking to school instead of riding in a car also ④lowers the amount of gas released into the air. In contrast, leaving devices plugged in all night quietly increases our footprint without our notice. Therefore, students who practice these simple habits regularly can ⑤shrink their footprint significantly.

A rational approach to decision-making dictates that only future costs and benefits should influence a choice, since resources already spent cannot be recovered regardless of what is decided next. In practice, however, people routinely allow such irrecoverable expenditures, known as sunk costs, to shape their subsequent decisions, a pattern referred to as the sunk cost fallacy. Economists therefore urge decision-makers to evaluate each choice based solely on its prospective outcomes, treating past expenditures as ___________ to the decision at hand.

Many people believe that building a new habit requires strong willpower or motivation. However, psychologist BJ Fogg argues that habits form more easily when a behavior itself becomes simple to perform. His theory, called the Fogg Behavior Model, states that ___________. When motivation is low, the task must be made extremely easy, 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 least 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 achievable.

Every plastic product carries a small recycling mark, but few students know what these marks mean. Each symbol _______________. For instance, the number one usually stands for clear plastic bottles, while the number five represents thicker containers like yogurt cups. Reading these marks is similar to reading nutrition labels on snacks, which tell you exactly what is inside. Without checking the label, you might buy something unhealthy by mistake. Likewise, throwing plastic away without checking its mark can send a reusable item straight to a landfill. Some marks even show that a material cannot be recycled at all, so it must be sorted separately. Therefore, taking a few seconds to check the mark before throwing something away makes recycling far more effective for everyone involved.

Seatbelts are so woven into the experience of riding in a car that many passengers buckle them without thinking, yet a surprising number of teenagers still skip them for short trips, assuming that a five-minute drive to a friend's house does not carry much risk. (A) In a collision, a body traveling at a moderate speed continues moving forward at that same speed until something stops it, and without a seatbelt, that something is often the windshield or the dashboard. (B) Traffic safety data tell a different story: most fatal crashes occur within a few kilometers of home, on roads drivers know so well that they let their guard down. (C) A seatbelt spreads the force of a sudden stop across the stronger parts of the body, such as the hips and chest, instead of concentrating it on the head and neck.

For example, children and elderly people are especially vulnerable because their bodies cool down less efficiently. Every summer, doctors warn about the danger of heatstroke during long heatwaves, and this condition does not affect everyone equally. ( ① ) Heatstroke happens when the body's temperature rises too high and cannot cool itself down. ( ② ) This condition can be life-threatening if it is not treated quickly. ( ③ ) To prevent heatstroke, drink plenty of water and avoid outdoor activities during the hottest hours of the day. ( ④ ) Wearing light clothing also helps your body stay cool. ( ⑤ ) If symptoms appear, move to a shaded or air-conditioned place immediately.

As a result, your body struggles to adapt, and this can weaken your immune system over time. Air conditioners make summer days more comfortable, but a larger gap between indoor and outdoor temperatures forces your body to face sudden changes again and again. ( ① ) Many people still set the temperature far below the outdoor temperature to cool down quickly, without realizing the risk. ( ② ) However, doctors recommend keeping the difference between indoor and outdoor temperatures within five or six degrees. ( ③ ) This often leads to symptoms such as headaches, fatigue, and a stuffy nose. ( ④ ) To avoid these problems, set a moderate temperature and open a window for a few minutes every hour. ( ⑤ ) Following these tips will help you stay both cool and healthy this summer.
