Last spring, Mina joined the school environmental club because she wanted ①to make a difference. At first, she felt nervous about speaking in front of the other members. However, the club leader, ②which had been recycling for years, welcomed her warmly. Every Friday, the members walked around the school ③picking up trash near the playground. Mina soon realized that this weekly habit was like ④watering a small plant every day. For example, a single plastic bottle left outside could take hundreds of years to disappear. Therefore, the club decided to place clear recycling bins in every classroom. In contrast to her early doubts, Mina began to feel proud of the changes she noticed. Her classmates started separating cans and paper without ⑤being reminded by teachers. By the end of the semester, Mina had become an active member.

Air conditioners make summer days more comfortable, but ①using them incorrectly can harm your health. Doctors recommend keeping the difference between indoor and outdoor temperatures within five or six degrees, ②which helps your body adjust more easily. A larger gap forces your body ③to adjust constantly, which can weaken your immune system. This sudden change often ④lead to symptoms such as headaches and fatigue. It is also helpful ⑤to open a window for a few minutes every hour.

Researchers who study teenagers have found a ①strong link between how well students sleep and how well they perform in school. Students who sleep fewer than seven hours a night tend to score ②lower on tests of memory and attention than those who sleep eight or nine hours, even when the two groups study for the same number of hours. One explanation is that sleep plays an active role in learning: during certain stages of sleep, the brain replays and strengthens information encountered during the day, converting fragile short-term memories into more ③durable long-term ones. When sleep is cut short, this consolidation process is interrupted before it can finish, so material that seemed well understood the night before often feels ④unfamiliar the next morning. For this reason, some schools have begun ⑤confirming early start times, reasoning that an extra hour of sleep might do more for test scores than an extra hour of studying ever could.

When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow ①immediately or wait for two. Researchers found that children who waited ②longer showed better academic performance and self-control years later. This ability to ③resist an immediate reward in favor of a larger future one is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks. At first, resisting small purchases felt surprisingly ④easy, especially when her friends were eating out. After three months, however, she had ⑤saved enough to buy a bicycle she had wanted for over a year.

Heatstroke happens when the body's temperature rises too ①high and cannot cool itself down. This condition can be completely ②harmless if it is not treated quickly. Drinking plenty of water helps keep your body ③cool. Wearing light, loose clothing also helps ④release heat from your skin. If you notice symptoms such as dizziness, you should move to a shaded place ⑤immediately.

Behavioral economists use the term status quo bias to describe a tendency to prefer the ①present situation over a new alternative, even when the alternative would bring greater benefits. This bias helps explain why many households ②rush to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels ③safe and requires no immediate effort. In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem ④risky compared with doing nothing. For example, a neighborhood association might repeatedly ⑤postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on designing programs that make the first step feel easy.

This goal-tracking app helps you set New Year goals and build healthy habits step by step. First, open the app and create an account using your email address. Next, tap the plus button to add a new goal, and choose how often you want to ①practice it. The app will then send a ②rare reminder at the time you select each day. Every time you complete a task, tap the checkmark, and the app will ③record your streak automatically. You can also view a simple chart that shows your ④progress over the past month. Finally, share your progress with a friend inside the app for extra ⑤motivation and support.

The subscription economy refers to a business model in which consumers pay a recurring fee to access goods or services rather than owning them outright. This model has expanded rapidly beyond entertainment platforms into areas such as clothing, food, and even transportation. One major reason for this growth is ___________, since subscribers no longer need to make repeated purchasing decisions once they sign up. Another reason is that companies benefit from predictable revenue, which allows them to plan production and marketing more efficiently than with one-time sales. However, some critics argue that subscriptions encourage people to pay for services they barely use, quietly draining their monthly budgets.

This evidentiary standard, ironically, has made behavioral interventions more rigorously tested than many of the traditional programs they were designed to complement. Government adoption of behavioral insights has generally been governed by a strict evidentiary standard: officials demand proof that a proposed intervention works before authorizing its use. ( ① ) This demand led to the routine use of randomized controlled trials, in which a proposed change is tested on a small population before being rolled out more broadly. ( ② ) Such trials allow policymakers to determine with reasonable confidence whether an intervention produces the intended effect before committing significant public resources to it. ( ③ ) Many long-standing government programs, by contrast, were implemented decades ago without ever being subjected to comparably rigorous evaluation. ( ④ ) Behavioral units within government have, as a result, gradually earned a reputation for evidence-based rigor that extends well beyond their original, narrow mandate. ( ⑤ ) That reputation has, in turn, given behavioral approaches an outsized voice in policy discussions relative to their still-modest budgets.

Whole, uncut melons, however, can be stored at room temperature until you are ready to eat them. Summer brings a wide variety of delicious fruits, but many of them spoil quickly in the heat. ( ① ) Knowing how to store fruit properly can help you avoid waste and enjoy fresher flavors. ( ② ) Fruits such as watermelon and melon should be kept in the refrigerator once they are cut, since exposure to warm air speeds up spoiling. ( ③ ) Berries are especially delicate and should not be washed until just before eating, because moisture encourages mold to grow. ( ④ ) Bananas, on the other hand, turn black quickly in cold air, so they are best kept on the counter. ( ⑤ ) Wrapping cut fruit tightly in plastic wrap also helps keep it fresh longer.
