A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without ① leaving a person groggy afterward. The key lies in timing: naps limited to roughly twenty minutes allow the brain ② to pass through the lightest stages of sleep while avoiding the deeper stages associated with slow-wave activity. If a nap extends much beyond that window, the sleeper risks ③ waking during deep sleep, which produces a foggy, disoriented feeling known as sleep inertia that can persist for thirty minutes or more. Laboratory studies ④ comparing napping and non-napping groups have repeatedly shown that a brief nap improves reaction time and short-term memory almost as effectively as a full night of extra rest. Interestingly, the benefit appears strongest when the nap occurs several hours after waking, since this is when the body's natural dip in alertness makes rest most ⑤ effectively.

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.

Traditional economic models predict that a rational individual offered any positive sum of money, however small, should accept it without hesitation, since even a modest gain is preferable to ①receiving nothing at all. A simple experimental exercise known as the ultimatum game, in which one participant proposes how to split a sum of money and a second participant may either accept or reject the proposed division, consistently ②contradicts this prediction. When the proposer offers a division perceived as unfair, the second participant frequently rejects the offer entirely, leaving both parties with nothing rather than ③accepting an outcome viewed as insulting. This behavior indicates that individuals value fairness as an end in itself, sometimes willingly ④sacrificing material gain to punish perceived exploitation. Neuroscientific investigations complement this finding, revealing that unfair offers ⑤activates brain regions associated with disgust and negative emotion.

Sunny Beach Rentals is now open for the summer season, ①offering a wide range of water equipment for visitors. Customers can rent items such as beach umbrellas, folding chairs, snorkeling gear, and paddleboards ②at affordable daily rates. To rent equipment, visitors simply need to show identification and pay a small deposit, ③which is fully refunded when the items are returned in good condition. Reservations ④made online receive a ten percent discount compared to walk-in rentals. Renters are asked ⑤returning all items by six in the evening, since the shop closes shortly after sunset.

Food poisoning cases increase sharply during the hot summer months, and high temperatures ①allowing bacteria to grow quickly in food that is not stored properly. Make sure that meat, fish, and eggs ②are cooked thoroughly, since undercooked food can carry harmful bacteria. Keep perishable food in the refrigerator, and never ③leave it out at room temperature for more than two hours. It is also important ④to use separate cutting boards for raw meat and vegetables. If you experience symptoms such as stomach pain, ⑤seek medical attention promptly.

The city government has launched a summer energy-saving campaign to ①reduce electricity use during the hottest months. Using fans together with air conditioners cools rooms more efficiently while using ②more power. To prevent blackouts, residents are asked to set air conditioners no lower than twenty-six degrees Celsius, which helps save ③energy. Businesses are asked to dim unnecessary outdoor signs after ten at night. Families who reduce their electricity use by more than ten percent will receive a ④discount on their next bill, which is a nice ⑤reward for their effort.

Before making a purchase, most online shoppers now read reviews written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often seem more trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs have become a serious problem, undermining consumer trust. Platforms that fail to detect these fraudulent posts risk losing credibility with their users, who expect authentic opinions when making decisions. To address this issue, several review platforms have begun using artificial intelligence to identify suspicious patterns. Ultimately, the power of online reviews ___________.

Every morning, our broadcasting club airs a short news program for the entire school. Last Tuesday, I was chosen to read the weather report for the very first time. (A) My partner Minho, who was sitting beside me, quickly slid the script closer to me. I took a deep breath and calmly continued reading from where I had stopped. (B) My hands were shaking as the red light on the camera turned on. Halfway through my sentence, I suddenly forgot the next line completely. For a few seconds, only silence filled the studio, and I could hear my own heartbeat. (C) Somehow, my voice sounded steadier than I expected, and I finished the report smoothly. After the broadcast ended, several classmates told me they had not even noticed the pause. That morning taught me that small mistakes rarely matter as much as we fear.

Storing summer fruit properly can help you avoid waste and enjoy fresher flavors. (A) Berries, however, should not be washed until just before eating, because moisture encourages mold to grow. (B) Watermelon and melon should be kept in the refrigerator once they are cut, since warm air speeds up spoiling. (C) Bananas, unlike most fruit, are best kept on the counter rather than in the refrigerator.

Few of these later buyers, however, possess any independent basis for judging whether the asset's price still bears any relation to its underlying value. A speculative bubble typically begins with a genuine, defensible reason for optimism, such as a promising new technology or an unusually favorable economic environment. ( ① ) Early investors who recognize this genuine opportunity purchase the asset and, as expected, often see its price rise accordingly. ( ② ) As word of these early gains spreads, a second wave of investors enters the market, drawn less by independent analysis than by the simple observation that the price has already climbed. ( ③ ) They are, in effect, purchasing confidence rather than value, trusting that the crowd's continued enthusiasm will sustain or further elevate the price. ( ④ ) This reliance on collective momentum rather than fundamental analysis is precisely what transforms a reasonable initial rally into an unsustainable bubble. ( ⑤ ) When the momentum eventually falters, as it inevitably must, the absence of any solid fundamental foundation leaves the price with nothing to support it.
