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.

Last New Year's Day, I wrote three goals in my diary: reading more books, exercising regularly, and saving money for a bicycle. Today, exactly one year later, I opened that old page and smiled at how much ①has changed. I did not finish all twelve books I had planned, but I read six, ②which was still more than the year before. Saving money was harder than I expected, since unexpected expenses ③kept appearing. My exercise habit became the biggest surprise, and I now run almost every morning without ④feeling forced. Looking back, I realized that progress does not always match the original plan, and what matters more is that I kept trying, adjusted my methods, and ⑤to learn something new about myself along the way.

Communication scholar Elisabeth Noelle-Neumann proposed the spiral of silence theory to explain why certain opinions dominate public discussion while others fade into invisibility. According to this theory, individuals constantly ②observe their surrounding environment to judge which opinions are widely accepted and which are not. When people sense that their own view belongs to a minority, they often choose ③to stay silent rather than risk social isolation or criticism. This silence, however, creates a distorted impression that the minority opinion is even rarer than it actually is, ①discouraged additional supporters from speaking up. Over time, this cycle spirals downward, allowing the dominant opinion ④to appear increasingly unanimous while dissenting voices disappear from visible conversation. Social media platforms can intensify this spiral, since visibility metrics make popular opinions instantly noticeable while unpopular ones ⑤remain hidden.

Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only ①abandon about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, which ②restricts how many meaningful connections a person can cognitively manage. In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far ③exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships are ④close or emotionally supportive. Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely ⑤unnoticed.

Our school is starting a New Year Goal-Setting Campaign to help everyone begin the year with ①vague direction. During the first week of January, every student will receive a small goal card in homeroom class and write one ②personal goal along with two simple steps. After completing the card, students must ③submit it to their homeroom teacher by January 9th. All goal cards will then be ④displayed on the bulletin board outside the library, so students can encourage one another. Students who show clear progress will receive a small prize, which we hope will ⑤motivate everyone to keep trying.

Jihun wanted to start stretching every day but kept forgetting no matter how many notes he left himself. (A) After a month, he no longer needed to think about it, because the smell of coffee alone reminded him to stretch. (B) He decided to try habit stacking by connecting the new habit to something he already did without fail each morning. (C) Since he never skipped making coffee before school, he began stretching for five minutes while the coffee machine ran.

Career aptitude tests come in many different forms today, and schools use them for various purposes. (A) Some tests focus on personality, asking students how they usually react in different situations. (B) Because of this variety, it is important to understand what each test actually measures before taking it. (C) Other tests focus on specific skills, such as logical thinking or verbal ability.

Goal-setting theory has influenced not only classrooms but also workplaces around the world. (A) Many companies now train managers to set specific quarterly targets rather than simply asking employees to 'do their best.' (B) As a result, employees often report clearer priorities and a stronger sense of accomplishment. (C) These targets typically include measurable numbers, such as sales figures or project deadlines.

Riding a bicycle during summer vacation is fun, but a few safety habits are essential. (A) It is also important to wear bright or reflective clothing so that drivers can see you clearly. (B) Before you ride, always check that your tires are properly inflated and your brakes work well. (C) Finally, choose bike paths or quiet streets whenever possible, rather than busy roads with heavy traffic.

Turning this tide has proven far harder than creating it, and not merely for scientific reasons. Every time an antibiotic kills off a population of bacteria, a handful of cells carrying a random mutation that resists the drug are left behind to multiply without competition. ( ① ) Repeated over decades, across hospitals, farms, and households worldwide, this simple process of natural selection has produced strains of bacteria that survive treatments once considered reliably effective. ( ② ) The pharmaceutical industry, meanwhile, has slowed the pace at which new antibiotics reach the market, since a drug meant to be taken for only a week or two rarely earns back the enormous cost of developing it. ( ③ ) Researchers are therefore searching in unconventional places, screening soil microbes and ocean sediment for molecules that kill bacteria through new mechanisms. ( ④ ) Even genetic databases are now mined for such molecules, ones resistant strains have not yet learned to evade. ( ⑤ ) Some scientists have also revived an older approach, using viruses that infect only bacteria to hunt down resistant strains with a precision no broad-spectrum drug could ever match.
