Every light ①left on in an empty room wastes electricity that could have powered something useful elsewhere. For example, a single classroom light left on overnight can waste enough energy ②to charge dozens of phones. This habit is similar to ③leave a faucet running while you brush your teeth, where water flows out for no reason. However, when an entire school ④forms this habit together, the total amount of ⑤saved energy becomes significant.

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.

Imagine two travelers preparing for the same trip: one ① agrees to fly after watching news coverage of a recent plane crash, while the other books a flight without hesitation. Statistically, air travel remains far ② safer than driving the same distance by car, yet vivid, emotionally charged images tend to ③ dominate human judgment more powerfully than dry statistics ever could. This tendency, in which people estimate how likely an event is based on how easily examples come to mind rather than on actual data, quietly shapes countless everyday decisions. News broadcasts that repeatedly feature rare disasters can leave viewers convinced that such events are ④ common, even though official records clearly show the opposite. Advertisers and politicians alike ⑤ exploit this pattern, knowing that a single striking anecdote often persuades audiences more effectively than pages of careful statistics ever manage to.

Bacteria have been cutting up invading viral DNA for billions of years, long before any scientist thought to borrow the trick for use in a laboratory. The CRISPR-Cas9 system relies on a short guide RNA that matches a specific DNA sequence, _______________. Once Cas9 arrives at the target site, it slices both strands of the DNA helix, and the cell's own repair machinery rushes in to mend the cut, often introducing a small change in the process. By supplying the cell with a template during this repair step, scientists can direct that machinery to insert a specific new sequence rather than merely disabling the original gene. What once required years of painstaking work to alter a single gene can now be accomplished within days.

Minjun used to leave half of his lunch tray full of untouched rice and vegetables every day. Last spring, his class started a campaign called "Clean Plate Day" to reduce food waste. At first, Minjun thought the campaign sounded boring and unnecessary for someone like him. However, his teacher explained that leftover food thrown away every day adds up to a huge amount of waste. She compared uneaten food to _______________. This comparison surprised Minjun because he had never thought about food that way before. He decided to take only what he could finish and to try new vegetables slowly. Within a few weeks, his tray was almost always empty, and he felt proud of the change. Other students noticed his effort and began doing the same thing.

The rise of green jobs illustrates how environmental policy can reshape entire industries. (A) However, critics note that shifting from fossil fuel jobs to green jobs is not always straightforward, since the two require different sets of skills. (B) These positions, ranging from solar panel installation to energy-efficient building design, have grown especially fast in countries investing heavily in renewable energy. (C) To address this gap, governments are introducing training programs that help workers transition smoothly between industries.

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

Software development teams are especially known for missing their own deadlines by wide margins. (A) A team asked to estimate a new project usually imagines everything proceeding smoothly, without bugs, meetings, or unexpected requests. (B) To avoid repeating this mistake, some teams now review how long their last three similar projects actually took before setting a new deadline. (C) Because this imagined version rarely matches reality, the original deadline is missed almost every time, often by weeks or months.

주어진 문장: Once he missed a single day, he found it much easier to miss the next one as well. Jihun made a resolution to study English for two hours every day. ( ① ) For the first three days, he studied exactly as planned and felt proud of himself. ( ② ) On the fourth day, however, he skipped his study time because he was too exhausted. ( ③ ) Within a week, his resolution had disappeared completely. ( ④ ) Feeling disappointed, Jihun talked to his older sister, who suggested that he try a smaller, more realistic goal instead of a large one. ( ⑤ ) Following her advice, Jihun changed his plan to studying English for only twenty minutes each night, and this small goal felt less overwhelming.

This reveals an uncomfortable truth about the underlying business model itself. Social media platforms rarely show users a neutral stream of information. ( ① ) Instead, recommendation algorithms are optimized to maximize engagement, and content that provokes strong emotion tends to hold attention longer than balanced reporting ever could. ( ② ) Researchers describe this as a distorted mirror: the platform reflects not society as it truly is, but a version shaped by whatever keeps people scrolling. ( ③ ) Some platforms have experimented with reducing the visibility of outrage-driven content. ( ④ ) Yet these experiments consistently saw user engagement drop. ( ⑤ )
