Smartphones, tablets, and computer screens all emit a significant amount of blue light, a short-wavelength light that our eyes are especially ① sensitive to. During the day, exposure to blue light from the sun helps keep us alert and mentally sharp, which is generally beneficial. At night, however, the same wavelength can interfere with the body's natural preparation for sleep. Specialized cells in the retina ② detect blue light and send signals to the brain's internal clock, ③ suppressing the release of melatonin, the hormone that signals it is time to rest. Studies have found that ④ people who scroll through their phones in bed before sleeping take longer to fall asleep and experience lighter, more easily disrupted sleep than those who avoid screens. Some devices now offer a night mode that shifts the display toward warmer tones, reducing blue light output in the evening. While this feature may help slightly, sleep researchers generally recommend ⑤ limit screen use altogether in the hour before bedtime for the best results.

Modern factories increasingly rely on collaborative robots, often called cobots, ①which are designed to work safely alongside human employees. Unlike traditional industrial robots that operate behind safety cages, cobots use sensors ②detect nearby workers and adjust their movements accordingly. In practice, cobots typically handle repetitive or physically demanding tasks, such as ③lifting heavy parts, while human workers focus on tasks that require judgment. This division of labor increases overall efficiency, since each side ④contributes what it does best. Manufacturers who have introduced cobots report fewer workplace injuries, largely because employees no longer ⑤perform exhausting repetitive motions all day.

Artificial intelligence has begun to play a surprising role in creative industries ①once thought to be uniquely human. Programs can now compose music, generate paintings, and ②draft short stories within seconds. Some artists welcome this technology, ③used AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. Others, however, argue that AI-generated art lacks the emotional depth ④that comes from genuine human experience. Therefore, artists who learn to work alongside AI, rather than compete against it, may find themselves ⑤with a distinct advantage.

Soojin started posting short cooking videos on her phone during her last year of high school, never imagining it could become a career. At first, only a handful of friends watched her clips, and she nearly ①quit after several months without noticeable growth. She kept experimenting, however, adjusting her editing style and posting more ②consistently despite the discouraging numbers. Everything changed when one video demonstrating a simple recipe unexpectedly reached millions of viewers overnight. Within a year, Soojin was earning ③more from her online content than most entry-level jobs would have paid her. Still, she quickly learned that being a creator demanded ④minimal work, since algorithms rewarded frequent uploads and audiences expected fresh content daily. Looking back, Soojin realizes that persistence, rather than luck alone, transformed her hobby into a ⑤demanding profession.

Automation is transforming labor markets more ①quickly than economists predicted a decade ago. Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable ②precision. This shift does not simply eliminate jobs; it also creates roles that never existed before, so technicians who maintain robotic equipment are now in high ③demand. Companies that invested early in automation often report steady increases in productivity, since machines handle repetitive tasks while employees focus on ④creative problem-solving. Without proper retraining support, the benefits of automation may not be shared fairly, ⑤narrowing inequality between skilled and unskilled labor.

Fast fashion refers to ①**cheap**, trendy clothing produced quickly and replaced almost as fast as it is bought. Because these garments are designed to be worn only a few times, huge amounts of fabric end up in landfills every year, and the dyeing process ②**pollutes** rivers near factories. In contrast, a ③**growing** number of brands are turning toward the circular economy, an economic model in which materials are reused, repaired, or recycled instead of being thrown away after a single use. For example, some companies ④**collect** old clothes, break down the fibers, and weave them into new fabric, while others let customers rent outfits for special occasions rather than buying garments they will barely wear. These approaches keep resources circulating within the system longer, ⑤**increasing** demand for raw materials. Therefore, shifting from a throwaway habit toward a circular one may be essential for making the fashion industry sustainable.

When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. However, the concept of climate justice reminds us that the causes and consequences of climate change are distributed ①**evenly** across the globe. Wealthy, industrialized nations have historically released the ②**largest** share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most ③**severe** droughts and floods. This gap between responsibility and suffering raises a serious ④**ethical** question that science alone cannot answer. For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. Therefore, tackling climate change requires more than new technology; it demands ⑤**fair** policies supporting the very communities least responsible for causing the crisis.

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.

Open a music streaming app on any given morning, and a personalized playlist is usually already waiting, assembled overnight from songs the algorithm predicts will match a listener's current mood. (A) Musicians, meanwhile, have mixed feelings about this shift, since a song the algorithm decides not to promote may struggle to reach listeners no matter how well it was written. (B) Listeners often praise the feature for introducing them to artists they never would have searched for on their own, effectively acting as a tireless music scout working around the clock. (C) This prediction relies on far more than genre alone; the system studies skip rates, replay counts, and even the time of day a song is typically played to build a detailed profile of individual taste.

Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. (A) However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide. (B) Supporters argue that the system protects domestic industries and pushes foreign manufacturers toward cleaner methods. (C) The factory facing stricter rules often spends more, which can make its goods pricier than those made elsewhere. To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon was released while producing them.
