When Mina graduated from college five years ago, she had never even heard the term "data scientist." She had studied statistics simply because she ①enjoying solving puzzles with numbers. Everything changed when a small tech startup, ②which was building an app to predict traffic patterns, hired her to analyze massive amounts of data. Mina quickly discovered that she loved ③turning raw numbers into insights that helped real people make better decisions. Within two years, demand for professionals like her ④had exploded, as companies in every industry realized how valuable data could be. Today, Mina leads a team of ten analysts, ⑤mentoring young graduates who are drawn to a field that barely existed.

Long before cognitive scientists possessed the tools to observe the brain directly, Donald Broadbent proposed an influential model suggesting that the human capacity to process incoming sensory information is ①constrained by a structural bottleneck through which only a single stream of input can pass at any given instant. According to this filter theory, multiple channels of stimulation, such as competing voices in a crowded room, are initially registered at a ②deep, physical level, but only one channel is selected for further, meaning-based analysis while the rest are blocked from advancing beyond that early filter. Although later researchers challenged the ③rigidity of this early selection mechanism, pointing to instances in which unattended information, such as one's own name, nevertheless breaks through and captures awareness, the core insight that attention imposes a genuine processing limit rather than a mere matter of willpower has remained remarkably ④durable. This basic bottleneck principle continues to inform contemporary explanations of why multitasking so reliably ⑤degrades performance on demanding tasks.

A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock produces a significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that _______________.

Last spring, a small cosmetics brand opened a pop-up store in a busy shopping district for just two weeks. Rather than displaying products in the usual manner, the team designed the space to resemble a colorful garden, inviting visitors to explore and take photographs. Word spread quickly through social media as customers shared images of the unusual setting with their friends and followers. Lines formed outside the store within days, even though the products themselves were already available online. Curious about this success, a marketing researcher later interviewed several visitors, who explained that the temporary nature of the event made the experience feel special and worth attending in person. Many admitted they had never previously purchased from the brand but decided to buy something simply to remember the visit. When the two weeks ended, the brand reported a significant increase in both sales and social media followers. Encouraged by these results, ___________.

Strong summer sunlight can seriously damage your skin if you are not careful, because ___________. To protect your skin, apply sunscreen with a high SPF before going outside, and reapply it every two hours. Wearing a hat and sunglasses also helps shield your face and eyes from direct sunlight.

Generative AI systems learn to write, draw, and compose by studying enormous collections of existing human work, much of which was created without the artists' knowledge or consent. (A) Critics respond that the comparison breaks down at scale, since a single AI model can absorb millions of works in days and compete with the very artists who trained it. (B) Supporters of the technology argue that this process resembles how a human student learns by studying the masters. (C) Courts around the world are now being asked to decide whether training an algorithm on copyrighted material counts as fair use or as infringement.

Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly through a shared, tamper-resistant ledger. (A) In practice, however, a small number of large players have come to dominate many blockchain networks, controlling enough power to influence outcomes that were supposed to be decided collectively. (B) In theory, this design distributes power away from any single institution and toward the network as a whole. (C) Critics note a further irony: when something goes wrong, there is often no institution left to appeal to, since the system was designed to eliminate central authority.

The discovery of CRISPR gene-editing technology gave scientists a tool precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases. (A) Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. (B) Yet editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation. (C) Critics worry, however, that as the technology becomes cheaper and more widely available, this line will become harder to enforce than it is to draw.

The broadcasting workshop turned out to be more difficult than most students expected. (A) By the second day, though, most students began to enjoy the challenge as their confidence grew. (B) On the first day, many students felt nervous simply standing in front of a camera. (C) This growth was largely due to instructors who gave detailed feedback instead of simple praise.

주어진 문장: Without independent verification, however, such labels can mean almost anything the company wants them to mean. Many companies today advertise their products as environmentally friendly, yet not all of these claims are accurate. ( ① ) This practice, known as greenwashing, involves exaggerating or fabricating a product's positive impact on the environment. ( ② ) Some brands print vague terms such as "natural" or "eco-conscious" on packaging without providing any evidence to support these labels. ( ③ ) Consumers, who are increasingly concerned about climate change, often trust such claims without questioning them closely. ( ④ ) As a result, they may pay higher prices for products that are no more sustainable than ordinary alternatives. ( ⑤ ) Therefore, governments should establish clear standards that require companies to prove their environmental claims with verifiable data.
