As more businesses move their operations online, cyberattacks ①have become one of the most serious threats facing modern companies. Hackers now target everything from small retail websites to massive financial institutions, ②stealing sensitive data or demanding ransom payments. These specialists design systems ③that detect suspicious activity, patch vulnerabilities before criminals can exploit them, and train employees to recognize phishing attempts. Unlike many technical fields, cybersecurity requires constant learning, ④since hackers continually develop new methods to bypass existing defenses. Universities have responded by creating specialized degree programs, while many companies now ⑤offers scholarships to attract students into this growing field.

Retailers frequently rely on sales events to boost short-term revenue, but the psychology behind these promotions is more complex than simple discounting. When a price is crossed out and replaced with a lower number, consumers instinctively ①perceive the new price as a bargain. This technique, ②known as anchoring, shapes how shoppers judge value by comparing prices rather than evaluating a product on its own merits. Limited-time sales further intensify this effect, since a ticking clock ③encourage rushed decisions that leave little room for careful comparison. Retailers also use phrases such as "while supplies last" to suggest scarcity, even when inventory ④remains plentiful. Over time, frequent sales can actually train customers ⑤to wait for discounts rather than buy at full price.

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 ①trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly ②more 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, ③undermining consumer trust. Platforms that fail to detect these fraudulent posts risk ④gaining credibility with their users, who expect authentic opinions when making decisions. Ultimately, the power of online reviews depends entirely on their perceived ⑤honesty.

When Mina graduated from college five years ago, she had never even heard the term "data scientist." Everything changed when a small tech startup, which was building an app to predict traffic patterns, hired her to analyze massive amounts of data. Mina quickly discovered that she loved turning raw numbers into insights that helped real people make better decisions. Within two years, ___________, as companies in every industry realized how valuable data could be. Today, Mina leads a team of ten analysts, mentoring young graduates who are drawn to a field that barely existed when she began her own career.

As technology continues to reshape nearly every profession, the idea of finishing education after graduation has become outdated. Workers who once expected their initial training to last an entire career now find that skills can become obsolete within just a few years. Lifelong learning, therefore, ___________. Many professionals now take short online courses, attend workshops, or earn new certifications while continuing to work full-time.

Modern advertising increasingly relies on personal data collected from users' browsing habits, search histories, and social media activity. Companies argue that this approach benefits consumers by showing advertisements that are more relevant to their actual interests rather than random, generic promotions. However, many critics contend that this level of tracking raises serious concerns about privacy, since users rarely understand how extensively their behavior is being monitored. Some algorithms can predict purchasing decisions before consumers themselves are consciously aware of them, which feels unsettling to many people. Furthermore, personalized advertising can trap users in a narrow bubble, repeatedly showing them similar products and limiting their exposure to alternatives. Given these competing concerns, policymakers must ___________.

3D printing has found practical applications across a surprisingly wide range of fields. (A) In medicine, for example, hospitals now create prosthetic limbs that are precisely tailored to each patient's body. (B) The automotive industry has also adopted the technology, using it to manufacture lightweight parts that improve fuel efficiency. (C) Even small businesses have gained access to manufacturing capabilities that were once available only to large corporations with significant capital.

Introducing cobots into a factory requires careful planning to ensure both safety and productivity. (A) Once installed, however, cobots must be closely monitored, since their sensors can occasionally malfunction in noisy or crowded environments. (B) Engineers must first program the robots to recognize the exact boundaries of each worker's movement space. (C) After this initial setup, cobots can be integrated gradually, starting with simple tasks before taking on more complex ones.

주어진 문장: This explains why progress often feels rapid and motivating during the earliest days of learning something new. The twenty-hour rule proposes that years of practice are not needed to become skilled at a new activity. ( ① ) Only about twenty hours of effort are needed to reach a useful level. Unlike theories claiming true mastery requires ten thousand hours, this rule targets a more modest goal. That goal is simple competence for everyday use. ( ② ) According to supporters, practicing any new skill produces the fastest visible improvement, since a beginner has room to grow. ( ③ ) Someone learning guitar can typically strum simple chords and follow a basic song within twenty hours of daily practice. ( ④ ) Likewise, a language learner may soon order food or ask directions without years of formal study. ( ⑤ ) Advocates emphasize that the twenty hours must be deliberate and focused, broken into short daily sessions rather than one long stretch. The hours should be aimed at fixing weaknesses rather than repeating what one already knows.

주어진 문장: Yet not every worker benefits equally from these changes. Automation is transforming labor markets more quickly than economists predicted a decade ago. ( ① ) Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable precision. ( ② ) This shift does not simply eliminate jobs; it also creates roles that never existed before, such as technicians who maintain robotic equipment. ( ③ ) Companies that invested early in automation often report steady increases in productivity, since machines handle repetitive tasks while employees focus on creative problem-solving. ( ④ ) Policymakers argue that retraining programs are essential to help displaced workers move into emerging fields. ( ⑤ ) Without such support, the benefits of automation may not be shared fairly across society.
