Telemedicine, which allows patients to consult doctors through video calls rather than in-person visits, ①have expanded rapidly since its early adoption. Supporters argue that this approach saves patients considerable time and ②makes healthcare accessible to people living in remote areas without nearby hospitals. It has also created new career opportunities, ③since healthcare providers now need staff skilled in digital communication. However, critics contend that virtual appointments cannot fully replace physical examinations, ④which remain essential for detecting certain conditions. Despite such concerns, most healthcare experts believe telemedicine will continue to grow, ⑤complementing rather than replacing traditional in-person care.

A striking proportion of individual investors believe their own stock-picking ability to be above average, a statistical ①impossibility given that only half of any population can genuinely outperform the rest, yet a pattern that persists with remarkable consistency across surveys. This tendency, known as overconfidence bias, leads investors to trade more ②frequently than a more cautious assessment of their own skill would justify. Extensive research comparing the trading records of numerous individual accounts has ③demonstrated that investors who trade most frequently tend to earn substantially ④higher returns than those who trade rarely, largely because transaction costs accumulate and because frequent trading often reflects overconfident reactions to short-term noise rather than genuine insight. Overconfidence also manifests in the tendency to underestimate the range of possible outcomes, causing investors to concentrate their holdings in a small number of assets they feel certain about rather than diversifying across a broader portfolio. Paradoxically, then, the very confidence that motivates investors to act decisively often ⑤undermines the outcomes they are trying to achieve.

City governments increasingly market dense networks of surveillance cameras as a safety upgrade. Yet the same infrastructure that catches criminals also creates a permanent record of where ordinary citizens go about their daily lives. Once a camera network exists, its purpose can quietly expand, often without new public debate. Civil liberties groups argue that _______________.

For much of the twentieth century, memory researchers assumed that once a memory had been consolidated—transformed from a fragile, short-term trace into a stable, long-term representation—it remained essentially fixed, immune to further modification unless the underlying neural circuitry was physically damaged. (A) During this narrow window, which typically lasts only a few hours, the memory can be strengthened, weakened, or even subtly distorted by new information encountered in the interim, after which it must undergo a second round of stabilization, a process now widely referred to as reconsolidation. (B) Consequently, what we experience as a stable recollection may actually be a continuously revised construction, reshaped every time it is summoned into conscious awareness and returned to storage. (C) This assumption, however, was overturned by a body of research demonstrating that the act of retrieval itself can destabilize a previously consolidated memory, rendering it temporarily susceptible to alteration before it is, in a sense, filed away again.

Not all parts of a city experience the same temperature, even when they are located close to one another. (A) Tall buildings packed closely together also block wind, trapping warm air within narrow streets. In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. (B) To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does. (C) On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling.

The classification of platform workers has become one of the most debated issues in modern labor law. (A) For this reason, companies generally prefer classifying these workers as independent contractors rather than full employees. (B) Being classified this way, however, means workers miss out on protections such as minimum wage and paid leave. (C) Employee status requires companies to provide benefits and follow strict labor regulations, which increases operating costs.

The rise of big data has introduced ethical dilemmas that earlier generations of workers never had to consider. (A) Some believe that strict government regulations are necessary, even if such rules slow down innovation and raise costs for businesses. (B) Others argue that companies can regulate themselves effectively through clear ethical training, without needing heavy-handed government intervention. (C) A single careless decision, after all, can expose the private information of millions of people almost instantly.

This kind of outside feedback often reveals strengths you may not notice on your own. Building a career portfolio is a great way to track your growth throughout high school. ( ① ) A portfolio is simply a collection of your achievements, activities, and reflections. ( ② ) Start by choosing a format, such as a folder, a notebook, or a digital file. ( ③ ) Next, include items like club activities, volunteer work, certificates, and sample projects, along with a short reflection for each one. ( ④ ) Update your portfolio regularly instead of waiting until graduation, since memories of small experiences fade quickly. ( ⑤ ) In addition, ask a teacher or mentor to review it occasionally and offer feedback.

In other words, people want the safest outcome for society in theory, but the safest outcome for themselves in practice. When engineers design the software that controls a self-driving car, they inevitably face a question that philosophers have debated for decades. ( ① ) If a crash becomes unavoidable, should the vehicle protect its own passenger at all costs, or should it be programmed to minimize total harm, even if that means steering toward the person inside? ( ② ) Surveys reveal an uncomfortable contradiction: most people say a car should be programmed to save the greater number of lives. ( ③ ) Yet the same people admit they would never buy a vehicle designed to sacrifice its own owner. ( ④ ) This gap between the ideal and the personal choice suggests that ethical programming cannot be settled by public opinion alone. ( ⑤ ) Manufacturers, regulators, and philosophers must instead agree on transparent rules before autonomous vehicles are allowed to make such decisions.

Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often no institution left to appeal to. Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger. ( ① ) In theory, this design distributes power away from any single institution and toward the network as a whole. ( ② ) In practice, however, a small number of large players have come to dominate many blockchain networks. ( ③ ) They control enough computing power or currency to influence outcomes that were supposed to be decided collectively. ( ④ ) Whether decentralization can survive this concentration of power remains one of the technology's most unresolved questions. ( ⑤ )
