Scientists have identified certain gene variants that ① appear more frequently among elite endurance athletes than among the general population, along with a separate set that seems to favor explosive, power-based sports such as sprinting. One frequently studied variant, for instance, ② influences the proportion of slow-twitch versus fast-twitch muscle fibers a person naturally develops, a ratio that shapes whether a body leans toward endurance or explosive power. However, researchers caution strongly against ③ interpreting these findings as evidence that athletic greatness is simply inherited. Even athletes who carry every favorable variant identified so far still require years of disciplined training ④ to translate that genetic potential into actual performance, and many elite competitors lack some of these supposedly advantageous variants altogether. Genetics may set a rough ceiling on an individual's ultimate potential, but where any particular athlete lands within that range ⑤ depend overwhelmingly on training quality, nutrition, coaching, and sheer determination.

To compensate for their carbon emissions, many individuals and companies now ①purchases carbon offsets, financial credits that fund projects such as planting trees or building renewable energy plants. The idea is appealing: paying for an equivalent amount of carbon to be absorbed elsewhere should cancel out the harm caused by activities like flying. However, critics argue that this system often ②functions as a convenient excuse for postponing genuine emission cuts rather than achieving them. For example, a newly planted forest may take decades to absorb the promised carbon, and it could later ③burn down or be cut, erasing any benefit. Moreover, some offset projects would have happened anyway, meaning the credits fund nothing truly ④additional. Therefore, relying heavily on offsets allows businesses ⑤to maintain harmful practices while appearing responsible.

Hospitals are increasingly adopting artificial intelligence tools that can scan medical images and flag potential tumors faster and, in some trials, more accurately than experienced radiologists. Patients understandably welcome any technology that catches disease earlier, yet the growing reliance on these tools raises an uncomfortable legal question that hospitals ① have only begun to address. When an AI system misses a diagnosis that a human doctor would likely ② have caught, responsibility becomes difficult to assign. The doctor may argue that they simply trusted a tool the hospital ③ required them to use, the hospital may argue that the software company guaranteed its accuracy, and the software company may argue that no algorithm can ④ expect to be perfect. Until legal systems clarify this chain of responsibility, patients harmed by an algorithmic error may find themselves with no clear party ⑤ to hold accountable.

Yesterday, I ①visited my school's career counselor because I felt confused about my future. I told her that I enjoyed both science and art, but I could not decide which subject ②to pursue. She listened carefully and then asked me a simple question: what activities ③make me lose track of time? She suggested that I try ④combining my two interests by exploring careers such as scientific illustration or product design. Before I left, she reminded me that career paths rarely follow a straight line, so it was fine ⑤explore multiple directions.

Minji spent nearly every evening ①watched Jimin, an online creator who streamed cooking videos and chatted casually with her viewers. Over several months, Minji began to feel as though she truly knew Jimin, ②laughing at her jokes and worrying whenever she mentioned having a difficult week. Whenever Jimin responded to a comment, even a simple one, Minji felt a small thrill of connection, as if they ③were becoming closer friends. One day, Minji excitedly waited outside a fan event, ④hoping that Jimin would recognize her from the countless messages she had sent. However, Jimin greeted her the same way she greeted every other stranger in line, ⑤without any hint of personal recognition.

Many students wonder why club activities ①matter so much for their school life record, a document that summarizes what a student did during each semester. Whenever students take part in a club, their teacher writes a short note describing what role they played and how they grew. For example, a student who organized a club exhibition might be described as someone who showed ②strong leadership and creativity. These notes are not simply a list of activities; they explain the process behind each achievement. Therefore, admissions officers at universities read the record carefully to understand a student's ③genuine interests, not just their grades. In contrast, a club membership with no real participation rarely leaves a ④meaningful impression. This is why teachers encourage students to take a ⑤passive role rather than joining a club only for its name.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. During recent years, this gap became ① impossible to ignore, as families in rural areas or low-income neighborhoods struggled to complete schoolwork that assumed a stable connection and a personal device. Some policymakers initially treated internet access as a ② convenience, comparable to cable television, rather than as infrastructure essential to modern life. That assumption is increasingly being reconsidered, particularly as more essential services move online by default. Closing this divide will require ③ far less than simply distributing devices; it will demand ④ sustained investment in the physical networks that carry information into every home, ⑤ regardless of income or location.

A few years ago, spotting a manipulated video required a trained eye and specialized software. Today, freely available applications allow almost anyone to fabricate convincing fake footage within minutes. Perhaps more troubling than any single fake video is the broader effect on public trust, sometimes called the liar's dividend, in which _______________. In this environment, the mere possibility of manipulation can be almost as damaging as manipulation itself.

Part-time jobs can teach students skills that go far beyond earning money. (A) In contrast, employees who ignore mistakes or blame others often struggle to keep their jobs. (B) Workers who stay calm and take responsibility for errors tend to earn their coworkers' trust. (C) For example, handling a customer complaint well can be a valuable lesson in patience and communication.

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.
