Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. During sustained physical activity, the body ①releases a protein called brain-derived neurotrophic factor, which supports the growth of new neurons and ②strengthens connections between existing ones, particularly in regions associated with memory and learning. Studies comparing physically active students to sedentary peers have repeatedly found that the active group ③performing better on tests of attention and problem-solving, even when the exercise session ends well before the test begins. Researchers believe that exercise increases blood flow to the brain, ④delivering oxygen and nutrients more efficiently, while also reducing levels of stress hormones that can interfere with clear thinking. These findings have encouraged some schools ⑤to schedule exercise before demanding academic classes.

Until last spring, Minji rarely thought twice about ①tossing a paper cup into the trash after finishing her coffee. Environmental issues seemed distant, something scientists and politicians should handle rather than an ordinary student like her. That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially ②expected finding boring. Instead, watching seabirds mistake plastic fragments for food ③left her strangely unsettled, and she found herself thinking about the assignment long after class ended. The next morning, almost without deciding to, she ④slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. It felt like a small, meaningless gesture at first. However, as weeks passed, she realized that consistently choosing the tumbler, ⑤declining a plastic straw, and reusing a shopping bag were quietly adding up. Small choices, she discovered, become meaningful once repeated.

Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, ①which often requires expensive molds and long production times, 3D printers can create complex objects directly from digital files within hours. This flexibility allows companies ②to produce small batches of customized products without the massive costs typically associated with mass production. Hospitals now use 3D printing to create prosthetic limbs ③tailored precisely to individual patients, while automakers use it to build lightweight parts that reduce vehicle weight. Small businesses, too, have benefited enormously, since the technology ④lower the barrier to entry for entrepreneurs. As printing materials improve and machines become faster, the technology is expected ⑤to play an increasingly central role in future manufacturing.

Many students ①take a career aptitude test at some point in high school. This test, ②which is designed to measure a person's interests and strengths, does not simply tell students which job to choose. Instead, it helps them understand themselves better. For example, a student ③who enjoy solving problems might discover a hidden interest in engineering. However, the results should ④be used only as a guide, not as a final answer. Therefore, students should treat the test as a useful starting point for ⑤exploring various career paths, rather than a fixed decision.

Sunny Beach Rentals is now open for the summer season, ①offering a wide range of water equipment for visitors. Customers can rent items such as beach umbrellas, folding chairs, snorkeling gear, and paddleboards ②at affordable daily rates. To rent equipment, visitors simply need to show identification and pay a small deposit, ③which is fully refunded when the items are returned in good condition. Reservations ④made online receive a ten percent discount compared to walk-in rentals. Renters are asked ⑤returning all items by six in the evening, since the shop closes shortly after sunset.

When engineers design the software that controls a self-driving car, they face a question philosophers have debated for decades: should a crashing vehicle protect its own passenger, or minimize total harm even at the passenger's expense? Surveys reveal an uncomfortable contradiction: most people say a car should be programmed to save the greater number of lives, yet the same people admit they would never buy a vehicle designed to sacrifice its own owner. This suggests that _______________. Manufacturers, regulators, and philosophers must instead agree on transparent rules before autonomous vehicles are allowed to make such decisions.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. During an internship, he helped design a small satellite intended to monitor crop health from orbit, a project that combined engineering with agricultural science. He realized that ___________. After graduation, Daniel joined a startup developing lunar landing equipment, a job that barely existed when he first imagined his future career.

When Suji transferred to a new school in March, she knew no one in her class and felt lonely during lunch and breaks. Her homeroom teacher suggested _______________. Suji signed up for the photography club, though she had never taken photography seriously before. At the first meeting, older members taught her how to adjust a camera and find a good angle. Because everyone shared photos and gave friendly feedback each week, Suji gradually felt more comfortable with the other members. One rainy afternoon, a fellow member, Hana, invited her to photograph the flooded schoolyard together. They laughed while trying to keep their cameras dry, and that moment grew into a real friendship. By the end of the semester, Suji had a small group of friends who understood her sense of humor.

As the metaverse develops, entirely new categories of professional work are emerging alongside it. (A) Virtual event planners, for instance, now organize concerts and conferences that take place entirely within digital platforms. (B) Some skepticism remains, since the technology has not yet attracted the enormous user base that early predictions promised. (C) Despite this uncertainty, major companies continue to invest heavily, betting that virtual spaces will eventually rival physical venues in importance.

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.
