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.

Whenever someone learns that I spend hours drawing comics that almost nobody else ever sees, they usually ask why I ①bothering, since the work will never be published or praised by a large audience. For a long time, I struggled to answer that question honestly, ②assuming that art only counted as worthwhile once other people recognized it. Watching my younger brother build enormous, pointless block towers purely for the joy of knocking them down, though, ③helped me understand something I had been missing. He never once asked whether his tower was good; he simply needed to build the version of it that existed in his head before he could feel satisfied. Creating something, I now believe, often serves the creator first, ④giving shape to a feeling or idea that would otherwise stay vague and unexpressed. Whether or not anyone else ever sees the result, that private act of shaping an idea into something real still seems ⑤to matter enormously.

Students often groan when a classic novel appears on their reading list, complaining that the language feels old-fashioned and the plot moves too ①slowly. It is true that classic literature can be ②easier to read than a modern bestseller written in casual, everyday language. Yet this very difficulty is part of why classics remain valuable for young readers today. Working through unfamiliar sentence patterns and vocabulary trains the brain to handle ③complex texts, a skill that transfers directly to other subjects and to standardized tests. Beyond language training, classic novels also explore themes such as jealousy, ambition, and loss that have not changed much across ④centuries. Readers often discover that a character written hundreds of years ago struggles with feelings that still feel ⑤familiar today.

Many schools give students a list of recommended books at the start of each year. Choosing these books is not as simple as picking ①well-known titles. Teachers must think about a wide range of student interests, not just their own favorites. A good list should also include stories from ②different cultures and different kinds of characters, so that every student can find someone to relate to. Reading level matters too; a book that is too difficult can make a student ③give up on reading altogether, while a book that is too easy may feel boring. Teachers often ask students for feedback after they finish a book, and they slowly update the list based on what students actually ④ignored. In the end, the best recommended list is not fixed forever; it keeps changing to match the readers it is meant to ⑤serve.

Riding a bicycle is one of the most ①popular ways for teenagers to get around, yet many students still skip the one piece of equipment that could save their life: the helmet. Some argue that a short trip to a nearby store does not require any special protection, since the risk of a serious accident feels ②distant and unlikely. However, most bicycle accidents happen close to home, on familiar streets where riders feel too comfortable to expect danger. A sudden pothole, a car door opening without warning, or a patch of gravel can throw even an experienced cyclist off balance in an ③instant. Wearing a helmet does not prevent a fall, but it dramatically ④increases the chance of a serious head injury when one occurs. For this reason, safety experts insist that a helmet should be treated not as an optional accessory, but as a ⑤basic requirement every time wheels touch the pavement.

Online advertising algorithms analyze enormous amounts of user data to determine which products a person is most likely to purchase. As a result, the ads that appear on a person's screen often feel remarkably specific, sometimes referencing items browsed only minutes earlier. Supporters argue that this level of precision benefits consumers by reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Critics, however, worry that constant exposure to tailored ads can encourage unnecessary spending, since algorithms are specifically designed to identify and exploit individual weaknesses. Because these algorithms operate largely without public oversight, few consumers fully understand how their personal data shapes what they eventually buy. Greater transparency, many experts argue, would ___________.

A growing number of teenagers are joining book clubs that exist only on their phones. These apps let users track pages, write short reviews, and join group chats about a chosen book. The apps also use gentle reminders and reading streaks to keep members motivated. However, a few teachers worry that constant notifications from a reading app can pull attention away from the book itself. Despite this concern, many students report that _______________.

Students who read many books across many different subjects often develop a habit that quieter learners sometimes lack: the habit of comparing new information with what they already know. (A) A student who has read about ancient wars, ocean ecosystems, and modern economics can more easily notice when two different subjects share a similar pattern. (B) This kind of connection-making is closely related to what psychologists call critical thinking, since seeing a familiar pattern in an unfamiliar topic allows a person to ask sharper questions instead of accepting new information at face value. (C) Extensive reading also builds a large mental library of examples, and teachers often notice that widely read students argue more carefully, supporting their opinions with specific examples rather than vague generalizations.

Stairs seem too ordinary to be dangerous, which is why many people treat them carelessly, texting, carrying an armful of books, or skipping two steps at a time. (A) Familiarity encourages a kind of autopilot mode, in which a person stops looking at each step and instead relies on memory of where the stairs should be. (B) Safety officials recommend a few unglamorous habits: keep one hand free, use the handrail, and turn on the light before stepping onto a dark staircase. (C) Emergency room records tell a different story: falls on stairways send more people to the hospital each year than almost any other household accident.

A weekend camping trip promises fresh air and a break from screens, but the same wilderness that makes camping appealing also removes many of the safety nets people rely on without noticing, such as nearby hospitals or cell phone signal. (A) Experienced campers also stress the importance of checking a weather forecast before leaving, since a clear evening sky offers no guarantee against a sudden storm later that night. (B) One of the most overlooked risks is setting up a tent too close to a campfire, since a sudden gust of wind can carry a spark onto dry fabric faster than anyone expects. (C) Food storage is another area where casual habits create danger: leaving snacks inside a tent, rather than in a sealed container away from the sleeping area, can attract wildlife looking for food.
