When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers ①belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed dramatically, as private companies began ②launching satellites and building reusable rockets. Daniel studied aerospace engineering, ③drawing to the idea that space exploration was no longer limited to a few national agencies. During an internship, he helped design a small satellite ④intended to monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts and technicians ⑤familiar with international space regulations.

Before making a purchase, most online shoppers now read reviews ①written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often ②seem more trustworthy than promotional claims. Research shows that products with a large number of positive reviews ③sell significantly more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs ④has become a serious problem, undermining consumer trust. To address this issue, several review platforms have begun ⑤using artificial intelligence to identify suspicious patterns.

A flexitarian is someone who mainly ①eating plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock ②produces a significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at ③trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it ④allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, ⑤believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

On the first day of winter break, my friend Yuna and I sat in a cafe and talked about the new year ahead. Instead of ①making separate plans, we decided to write our goals together on one sheet of paper. Yuna wanted ②improving her English speaking, while I wanted to wake up earlier every morning. We agreed ③to text each other every night to report what we had done that day. Yuna, ④who noticed my short replies, called me instead of just texting. Because we supported each other through difficult moments, both of us ⑤successfully reached our goals by spring.

Two years ago, I began volunteering at an animal shelter near my neighborhood on weekends. My tasks included feeding animals, cleaning cages, and helping visitors choose a pet to adopt. Over time, I noticed how much I ①enjoyed calming nervous or injured animals. One rainy afternoon, a frightened puppy refused to eat, and I sat quietly beside it for over an hour until it finally ②relaxed. Watching the puppy trust me changed something inside me. I began researching careers in veterinary medicine and animal behavior, subjects I had ③frequently considered before. My volunteer work, which started as a simple ④hobby, slowly turned into the ⑤clearest career direction I had ever found.

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive ①predictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is ②disappointing or thrilling. Consequently, users often refresh their feeds ③compulsively, hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies ④deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about ⑤manipulating users' brains for profit.

Retailers use a variety of techniques designed to encourage customers to make unplanned purchases. Placing small, inexpensive items near checkout counters, for example, tempts shoppers who are already waiting in line with little else to do. Online stores achieve a similar effect through countdown timers that create a false sense of urgency, suggesting that a deal will vanish within minutes. Bright colors, cheerful music, and pleasant scents are also carefully chosen to put customers in a relaxed mood, making them less likely to think critically about their spending. Critics argue that these tactics ___________. Supporters of the industry insist that such techniques merely make shopping more enjoyable and are not inherently deceptive.

After a strenuous workout, muscle fibers experience thousands of microscopic tears, and the body immediately begins a repair process that depends heavily on amino acids, the building blocks that protein supplies. (A) Waiting too long to eat, however, can slow this recovery, since a muscle's sensitivity to amino acids gradually declines once that window closes. (B) Even so, eating an enormous quantity of protein in a single sitting will not speed things up any further, because the body can only use a limited amount at once, burning or storing the rest. (C) This is precisely why sports scientists recommend consuming protein within a couple of hours after a workout, while the muscle is still especially receptive to it.

The subscription economy has changed the way many people think about ownership. (A) As a result, companies can predict their income more accurately and plan their operations accordingly. (B) Rather than buying products outright, consumers increasingly prefer paying small recurring fees for continued access. (C) This shift benefits businesses as well, since steady monthly payments create a stable source of revenue.

She explained that sitting in a cold, air-conditioned room for too long can make people feel weak and achy. Last week, I started feeling tired and had a mild headache every afternoon at school. ( ① ) At first, I thought I was just stressed about exams, but my mother told me it might be air-conditioning sickness. ( ② ) After doing some research, I learned a few simple ways to prevent it. ( ③ ) First, I began carrying a light jacket to wear indoors, and I made sure to drink warm water instead of only cold drinks. ( ④ ) I also started stretching and walking around every hour instead of sitting still all day. ( ⑤ ) Within a few days, my headaches disappeared, and I felt much more energetic.
