Communication scholar Elisabeth Noelle-Neumann proposed the spiral of silence theory to explain why certain opinions dominate public discussion while others fade into invisibility. According to this theory, individuals constantly ②observe their surrounding environment to judge which opinions are widely accepted and which are not. When people sense that their own view belongs to a minority, they often choose ③to stay silent rather than risk social isolation or criticism. This silence, however, creates a distorted impression that the minority opinion is even rarer than it actually is, ①discouraged additional supporters from speaking up. Over time, this cycle spirals downward, allowing the dominant opinion ④to appear increasingly unanimous while dissenting voices disappear from visible conversation. Social media platforms can intensify this spiral, since visibility metrics make popular opinions instantly noticeable while unpopular ones ⑤remain hidden.

A liver no longer has to sit inside a human body to be studied ①closely. By coaxing stem cells to organize themselves within a nutrient-rich gel, scientists can now grow ②miniature three-dimensional structures called organoids, which reproduce much of the architecture and function of a real organ despite being no larger than a grain of rice. Unlike flat cultures grown on a plastic dish, which ③preserve many of the cues that guide normal development, organoids let cells interact in three dimensions much as they would inside the body, yielding tissue that behaves in strikingly ④realistic ways. This fidelity has made organoids invaluable for testing how a drug affects human tissue before any patient is exposed, sparing researchers much of the ⑤burden of relying on animal models alone.

Our school's volunteer club, Helping Hands, tries to make small acts of kindness feel ①natural. Each month, students visit a nearby nursing home and spend an afternoon talking with elderly residents. For example, they read newspapers aloud or just listen to old stories from the residents. In addition, members ②collect used books and toys from classmates and donate them to a community center downtown. Some students feel ③confident before their first visit, unsure of what to say to strangers. However, most discover that a ④warm smile works better than perfect words. Therefore, the club's real goal is not just finishing hours for a report card. Instead, it teaches members that caring for others grows into a ⑤lasting habit, like watering a plant daily. By the end of the year, many students say the club changed how they see their community.

During the hottest weeks of summer, the city operates free cooling centers for anyone who needs a break from the heat. These cooling centers, located in community halls and public libraries, provide ___________. Anyone can use the facilities, but they are especially helpful for elderly people and those without air conditioning at home.

Facial recognition software has moved rapidly into shopping malls, schools, and apartment buildings. Proponents note that it can unlock doors and speed up identity checks far faster than any human guard. Independent studies, however, have repeatedly found that many commercial systems perform less accurately on women and people with darker skin tones, which means that _______________. Several cities have already reported cases in which an innocent person was detained based on a flawed match.

The gig economy, in which people take on short-term or freelance jobs instead of full-time positions, has grown rapidly over the past decade. This model offers clear advantages: workers can choose when and how much they work, and businesses can hire help only when they actually need it. For many young people entering the job market, gig work provides valuable flexibility that traditional employment rarely allows. However, gig workers often ___________, which full-time employees typically receive. Because their income can fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently.

A documentary director named Mira first traveled to a remote Arctic glacier to film its towering cliffs of blue ice, which seemed frozen in time. Standing before the massive wall, she assumed such an enormous structure could hardly change within a lifetime. Five years later, however, she returned to the very same coordinates, expecting her camera to capture an identical scene. Instead, she discovered that the glacier had retreated so dramatically that the ice cliffs, once visible from her original position, had nearly disappeared, leaving bare rock and pools of meltwater behind. Comparing the two sets of footage side by side, Mira realized that _______________. This encounter convinced her that climate change, which she had previously regarded as a distant statistic, was in fact an urgent process reshaping landscapes before her eyes.

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.

Succeeding in an online course requires more than simply signing up. (A) In addition, picking a course with good reviews and a clear structure prevents wasted time. (B) Without a classroom schedule, learners must manage their own time and stay motivated. (C) For this reason, experts suggest setting a fixed weekly study schedule.

This is a decision, in short, that no single person should be allowed to make alone. The discovery of CRISPR gene-editing technology gave scientists a tool precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. ( ① ) Yet the same precision that makes CRISPR so promising also makes it dangerous in the wrong hands. ( ② ) Editing a gene in a sperm, egg, or early embryo does not simply change one patient. ( ③ ) It alters the genetic code passed down to every future generation. ( ④ ) Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. ( ⑤ ) Critics worry, however, that this line will become harder to enforce than it is to draw.
