Read the following passage and answer the question below.
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful invaders such as bacteria, viruses, and other pathogens. It operates on two main levels: the innate immune system, which provides a rapid but general response to any perceived threat, and the adaptive immune system, which develops a targeted response specific to a particular pathogen and can retain a memory of it for future encounters. This immune memory is the principle behind vaccination, which trains the immune system to recognize and fight a specific pathogen without the person having to experience the actual disease first. While the immune system is remarkably effective, it can also malfunction, leading to conditions such as autoimmune diseases, where the body mistakenly attacks its own healthy cells, or allergies, where the immune system overreacts to substances that are normally harmless. Researchers continue to study the immune system in hopes of developing better treatments for these disorders.

The pyramids of ancient Egypt, particularly those at Giza, remain some of the most impressive architectural achievements in human history, built more than four thousand years ago without the aid of modern machinery. These massive structures were primarily built as tombs for pharaohs, intended to protect their bodies and possessions for the afterlife, which the ancient Egyptians believed was a continuation of earthly existence. The construction of the pyramids required an extraordinary level of organization, involving thousands of skilled laborers, engineers, and quarry workers who transported and assembled massive stone blocks with remarkable precision. Contrary to a popular but inaccurate myth, historical and archaeological evidence indicates that the pyramids were built by paid laborers and skilled workers rather than slaves. The Great Pyramid of Giza, built for the pharaoh Khufu, remained the tallest man-made structure in the world for thousands of years. Today, the pyramids continue to draw millions of visitors and remain a subject of ongoing archaeological research.

As the world shifts toward renewable energy sources such as solar and wind power, the development of efficient energy storage technology has become increasingly critical. Because renewable sources are intermittent, generating electricity only when the sun shines or the wind blows, batteries are needed to store excess energy for use during periods of low generation. Lithium-ion batteries, widely used in everything from smartphones to electric vehicles, have become the dominant storage technology due to their high energy density and relatively long lifespan. However, researchers are actively exploring alternative battery chemistries, such as solid-state and sodium-ion batteries, which promise improved safety, lower costs, and reduced reliance on scarce materials like cobalt and lithium. Large-scale battery storage facilities are also being built alongside power grids to help balance supply and demand, reducing the need for fossil-fuel-based backup power plants. Continued advances in battery technology are widely seen as essential to achieving a fully renewable and reliable electricity grid.

Glaciers, massive bodies of ice formed over thousands of years, are melting at an accelerating rate due to rising global temperatures, posing serious consequences for both local ecosystems and the wider world. Many communities around the globe depend on glacial meltwater for drinking water, agriculture, and hydroelectric power, particularly during dry seasons when other water sources are scarce. As glaciers shrink, these communities face growing uncertainty about their long-term water supply. Beyond regional impacts, the melting of large ice sheets in Greenland and Antarctica contributes significantly to global sea level rise, threatening coastal cities and low-lying island nations with increased flooding and erosion. Scientists use satellite measurements and on-the-ground observations to track glacier retreat, and the data consistently shows accelerating ice loss across most of the world's glaciated regions. Addressing glacier melt is closely tied to broader efforts to reduce greenhouse gas emissions, since the rate of melting is directly influenced by global temperature trends.

The Olympic Games trace their origins back to ancient Greece, where the first recorded competition was held in the city of Olympia in 776 BCE as part of a religious festival honoring the god Zeus. These ancient games featured events such as running, wrestling, and chariot racing, and were held every four years, a tradition known as an Olympiad. The ancient Olympics continued for nearly twelve centuries before being discontinued during the Roman era. The modern Olympic Games were revived in 1896 in Athens, largely through the efforts of French educator Pierre de Coubertin, who believed international sporting competition could promote peace and understanding between nations. Since then, the Games have grown dramatically in scale, now featuring thousands of athletes from around the world competing in a wide range of summer and winter sports. Despite occasional disruptions due to wars and, more recently, global health crises, the Olympic Games remain one of the most widely watched international events in the world.

Speaking more than one language fluently, a skill known as bilingualism, has been shown by researchers to offer a range of cognitive benefits beyond simple communication advantages. Studies suggest that bilingual individuals often demonstrate improved executive function, including better attention control, task-switching ability, and problem-solving skills, likely because managing two language systems requires constant mental regulation. Some research also indicates that bilingualism may help delay the onset of age-related cognitive decline and conditions such as dementia, though scientists caution that more research is needed to fully understand this relationship. Children raised in bilingual households typically reach language milestones at a similar pace to monolingual children, despite an early misconception that learning two languages simultaneously could cause confusion or delay. Beyond cognitive advantages, bilingualism also offers significant social and cultural benefits, allowing individuals to connect with a broader range of people and better understand different cultural perspectives.
