Reading Comprehension

Read the following passage and answer the question below. The invention of the telephone in 1876 by Alexander Graham Bell marked a turning point in human communication, allowing voices to be transmitted across distances instantaneously for the first time. Before the telephone, long-distance communication relied heavily on the telegraph, which could only send coded messages rather than actual speech. Bell's device converted sound waves into electrical signals that could travel through wires and be converted back into sound at the receiving end. Early telephones required operators to manually connect calls through switchboards, a labor-intensive process that limited how quickly calls could be placed. Over the following decades, automatic switching systems, direct dialing, and eventually digital and wireless technology transformed the telephone from a novelty into an essential tool of daily life. Today's smartphones, which combine calling capability with countless other functions, trace their origins directly back to Bell's original invention nearly one and a half centuries ago. Question: According to the passage, who invented the telephone?

Read the following passage and answer the question below. Plastic pollution has become one of the most visible and pervasive environmental problems of the modern era, with millions of tons of plastic waste entering the world's oceans every year. Unlike organic materials, plastic does not fully biodegrade; instead, it breaks down into smaller fragments called microplastics, which can persist in the environment for hundreds of years. These microplastics have been found in even the most remote parts of the ocean, as well as in the tissues of marine animals that mistake plastic fragments for food. Ingested plastic can cause injury, starvation, or death in marine species, and there is growing concern about the potential effects of microplastics entering the human food chain through seafood consumption. In response, many countries have introduced bans on single-use plastic items such as bags and straws, while researchers continue developing biodegradable alternatives. Public awareness campaigns have also encouraged individuals to reduce plastic consumption and improve recycling habits. Question: What is the passage primarily about?

Read the following passage and answer the question below. At its height in the thirteenth century, the Mongol Empire was the largest contiguous land empire in history, stretching from Eastern Europe to the Pacific Ocean. Founded by Genghis Khan, the empire expanded rapidly through a combination of highly skilled cavalry, innovative military strategy, and a willingness to adopt useful technologies and administrative practices from conquered peoples. Despite its reputation for brutal conquest, the Mongol Empire also facilitated unprecedented levels of trade and cultural exchange across Asia and Europe, a period sometimes referred to as the Pax Mongolica, or Mongol Peace. This era of relative stability allowed merchants, missionaries, and travelers, such as Marco Polo, to journey safely along trade routes like the Silk Road. After Genghis Khan's death, the empire eventually fragmented into several smaller khanates, each governed by his descendants, though the cultural and administrative legacy of Mongol rule continued to influence the regions it once controlled for centuries afterward.

Read the following passage and answer the question below. Mars has long captured human imagination as a potential destination for future exploration and even settlement, owing to its relative proximity to Earth and similarities in certain geological features. Since the 1960s, dozens of missions, including orbiters, landers, and rovers, have been sent to study the Martian surface, atmosphere, and potential for past or present life. Rovers such as Curiosity and Perseverance have discovered evidence suggesting that Mars once had liquid water flowing on its surface, raising the possibility that microbial life could have existed there billions of years ago. Current Martian conditions, however, are extremely hostile to life as we know it, with a thin atmosphere, freezing temperatures, and high levels of radiation due to the lack of a protective magnetic field. Space agencies and private companies alike are now developing plans for crewed missions to Mars, though significant technical and logistical challenges, including radiation exposure and the long journey time, remain to be solved.

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. Question: What is the passage primarily about?

Read the following passage and answer the question below. 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. Question: What is the passage primarily about?
