Read the following passage and mark the letter A, B, C or D on you answer sheet to indicate the correct answer to each of the questions.  SCIENTIFIC DISCOVERIES      A satellite is best understood as a projectile, or an object that has only one force acting on gravity. Technically speaking, anything that crosses the Karman Line at an altitude of kilometers (62 miles) is considered in space. However, a satellite needs to be going fast — at least 8 km (5 miles) a second - to stop from falling back down to Earth immediately.       If a satellite is traveling fast enough, it will perpetually "fall" toward Earth, but the Earth's curvature means that the satellite will fall around our planet instead of crashing back on the surface. Satellites that travel closer to Earth are at risk of falling because the drag of atmospheric molecules will slow the satellites down. Those that orbit farther away from Earth have fewer molecules to contend with.       There are several accepted "zones" of orbits around the Earth. One is called low-Earth-orbit, which extends from about 160 to 2,000 km (about 100 to 1,250 miles). This is the zone where the ISS orbits and where the space shuttle used to do its work. In fact, all human missions except for the Apollo flights to the moon took place in this zone. Most satellites also work in this zone.       Geostationary or geosynchronous orbit is the best spot for communications satellites to use, however. This is a zone above Earth's equator at an altitude of 35,786 km (22,236 mi). At this altitude, the rate of "fall" around the Earth is about the same as Earth's rotation, which allows the satellite to stay above the same spot on Earth almost constantly. The satellite thus keeps a perpetual connection with a fixed antenna on the ground, allowing for reliable communications. When geostationary satellites reach the end of their life, protocol dictates they're moved out of the way for a new satellite to take their place. That's because there is only so much room, or so many "slots" in that orbit, to allow the satellites to operate without interference.       While some satellites are best used around the equator, others are better suited to more polar orbits - those that circle the Earth from pole to pole so that their coverage zones include the north and south poles. Examples of polar-orbiting satellites include weather satellites and reconnaissance satellites.  (Source: https://www.space.com/24839-satellites.html)  Which of the following best serves as the title for the passage?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.       During times of crisis, people find themselves faced with lifestyle changes. One of the earliest and most noticeable changes seen during the Covid-19 lockdown was how we consume media-and especially how we read.       People tend to find comfort in certain books, and reading habits and genre preferences can change during periods of stress. This helps to explain why much genre fiction has roots in times of significant social, political or economic upheaval. Gothic literature is, in part, a British Protestant response to the French Revolution.       Respondents generally reported that they were reading more than usual. This was largely due to having more free time (due to being furloughed, or not having a commute or the usual social obligation or leisure activities). This increased reading volume was complicated for those with caring responsibilities. Many people with children reported that their reading time had increased generally because of their shared reading with children, but had less time than normal for personal reading. Reading frequency was further complicated by a quality vs. quantity snag. People spent more time reading and seeking escape, but an inability to concentrate meant they made less progress than usual. In short, people spent more time reading but the volume they read was less.       Unsurprisingly, lockdown also made re-reading a physical necessity for some. Some respondents noted how they were unable to visit the library or browse at the bookshop for new books. Others reported that they simply wished to save money. On the other hand, the participants who reported re- reading less than normal during the lockdown period wanted to use their newfound time to seek out new topics and genres.  What does the passage mainly discuss?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.       It is estimated that by 2050 more than two-thirds of the world's population will live in cities, up from about 54 percent today. While the many benefits of organized and efficient cities are well understood, we need to recognize that this rapid, often unplanned urbanization brings risks of profound social instability, risks to critical infrastructure, potential water crises and the potential for devastating spread of disease. These risks can only be further exacerbated as this unprecedented transition from rural to urban areas continues.       How effectively these risks can be addressed will increasingly be determined by how well cities are governed. The increased concentration of people, physical assets, infrastructure and economic activities mean that the risks materializing at the city level will have far greater potential to disrupt society than ever before.       Urbanization is by no means bad by itself. It brings important benefits for economic, cultural and societal development. Well managed cities are both efficient and effective, enabling economies of scale and network effects while reducing the impact on the climate of transportation. As such, an urban model can make economic activity more environmentally-friendly. Further, the proximity and diversity of people can spark innovation and create employment as exchanging ideas breeds new ideas. But these utopian concepts are threatened by some of the factors driving rapid urbanization. For example, one of the main factors is rural urban migration, driven by the prospect of greater employment opportunities and the hope of a better life in cities. But rapidly increasing population density can create severe problems, especially if planning efforts are not sufficient to cope with the influx of new inhabitants. The result may, in extreme cases, be widespread poverty. Estimates suggest that 40% of the world's urban expansion is taking place in slums, exacerbating socio-economic disparities and creating unsanitary conditions that facilitate the spread of disease.      The Global Risks 2015 Report looks at four areas that face particularly daunting challenges in the face of rapid and unplanned urbanization: infrastructure, health, climate change, and social instability. In each of these areas we find new risks that can best be managed or, in some cases, transferred through the mechanism of insurance.  The word “that" in paragraph 4 refers to __________.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 39 to 43.       It was widely reported last year that sales of guidebooks are falling fast, thanks to developments in the Internet and mobile phones. It makes sense. Why bother taking a heavy book with you when you can down all the information you need to your phone as you walk around the cathedral?       Writing a new book about a place is a rewarding job, but one that is becoming a rarity. Publishers are more concerned with keeping existing books up to date than bringing out new ones in an already crowded market. This is understandable, since every guidebook is actually out of date as soon as it is published. It may have been researched a year before being printed and it could have sat on the bookshop shelf for a year or two, so its information might be three years old by the time the reader uses it in practice. It is hardly surprising, therefore, that some publishers are inviting almost as much in updating and redesigning their books as they did creating them. Updating guides is nowadays a good way for new writers to get started.       But if the Internet via a mobile phone can deliver information just as well as printed paper but much faster, at almost no cost, is there a future for printed guidebook? Other books you read at home, but a travel guide's main purposes for urgent reference when you're desperate to find accommodation or somewhere to eat. Using a modern cellphone, any traveller can now enjoy a “paperless holiday”. Want to know the opening times of the museum? Look them up online. Need some information on the ancient building you're standing in? Download it.  Which could be the best title for the passage?
