You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1.

Looking In The Telescope

A. A story is told that around 400 years ago some children were fooling around in an eyeglass shop. They noticed that when they placed lenses one on top of the other, they were able to see a considerable distance. They played around with the concept for a while, experimenting with what happened when they varied the distance between the lenses. Hans Lippershey, the Dutch lens maker who eventually applied for the first telescope patent, credits children as having been his motivation for the invention of the first telescope.

B. The first telescopes built in the early 1600s were very primitive inventions allowing the user to see around 3-times further than the naked eye. It was not too long, sin embargo, until Italian astronomer Galileo heard about the invention ‘that through use of correctly-positioned lenses, allowed people to see things a long way away’. The tools used in the manufacturing of the first refracting telescope were all Galileo needed to know and within 24 hours he had developed a better one. En realidad, the process of improvements Galileo made on Lippershey’s telescope was quite dramatic. Whereas the original version had a magnification of 3, the new telescope had a magnification of around 30. Galileo achieved these extraordinary results by figuring out the combination of the positions of the lenses and also by making his own lenses which were of better quality. Although he originally thought they were stars, the better quality lenses – and some scientific analysis – enabled him to eventually use his telescopes to see the moons of Jupiter. Galileo’s refracting telescopes – so-called due to the way they handled the light that passed through them – were the standard at that time.

C. Some 70 years later, British scientist Isaac Newton, explored the way a prism refracts 1 white light into an array of colours. He recognized that a lens was a circular prism and that the separation of colours limited the effectiveness of the telescopes in use at the time. Newton created a Reflective Telescope, one that used a dish-shaped or parabolic mirror to collect light and concentrate the image before it was visible in the eyepiece. Thus, lenses used for magnification in telescopes were replaced by mirrors. Mirrors have since been the standard for telescopes. En realidad, according to telescope researcher Dr Carl Addams, the basic designs of telescopes have not changed much in the last 100 años. What has changed, sin embargo, is the way technology has been used to improve them. Por ejemplo, the larger telescopes in the world today are around 10 meters in diameter and the mirrors placed within them are so finely polished that even at the microscopic level there are no scratches or bumps on them at all. To achieve such a flawless surface requires a very expensive process that operates with the utmost precision.

The separation or change of direction of a ray of light when passed through a glass of water.

D. The mid-1700s saw the discovery and production of the Achromatic telescope. This type of telescope differed from previous ones in the way it handled the different wavelengths of light. The first person who succeeded in making achromatic refracting telescopes seems to have been the Englishman, Chester Moore Hall. The telescope design used two pieces of special optical glass known as crown and flint Each side of each piece was ground and polished and then the two pieces were assembled together. Achromatic lenses bring two wavelengths – typically red and blue – into focus in the same plane. Makers of achromatic telescopes had difficulty locating disks of flint glass of suitable purity needed to construct them. In the late 1700s, prizes were offered by the French Academy of Sciences for any chemist or glass-manufacturer that could create perfect discs of optical flint glass, sin embargo, no one was able to provide a large disk of suitable purity and clarity.

mi. Corrientemente, the largest telescopes are around eight to ten meters in size. These extremely expensive and sophisticated pieces of equipment are located primarily throughout Europe and America. Dr Addams believes that the telescopes of the future will be a gigantic improvement in what is currently considered state-of-the-art. Telescopes that are 20 o 30 meters in diameter are currently being planned, and there has been a suggestion put forward by a European firm that they would like to build a 100-meter telescope. Says Addams, ‘The quality of the glass needed to build a 100-meter telescope is like building a lens the size of a football field and having the largest bump in that football field being a ten-thousandth of a human hair’. The engineering and technology required to build such a flawless reflective surface are most impressive.

Reading Passage 2

You should spend about 20 minutes on Questions 14 27 which are based on Reading Passage 2.

A. The intense rate of change in the world gives rise to numerous new products – many of them electronic. What is brand new and state-of-the-art one month is quickly relegated to old model’ status the next. Within the world of computing, this frenetic pace of change has led to millions of out-dated, worthless products. Keystone, an American-based research company reported. En 2005, one computer became obsolete for every new one introduced in the die market. By the year 2010, experts estimate that in the USA there will be over 500 million obsolete computers. Most of these computers will be destined for landfills, incinerators or hazardous waste exports.’ Old, outdated keyboards, monitors and hard drives all combine to produce what is now widely known as ‘e-waste’ and the way to appropriately dispose of them is proving to be a challenge.

B. Most computers are a complicated assembly of hundreds of different materials, many of which are highly toxic. Most computer users are unaware that these toxic metals, acids, plastics, and other substances have been shown to be the cause of various blood diseases and cancers, Amongst workers involved in the recycling of computer products, there has been a proliferation of blood diseases Printed circuit boards, por ejemplo, contain heavy metals such as antimony, silver, chromium, zinc, lead, tin and copper. Environmentalist Kieran Shaw estimates there is hardly any other product for which the sum of the environmental impacts of raw material, extraction, industrial refining and production, use and disposal is so extensive as for printed circuit boards.

C. Workers involved in the disposal of computers via incineration are themselves being exposed to significantly high levels of toxicity. Copper, por ejemplo, is a catalyst in the release of harmful chemicals when exposed to the high tempera lures of incineration. In US and Canadian environments, incineration is one of the greatest sources of heavy metal contamination of the atmosphere. Desafortunadamente, another form of incineration, smelting, can present dangers similar to incineration. Concerns have been expressed that the Noranda. The smelter in Quebec, Canada is producing atmospheric pollutants from the residual presence of plastics in the e-scrap.

D. In an effort to explore other alternatives, landfills have been tried, Studies have shown, sin embargo, that even the best landfills are not completely safe, In feet, the shortcomings of dealing with waste via modern landfills are well documented. The main ‘offender’ in the area of metal leaching is mercury. In varying degrees, mercury escapes or leaches from certain electronic devices such as circuit breakers, condensers and computer circuit boards into the soil, According to Phil Stevenson, managing director of CleanCo a recycling plant in the UK, ‘Everyone knows that landfills leak – it has become common knowledge Even the best, state-of-the-art landfills are not completely tight throughout their lifetimes, to one degree or another, a certain amount of chemical and metal leaching occurs The situation is far worse for older or less stringent dump sites. If uncontrolled fires are allowed to burn through these landfill areas, other toxic chemicals such as lead and cadmium are released.

mi. An overwhelming majority of the world’s hazardous e-waste is generated by the industrialized market economies. Because labour costs are cheap and government regulations in some countries are decidedly lax, the exporting of e-waste has been practised as another method to deal with its disposal. In the USA for example, Datatek, a research company, estimated that it was 12 times cheaper to ship old computer monitors to China than it was to recycle them. Data on the prevalence of this activity is scarce due to past bad publicity and dealers of e-scrap not bothering to determine the final destination of the products they sell in 1989 the world community established the Basel Convention on the Transboundary Movement of Hazardous Waste for final Disposal to stop the industrialized nations of the OECD from dumping their waste on and in less-developed countries.

F. Europe has taken the lead on e-waste management by requiring governments to implement laws controlling the production and disposal of electrical products. The European Union (EL) lias drafted legislation on Waste from Electrical and Electronic Equipment (the WE EE Directive) based on a concept known as Extended Producer Responsibility (EFR), Essentially, EFR places the responsibility’ of the production and disposal squarely on the shoulders of the producers of electronic products, it requires that producers consider carefully the environmental impact of the products they bring to the marketplace. The aim of EPR is to encourage producers of electrical equipment to prevent pollution and reduce resource and energy use at each stage of the product file cycle. The lead-in Europe has been necessary’ because WERE is about three times higher than the growth of any other municipal waste streams.

GRAMO. WEE legislation will phase-out the use of toxic substances such as mercury, cadmium, and lead in electronic and electrical goods by the year 2008. It will require producers of electrical equipment to be responsible financially for the collection, recycling, and disposal of their products. It has stipulated that products containing any lead, mercury, cadmium, and other toxic substances must not be incinerated. It encourages producers to integrate an increasing quantity of recycled material in any new products they produce. En realidad, between 70% y 90% by weight of all collected equipment must be recycled or re-used. These directives will go a long way toward improving the e-waste problem in Europe and other governments of the world should look seriously at the implementation of some or all of the legislation.

You should spend about 20 minutes on Questions 28-40 which are based on Reading Passage 3.

Preparing For The Threat

A. It is an unfortunate fact that over the past 20 pars, alrededor 260 million people a year have been affected by natural disasters around the world. Regrettably, a vast majority of the victims of this staggering number are from developing countries. Whether it be earthquakes, tornadoes, floods, volcanoes or tsunamis, over the past twenty years, natural disasters have been happening more frequently and affecting more people than ever before. It follows that the international community should address the issue of ‘disaster preparedness’ and establish a process by which natural disasters are dealt with.

B. En diciembre 26, 2004, a massive earthquake centred off the coast of the Indonesian island of Sumatra caused a series of deadly tsunamis in the Indian Ocean. The damage from this extraordinary disaster was estimated to be in the vicinity of the US $ 13 billion – the equivalent to the combined GDP 1 of the world’s developing countries for an entire year. In a matter of seconds, the tsunami waves wiped out the long years of struggle for development, and the world was once again reminded of the fearsome and destructive power of natural disasters.

C. Gross Domestic Product is the total value of goods and services produced by a country in a year. The United Nations designated the 1990s as the International Decade for Natural Disaster Reduction and has been active in promoting and developing international cooperation on disaster preparedness. The UN’s Yokohama Strategy for a Safer World: Guidelines for Natural Disaster Prevention, Preparedness and Mitigation was adopted in 1994. Among the guidelines, developing countries are encouraged to organize and implement their domestic resources for disaster reduction activities and donor developed countries are encouraged to give greater priority to disaster prevention, mitigation, and preparedness in their assistance programs and budgets, including through increasing financial contributions.

D. In January 2005 the UN World Conference on Disaster Reduction (WCDR) met in Kobe, Hyogo Prefecture to discuss and debate how the international community should address issues of disaster preparedness and mitigation. The meeting itself attended by over 4,000 delegates representing some 168 countries occurred almost 10 years to the day after the Great Hanshin earthquake in Kobe. The January meeting of the WCDR in Kobe provided experts and scientists from over 150 countries, government officials, Non- Government Organisation (NGOs) and United Nations representatives with an opportunity to review the Yokohama Strategy. It recorded on the 2005-15 Yokohama Strategy Action Plan that participant countries and agencies should work over the next 10 years to reduce vulnerability to natural disasters. The Action Plan encourages as a first step, the integration of disaster prevention programs in all development and policy-making plaits for all countries. Jim Edgeland, UN representative stated, “Disaster risk reduction is not an additional expense – it is an essential investment in our common future, but the benefits of this investment will be calculated not only in dollars or euros or yen saved, but most importantly, in saved lives in every corner of the globe.”

mi. Perhaps the most significant work done at the WCDR meetings was the drafting and adoption of the Hyogo Declaration, This document expresses the united determination of the international community to rely not only on advanced technology or facilities for disaster preparedness but on a people-centred early warning system. The people-centred system requires effective communication and education in the building of disaster-resilient countries and communities. As the intergovernmental panels of the WCDR were meeting, the Great Hanshin-Awaji Earthquake Forum was also underway. The earthquake measuring a magnitude of 7.3, led to the Joss of over 6,400 lives and widespread destruction affecting some 460,000 households. This public forum offered a variety of sessions, during which the lessons learned from the disastrous earthquake were discussed. Earthquake expert Professor Tomohiro Kawata said, “Because this disaster happened over a decade ago, the memory of the devastation can be forgotten.

F. Part of our gathering here today is to make sure that we do not forget what happened back in 1995.’’ Also included were some personal stories from the earthquake victims themselves. Earthquake victim Kumiko Nagota told attendees that her house collapsed in the Kobe earthquake and she was trapped under it. She tried to call for help but after a while, she lost her voice and just had to wait there until help came. Attendees were told of the bow the town mobilized to facilitate recovery and reconstruction. An exhibition hall showed pictures of mounds of rubble produced by the earthquake as well as a display of objects donated by earthquake victims including a broken clock and a child’s toy that moulted in the fires caused by the earthquake. Said Kawata, “As well as being a memorial, our facility and, indeed this forum, is a place to learn from earthquake experiences and incorporate the things we learned into our preparations for future disasters”. During the forum, it was agreed that in May 2005, a new hub for the coordination of international disaster recovery support activities would be established in Kobe.
