One man who was particularly affected by this subject was Gerard Morgan-Grenville. As Morgan-Grenville travelled round earning his living as a gardener, he noticed signs of the damage that was being done to the countryside around him. It wasn't long before Morgan-Grenville decided that he had to do something about this situation.

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.Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to expand, it will negatively affect one after another of Earth’s ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and runoff of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have irrevocably redirected the course of evolution.Certainly, there have been periods in Earth’s history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only 0.01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt-time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments.Question:With which of the following statements would the author be most likely to agree?

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 As heart disease continues to be the number-one killer in the United States, researchers have become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and "life in the fast lane" have long been known to contribute to the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and quite surprising. Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 A.M. and 10:00 A.M. In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is triggered.

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 questionsThe days of the camera-toting tourist may be numbered. Insensitive travelers are being ordered to stop pointing their cameras and camcorders at reluctant local residents. Tour companies selling expensive trips to remote corners of the world, off the well-trodden path of the average tourist, have become increasingly irritated at the sight of the visitors upsetting locals. Now one such operator plans to ban clients from taking any photographic equipment on holidays. Julian Mathews is the director of Discovery Initiatives, a company that is working hand-in-hand with other organizations to offer holidays combining high adventure with working on environmental projects. His trips are not cheap; two weeks of white-water rafting and monitoring wildlife in Canada cost several thousand pounds. Matthews says he is providing 'holidays without guilt', insisting that Discovery Initiatives is not a tour operator but an environmental support company. Clients are referred to as 'participants' or 'ambassadors'. 'We see ourselves as the next step on from eco-tourism, which is merely a passive form. of sensitive travel - our approach is more proactive.' However, says Matthews, there is a price to pay. 'I am planning to introduce tours with a total ban on cameras and camcorders because of the damage they do to our relationships with local people. I have seen some horrendous things, such as a group of six tourists arriving at a remote village in the South American jungle, each with a video camera attached to their face. That sort of thing tears me up inside. Would you like somebody to come into your home and take a photo of you cooking? A camera is like a weapon; it puts up a barrier and you lose all the communication that comes through body language, which effectively means that the host communities are denied access to the so-called cultural exchange.' Matthews started organizing environmental holidays after a scientific expedition for young people. He subsequently founded Discovery Expeditions, which has helped support 13 projects worldwide. With the launch of Discovery Initiatives, he is placing a greater emphasis on adventure and fun, omitting in the brochure all references to scientific research. But his rules of conduct are strict. 'In some parts of the world, for instance, I tell people they should wear long trousers, not shorts, and wear a tie, when eating out. It may sound dictatorial, but I find one has a better experience if one is well dressed. I don't understand why people dress down when they go to other countries.' Matthews' views reflect a growing unease among some tour companies at the increasingly cavalier behaviour of well-heeled tourists. Chris Parrott, of Journey Latin America, says: 'We tell our clients that indigenous people are often shy about being photographed, but we certainly don't tell them not to take a camera. If they take pictures without asking, they may have tomatoes thrown at them.' He also reports that increasing numbers of clients are taking camcorders and pointing them indiscriminately at locals. He says: 'People with camcorders tend to be more intrusive than those with cameras, but there is a payoff - the people they are filming get a tremendous thrill from seeing themselves played back on the viewfinder.' Crispin Jones, of Exodus, the overland truck specialist, says: 'We don't have a policy but, should cameras cause offence, our tour leaders will make it quite clear that they cannot be used. Clients tend to do what they are told. Earthwatch, which pioneered the concept of proactive eco-tourism by sending paying volunteers to work on scientific projects around the world, does not ban cameras, but operates strict rules on their use. Ed Wilson, the marketing director of the company, says: 'We try to impress on people the common courtesy of getting permission before using their cameras, and one would hope that every tour operator would do the same. People have to be not only environmentally aware but also culturally aware. Some people use the camera as a barrier; it allows them to distance themselves from the reality of what they see. I would like to see tourists putting their cameras away for once, rather than trying to record everything they see.'Question:What is Matthews keen for clients to realize?
