RA1 : Many papers you write in college will require you to include quotes from one or more sources. Even if you don’t have to do it,integrating a few quotes into your writing can add life and persuasiveness to your arguments. The key is to use quotes to support a point you are trying to make rather than include them to fill space.
RA2 : The Alaska Pipeline starts at the frozen edge of the Arctic Ocean. It stretches southward across the largest and northernmost state in the Unit-ed states, ending at a remote ice-free seaport village nearly 800 miles from where it begins. It is massive in size and extremely complicated to operate.
RA3 : One of the largest in the world, the pipeline cost approximately $ 8 billion and is by far the biggest and most expensive construction pro-ject ever undertaken by private industry. In fact, no single business could raise that much money, so 8 major oil companies formed a con-sortium in order to share the costs.
RA4: Why do people clap their hands? In most cultures, people clap their hands to show that they like or enjoy something, such as a performance in the theater, a concert or a sport event. In some countries, it is even common for the performer to clap along with the fans. However, the meaning of clapping has changed over time. A long time ago, clapping meant something different than it does today.
RA5: The advent of modern technology has transformed every industry including the hospitality industry. These technologies have enabled busi-nesses to reach more customers and improve customer service. In the hotel industry, the internet is playing a key role and has transformed the way in which hotel operates. Social networking sites such as Twitter and Facebook are playing a dominant role in shaping the strategies of hotels around the globe.
RA6: Some complaints need to be kept confidential in order to safeguard those making or involved in the complaint. However, in some instances we might judge that the complainant will be better served if others are in-volved in the resolution of a complaint. Third parties will only be included in the resolution of confidential complaints on a case-by-case basis and with the agreement of the complainant.
RA7: In recent years, we have all been exposed to dire media reports concerning the impending demise of global coal and oil reserves, but the depletion of another key non-renewable resource continues without receiving much press at all. Helium – an inert, odorless, monatomic element known to lay people as the substance that makes balloons float and voices squeak when inhaled – could be gone from this planet within a generation.
RA8: A number of steps need to be taken in order to avert a costly predica-ment in the coming decades. Firstly, all existing supplies of helium ought to be conserved and released only by permit, with medical uses receiving precedence over other commercial or recreational demands. Secondly, conservation should be obligatory and enforced by a regulatory agency. At the moment, some users, such as hospitals, tend to recycle diligently while others, such as NASA, squander massive amounts of helium. Lastly, research into alternatives to helium must begin in earnest.
RA9: Small populations cannot avoid a certain amount of inbreeding. This is particularly true if there is a very small number of one sex. For exam-ple, if there are only 20 individuals of a species and only one is a male, all future individuals in the species must be descended from that one male. For most animal species, such individuals are less likely to sur-vive and reproduce. Inbreeding increases the chance of extinction.
RA10: Recent research has shown that other factors need to be considered. Aus-tralia’s environment fluctuates enormously from year to year. These fluc-tuations add yet another degree of uncertainty to the survival of many species. Catastrophes such as fire, flood, drought or epidemic may reduce population sizes to a small fraction of their average level. When allow-ance is made for these two additional elements of uncertainty the popu-lation size necessary to be confident of persistence for a few hundred years may increase to several thousand.
