Sample 1

In Australia, the platypus is officially classified as ‘Common but Vulnerable.’ As a species, it is not currently considered to be endangered. However, platypus populations are believed to have declined or disappeared in many catchments 1, particularly in urban and agricultural landscapes. In most cases, the specific underlying reasons for the reduction in numbers remain unknown. Platypus surveys have only been carried out in a few catchments in eastern Australia. It is, therefore, impossible to provide an accurate estimate of the total number of platypus remaining in the wild. Based on recent studies, the average platypus population density along relatively good quality streams in the foothills of Victoria’s Great Dividing Range is only around one to two animals per kilometer of the channel. Because platypus is predators near the top of the food chain and requires large amounts of food to survive (up to about 30% of a given animal’s body weight each day), it is believed that their numbers are most often limited by the availability of food, mainly in the form of bottom-dwelling aquatic invertebrates such as shrimps, worms, yabbies, pea-shell mussels, and immature and adult aquatic insects. Small frogs and fish eggs are also eaten occasionally, along with some terrestrial insects that fall into the water from overhanging vegetation. Catchments are an area of land drained by a creek or river system or a place set aside for collecting water that runs off the land’s surface.

Sample 2

It took 300 workers and 15,000 pieces of iron to complete this massive landmark which now stands at 320 meters tall. The third and highest level offers panoramic views of the City of Paris and sits 276 meters above the ground with three different levels. Today all three levels of the Eiffel Tower are observatory platforms. The first level offers a souvenir kiosk, gallery, and restaurant. The second level provides telescopes, shops, and another restaurant with even more spectacular views; the third provides a gallery featuring the Eiffel Tower’s history, a wax reproduction of Gustave Eiffel, and his original office restoration. Although stairs are still available, lifts commonly take passengers to all three of these levels.

Sample 3

Roller coasters have a long, fascinating history. The direct ancestors of roller coasters were monumental ice slides – long, steep wooden slides covered in ice, some as high as 70 feet – popular in Russia in the 16th and 17th centuries. Riders shot down the slope in sleds made out of wood or blocks of ice, crash-landing in a sand pile. Coaster historians diverge on the exact evolution of these ice slides into actual rolling carts. The most widespread account is that a few entrepreneurial Frenchmen imported the ice slide idea to France. The warmer climate of France tended to melt the ice, so the French started building waxed slides instead, eventually adding wheels to the sleds. In 1817, the Russes a Belleville (Russian Mountains of Belleville) became the first roller coaster where the train was attached to the track (in this case, the train axle fit into a carved groove). The French continued to expand on this idea, coming up with more complex track layouts, with multiple cars and all sorts of twists and turns.
