NASA’s Nuclear Frontier: The Plum Brook Reactor Facility
There are three main types of nuclear reactors: power, research, and test. Research and test reactors as scientific tools are more common than most people realize. While power reactors frequently appear in newspaper headlines and are conspicuous because of their size and power, research reactors can be quietly tucked away, even in the midst of a college campus. Power reactors generate heat, which can easily be converted to other useable forms of energy, such as electricity. Research reactors operate at very low thermal power levels – so low, in fact, that they do not even require any type of forced cooling. They are used to measure nuclear parameters and other characteristics, which can then be used to build other reactors or to design experiments for test reactors. Test reactors are more powerful than research reactors and are able to produce much more intense radiation fields. Though they are still much less powerful than the power reactors, they generate enough heat to require a closed-loop forced-circulation coolant system. This system will remove the heat from the reactor by transferring it to a secondary cooling system, which releases it into the atmosphere through cooling towers.

Her boeuf isn't with the delectable spread's chocolate or hazelnut components, but with the fact that it contains palm oil. Demand for this commodity has driven destruction of tropical forests around the world, especially in Oceania. (From NEWSWEEK, 17/06/2015)
According to French Ecology Minister Ségolène Roya
Mount Roraima, a Mystified Hiking Experience
Hiking here is not hard and you can also get help from the indigenous population, as they organize tour guides in exchange for a small sum of money. If you are on your own however, try to reserve at least four days for this fantastic journey, as there are plenty of things to see and enjoy up there. Mount Roraima is said to have some of _____________________ hiking trails in the world.
You should not leave after 2 p.m. from the village as trekkers are no longer allowed after this hour. At the beginning of your climb, your baggages will be strictly checked and you can not take more than 15 kilos with you. So careful how you organize things. Being given that this is a national park , you are not permitted to take rocks or plants along the way.
The top of the mountain measures 2772m, it offers amazing landscapes and establishing a tent around here is possible. However, you should know the weather changes suddenly in this area so be prepared.

Which alternative below contains an adjective in the
superlative form that best complete the gap in the text?
The mountain is known as a Tepui, which describes a flattopped mountain with vertical sides. Many waterfalls spill off Roraima, and the other Tepuis; nearly everyone has heard of Angel Falls, which spills off another nearby Tepui. There are many interesting plants that grow on the summit, including many carnivorous plants, i.e., ones that eat insects. There is little soil on top because the constant rains wash it away.
Monte Roraima was the first of the Tepuis to be climbed and the credit goes to English botanist Everard Im Thurn on an expedition sponsored by the Royal Geographical Society in 1884. It was his subsequent lectures in England, that are believed to have inspired Sir Arthur Conan Doyle's book 'The Lost World'.
Which word below, extracted from the text, is NOT a verb?
It's a real lost world. On this flat-topped mountain in Venezuela, cut off from civilisation, prehistoric castaways have evolved into unique species found nowhere else on the planet.
Welcome to the Mount Roraima, a spectacular sight which Lonely Planet has explored for the new book The World's Great Wonders.
Waterfalls spilling down sheer cliff faces into clouds. Labyrinths of stone pinnacles. Valleys carpeted with crystals. Carnivorous pitcher plants. Exquisite rare orchids.
When you gazed up at the fortress of stone from the base of the mountain, you didn't know what to expect from this plateau floating high above the Amazon jungle. Now that you're on the summit, it feels as if you've stepped into some archaic land. A world untouched by humankind. A forgotten world.
Pitching your tent for the night inside the caves, you hunker down, your dreams filled with images of gushing waterfalls, strange shifting landscapes and prehistoric creatures.
