Read the text and choose the correct answer for each question below:

Ha Long Bay

Ha Long Bay is a group of offshore islands that is the best example of marine invaded limestone region in the world. The Bay holds over 1,600 islands and islets. There are caves and grottoes, with stalactites and stalagmites. Its limestone pillars are a unique natural feature of great scenic beauty and biological interest. The great extent and the richness of its forms set it apart from many other sites.

Ha Long Bay is an extremely popular destination both for foreigners and Vietnamese: already in the early 1990s it saw over 1 million visitors a year. It is unlikely that the number has decreased over the years - so there will always be about 3,000 other people in the Bay at the same time as you!

The natural beauty of the Bay lay hidden today under a very common fog. As I had already seen the similar karst landscape in China a couple of years before, I certainly said that I was blown away by the beauty of Ha Long Bay. We went onto one of the islands to visit the Surprising Cave - an indeed surprisingly big and beautiful cave with three hollow chambers. We saw some monkeys here too, just outside the cave exit.

Part of the tour was half an hour of kayaking - enough to paddle a full circle around the main area. The views from the kayak I found much more impressive than from the larger boat: you're so tiny then and the peaks rise sharply in front of you. I had a better look at the water too, and cannot say that I saw pollution by plastic or other junk floating around. There is a thin layer of oil on the water in some parts though.

And then it's time to get back in the bus to Ha Noi, another 3.5 hours. The tour was carried out well with good seafood for lunch and I had a satisfying day.

Question: The writer was _______.

A. able to escape from an explosion in Ha Long Bay

B. very impressed by the beauty of Ha Long Bay

C. unable to see Ha Long Bay due to the fog

D. really frightened of visiting the Surprising Cave

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

(1) Iron production was revolutionized in the early eighteenth century when coke was first used instead of charcoal for refining iron ore. Previously the poor quality of the iron had restricted its use in architecture to items such as chains and tie bars for supporting arches, vaults, and walls. With the improvement in refining ore, it was now possible to make cast-iron beams, columns, and girders. During the nineteenth century further advances were made, notably Bessemer’s process for converting iron into steel, which made the material more commercially viable.

(2) Iron was rapidly adopted for the construction of bridges, because its strength was far greater than that of stone or timber, but its use in the architecture of buildings developed more slowly. By 1800 a complete internal iron skeleton for buildings had been developed in industrial architecture replacing traditional timber beams, but it generally remained concealed. Apart from its low cost, the appeal of iron as a building material lay in its strength, its resistance to fire, and its potential to span vast areas. As a result, iron became increasingly popular as a structural material for more traditional styles of architecture during the nineteenth century, but it was invariably concealed.

(3) Significantly, the use of exposed iron occurred mainly in the new building types spawned by the Industrial Revolution: in factories, warehouses, commercial offices, exhibition hall, and railroad stations, where its practical advantages far outweighed its lack of status. Designers of the railroad stations of the new age explored the potential of iron, covering huge areas with spans that surpassed the great vaults of medieval churches and cathedrals. Paxton’s Crystal Palace, designed to house the Great Exhibition of 1851, covered an area of 1.848 feet by 408 feet in prefabricated units of glass set in iron frames. The Paris Exhibition of 1889 included both the widest span and the greatest height achieved so far with the Halle Des Machines, spanning 362 feet, and the Eiffel Tower 1,000 feet high. However, these achievements were mocked by the artistic elite of Paris as expensive and ugly follies. Iron, despite its structural advantages, had little aesthetic status. The use of an exposed iron structure in the more traditional styles of architecture was slower to develop.

According to the passage, iron was NOT used for beams, columns, and girders prior to the early eighteenth century because _____.

A. all available iron was needed for other purposes

B. limited mining capability made iron too expensive

C. iron was considered too valuable for use in public buildings

D. the use of charcoal for refining ore produced poor quality iron
