By the early nineteenth century – the start of the railway age – men such as John McAdam and Thomas Telford had created a British road network totalling some 200,000 km, of which about one sixth was privately owned toll roads called turnpikes. In the first half of the nineteenth century, many roads in the US were built to the new standards, of which the National Pike from West Virginia to Illinois was perhaps the most notable. In the twentieth century, the ever-increasing use of motor vehicles threatened to break up roads built to nineteenth-century standards, so new techniques had to be developed.On routes with heavy traffic, flexible pavements were replaced by rigid pavements, in which the top layer was concrete, 15 to 30 centimetres thick, laid on a prepared bed. Nowadays steel bars are laid within the concrete. This not only restrains shrinkage during setting, but also reduces expansion in warm weather. As a result, it is, possible to lay long slabs without danger of cracking

For the second question, we find the answer in the second line which says “In the first half of the nineteenth century, many roads in the US were built to the new standards, of which the National Pike from West Virginia to Illinois was perhaps the most notable”. So the answer is “nineteenth”.

For the third question, we find the answer in the fourth line which says “On routes with heavy traffic, flexible pavements were replaced by rigid pavements”. So the answer is “rigid”.

For the fourth question. We find the answer in the fifth line which says “Nowadays steel bars are laid within the concrete”. So the answer is “steel”.

The trend today is to refer to marine algae used as food as ‘sea-vegetables’. The main species used in Ireland at present are dulse, carrageen moss, and various kelps and wracks. Dulse – also known as dillisk in a number of areas – is a red alga that is eaten on both sides of the North Atlantic. 

For the second question, we find the answer in the third line which says “Seaweeds come in three basic colors”. So the answer is “three”.

For the third question, we find the answer in the fourth line which says “Red and brown algae are almost exclusively marine”. So the answer is “marine”.

For the fourth question,  we find the answer in the fourth line which says “green algae are also common in freshwater and in terrestrial situations”. So the answer is “terrestrial”.

11. Brood chamber

For the second question, we find the answer in the third and fourth line which says “These temporary hive extensions contain frames of empty comb for the bees to fill with honey.” So the answer is “frames”.

For the third question, we find the answer in the sixth line which says “To prevent the queen from crawling up to the top and laying eggs, a screen can be inserted between the brood chamber and the supers.” So the answer is “screen”.

For the fourth question, we find the answer in the sixth line which says “To prevent the queen from crawling up to the top and laying eggs, a screen can be inserted between the brood chamber and the supers.” So the answer is “brood chamber”.
