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

The technology of the North American colonies did not differ strikingly from that of Europe, but in one respect, the colonists enjoyed a great advantage. Especially by comparison with Britain, Americans had a wonderfully plentiful supply of wood.

The first colonists did not, as many people imagine, find an entire continent covered by a climax forest. Even along the Atlantic seaboard, the forest was broken at many points. Nevertheless, all sorts of fine trees abounded, and through the early colonial period, those who pushed westward encountered new forests. By the end of the colonial era, the price of wood had risen slightly in eastern cities, but wood was still extremely abundant.

The availability of wood brought advantages that have seldom been appreciated. Wood was a foundation of the economy. Houses and all manner of buildings were made of wood to a degree unknown in Britain. Secondly, wood was used as fuel for heating and cooking. Thirdly, it was used as the source of important industrial compounds, such as potash, an industrial alkali; charcoal, a component of gunpowder; and tannic acid, used for tanning leather.

The supply of wood conferred advantages but had some negative aspects as well. Iron at that time was produced by heating iron ore with charcoal. Because Britain was so stripped of trees, she was unable to exploit her rich iron mines. But the American colonies had both iron ore and wood; iron production was encouraged and became successful. However, when Britain developed coke smelting, the Colonies did not follow suit because they had plenty of wood and besides, charcoal iron was stronger than coke iron. Coke smelting led to technologic innovations and was linked to the emergence of the Industrial Revolution. In the early nineteenth century, the former colonies lagged behind Britain in industrial development because their supply of wood led them to cling to charcoal iron

Bài dịch

Nền công nghệ của các thuộc địa Bắc Mỹ đã không có sự khác biệt rõ rệt so với châu Âu, nhưng xét ở khía cạnh khác, thực dân được hưởng một lợi thế lớn hơn. Đặc biệt là khi so sánh với nước Anh, người Mỹ đã có một nguồn cung cấp gỗ tuyệt vời.

Không như nhiều người tưởng tượng, việc khai hoang đầu tiên không tìm ra một lục địa hoàn toàn bị rừng cây bao phủ. Ngay cả dọc theo bờ biển Đại Tây Dương, rừng cây bị gián đoạn ở nhiều điểm. Tuy nhiên, tất cả các loại cây tốt được lan truyền, và qua các thời kỳ đầu thuộc địa, những người đi về phía tây đã bắt gặp khu rừng mới. Đến cuối thời kỳ thuộc địa, mặc dù giá gỗ có tăng nhẹ ở các thành phố phía đông, nhưng lượng gỗ vẫn cực kì dồi dào.

Những lợi ích từ việc sử dụng gỗ mang lại đã không được đánh giá cao. Gỗ là nền tảng của kinh tế. Nhà cửa và các tòa nhà được xây dựng từ gỗ ở mức chưa từng thấy ở Anh. Thứ hai là, gỗ được sử dụng làm nhiên liệu để sưởi ấm và nấu ăn. Thứ ba, nó được sử dụng như một nguồn quan trọng trong các hợp chất công nghiệp quan trọng, chẳng hạn như kali, kiềm công nghiệp; than củi, một thành phần của thuốc súng; và axit tannic, sử dụng công nghệ thuộc da.

Nguồn gỗ này mang lại nhiều lợi ích nhưng đồng thời cũng đem đến những khía cạnh tiêu cực. Sắt tại thời điểm đó đã được sản xuất bằng cách nung quặng sắt với than củi. Bởi vì Anh đã bị lấy hết mất cây, nó không thể khai thác mỏ sắt phong phú của mình được. Trong khi đó các thuộc địa của Mỹ có cả quặng sắt và gỗ; sản xuất sắt được khuyến khích và trở nên thành công. Tuy nhiên, khi Anh phát triển việc luyện kim bằng than cốc, các thuộc địa đã không làm theo bởi vì họ có nhiều gỗ và bên cạnh đó, sắt luyện từ than củi tốt hơn sắt luyện từ than cốc. Việc luyện kim bằng than cốc dẫn đến những cải tiến trong công nghệ và liên quan đến sự xuất hiện của các cuộc cách mạng công nghiệp. Vào đầu thế kỷ XIX, các thuộc địa cũ của Anh tụt hậu trong phát triển công nghiệp bởi vì nguồn cung cấp gỗ dồi dào dẫn đến việc họ chỉ bám vào sát từ than củi
