Read the text about the origins of paper making. In each pair of sentences below, decide which one is the reason and which one is the consequence according to the text.

For many years throughout the Western world, paper was only made from discarded rags and clothing. Cotton and linen fibres produced a fine, strong paper, and the use of other plant fibres for papermaking was forgotten during the Dark Ages. However, paper was always a rare and valuable product due to the constant shortage of used cloth. The first paper mill in America, established outside of Philadelphia, Pennsylvania, in 1680, also used old rags to produce paper. By 1802, there were nearly 200 such mills in the United States.

During the mid-1800s, European papermakers rediscovered the use of tree fibres for papermaking. Also during this time, various types of technology were developed in Europe and America for breaking down wood and producing paper. Wood was in permanent access, and the use of wood rather than rags made it much cheaper and easier to make paper. This was the beginning of the mass-produced paper industry: an industry that played an important part in the development of our country and the world, and still does!
