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.

Today, almost all paper is made from wood pulp; however, some speciality papers are still produced using cotton and linen fibres (for printing things like money and maps). But what exactly is wood pulp? When wood is broken down, either mechanically or chemically, two main things are left: fibres (composed mostly of two kinds of cellulose) and lignin. The fibres are actually the remains of the tree's cells. They are small, about 1/8 of an inch in length and 1/150 of an inch in width (about 1/10 the thickness of a human hair). Lignin is the glue, or cement, that holds the fibres in place in the wood.

The papermaking process begins by washing, bleaching (to whiten or "brighten" if necessary), and beating (to soften) wood pulp. Starches, colours, and other chemicals added at this early stage create different types of paper. After mixing the pulp and chemicals with water, this "slush" moves into large papermaking machines.

Rolls of paper are the finished product. They are usually rewound and cut into smaller rolls or packs, then shipped to printers and manufacturing plants to become products. Throughout the papermaking process, tests ensure paper quality. If a roll of paper does not meet quality standards for the desired finished product, it is recycled back into the process.

Choose the correct option.

A.

Paper is still made from extra materials (besides wood).

There are paper goods with special requirements for materials (money, maps, etc.)

B.
