30 Soal & Kunci Jawaban UTS/UAS Bahasa Inggris Kelas 11 SMA/SMK: Tsunami Happens Because?

Paper products that can be recycled include cardboard containers, wrapping paper, and office paper. The most commonly recycled paper product is newsprint. In newspaper recycling, old newspapers are collected and searched for contaminants such as plastic bags and aluminum foil. The paper goes to a processing plant where it is mixed with hot water and turned into pulp in a machine that works much like a big kitchen blender.

The pulp is screened and filtered to remove smaller contaminants. The pulp then goes to a large vat where the ink separates from the paper fibers and floats to the surface. The ink is skimmed off, dried, and reused as ink or burned as boiler fuel. The cleaned pulp is mixed with new wood fibers to be made into paper again.

Experts estimate the average office worker generates about 5 kg of wastepaper per month. Every ton of paper that is recycled saves about 1.4 cu m (about 50 cu ft) of landfill space. One ton of recycled paper saves 17 pulpwood trees (trees used to produce paper).

This Text is for question 9 to 108
All planes need air to presure under their wings to stay up in the air. As they move forward. The higher air pressure underneath their wings pushes them upward and gives them lift. The smooth, streamlined shape of the plane allows the air to flows easily over its surface. This helps to reduce the drag caused by the air pushing against the plane and allows it to move rapidly through the air. Planes move forward using engines. This movement is called thrust. Moving forward Keeps a stream of moving air passing over the wings. If the engines fail, theplanes will begin to descend very quickly. The air above the wing moves faster, so it is at a lower pressure than the air under the wing. The air under the wing moves more slowly and is slightly squashed, so it is at a higher pressure than the air above the wing.

9. What does the text describe?

A. How the wings of a plane work
B. How the plane moves forward
C. How the plane is made
D. The engine of a plane
