LATIHAN SOAL EXPLANATION TEXT

Recycling is a collection, processing, and reuse of materials that would otherwise be thrown away. Materials ranging from precious metals to broken glass, from old newspapers to plastic spoons, can be recycled. The recycling process reclaims the original material and uses it in new products.

In general, using recycled materials to make new products costs less and requires less energy than using new materials. Recycling can also reduce pollution, either by reducing the demand for high-pollution alternatives or by minimizing the amount of pollution produced during the manufacturing process.

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 fl oats 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).

Which of the following is NOT the benefit of recycling?

• It costs much money for the process of recycling

• It costs less to make new products

• It requires less energy

• It can reduce pollution

• It reduces the demand for high-pollution alternatives

We can make use of the ink after being separated from the paper fibres by doing the followings, EXCEPT....

• Skim it off

• Dry it

• Reuse as ink

• Burn as boiler fuel

• Mix it with the pulp

Human body is made up of countless millions of cells. Food is needed to build up new cells and replace the worn out cells. However, the food that we take must be changed into substances that can be carried in the blood to the places where they are needed. This process is called digestion.

The first digestive process takes place in the mouth. The food we eat is broken up into small pieces by the action of teeth, mixed with saliva, a juice secreted by glands in the mouth. Saliva contain digestive juices which moisten the food, so it can be swallowed easily.

From the mouth, food passes through the esophagus (the food passage) into stomach. Here, the food is

mixed with juices secreted by the cells in stomach for several hours. Then the food enters the small intestine. All time the muscular walls of the intestine are squeezing, mixing and moving the onwards.

In a few hours, the food changes into acids. These are soon absorbed by the villi (microscopic branch projections from the intestine walls) and passed into the bloodstream.

The purpose of the text is …..

• To explain the process involved in digestion

• To inform the readers about important part of human body

• To entertain or amuse the readers

• To persuade people that men have millions of cells

• To give a description about esophagus and villi

What is “digestion” mean?.....

• The process of replacing worn out cells

• The process of changing food into substances that can be carried in the blood

• The process of building up new cells

• The process of taking food into our mouth

• The process of providing energy for each cell
