Explanation is a text which tells processes relating to forming of natural, social, scientific and cultural phenomena. Explanation text is to say ‘why’ and ‘how’ of the forming of the phenomena. It is often found in science, geography and history text books.
B. Generic Structure of Explanation Text
– General statement
General statement; stating the phenomenon issues which are to be explained.
– Sequenced of explanation
Sequenced explanation; stating a series of steps which explain the phenomena.
C. Purpose of Explanation Text
– Explanation is a text which tells processes relating to forming of natural, social, scientific, and cultural phenomena.
– To explain how or why something happens.
According to Mark Anderson and Kathy Anderson (1997: 82) says that the explanation text type is often used to tell how and why thing (phenomena) occur in nature.
D. Characteristics of Explanation Text
- Derived from the author's questions regarding the 'why' and 'how' of an existing phenomenon
- Lifted from the phenomenon, the focus of the material is not on the object or person, but on events or events that occur to the person or object.
- Using Simple Present Tense
- Using action verbs
- Using passive voice
- Using noun phrases
- Using adverbial phrases

Question and answer about Explanation Text
Biodiesel is a clean burning substitute for petroleum based diesel fuel. Biodiesel is made of vegetable oil.
To make or manufacture Biodiesel, you must first start with raw materials. The raw materials needed in the production of Biodiesel are a small amount of methanol and a ready supply of vegetable product. One of the most common vegetables used in the production of Biodiesel is corn, although depending on the geographic location of the manufacturing facility many other plants are used as well (rapeseed, soybeans, flaxseed, etc.). The first step is to use the raw vegetable product to make vegetable oil. Vegetable oil by itself will not be what you need to power a car, from here it has to be processed into Biodiesel.
The process for converting vegetable oil into Biodiesel is sometimes called ester interchange. To complete this process the vegetable oil has to be combined with a smaller amount of methanol and then put in the presence of a small quantity of an alkaline catalyst (for example, 5% to 1% sodium hydroxide). Vegetable oil is made up of so-called triglycerides, which is a compound of the trivalent alcohol glycerin with three fatty acids. The goal of ester interchange is to separate the glycerin molecule from the three fatty acids and replace it with three methanol molecules. This process then yields roughly 90% Biodiesel and 10% of a glycerin byproduct. The glycerin byproduct can be used in a number of other chemical processes for different industries.

There are four main kinds of taste: sweet, sour, salty, and bitter. All other tastes are just mixtures of two or more of these main types.
The surface of the tongue has more than fifteen thousand taste-buds (or cells). These are connected to the brain by special nerves which send the so-called ‘tastes messages.
When the tongue comes into contact with food of any kind, the taste-buds will pick up the taste. The nerves then send a message to the brain. This will make us aware of the taste. All this happens in just a few seconds.
There are four kinds of taste-buds, each of which is sensitive to only a particular taste. These four groups are located in different parts of the tongue.
The taste-buds for salty and sweet tastes are found round the tip of the tongue and along its sides. Sour tastes can be picked up only at the sides of the tongue. The taste-buds of the bitter taste are found at the innermost edge of the tongue. There are taste-buds at the centre of the tongue.
The senses of smell and sight can affect taste. The good smell of food increases its taste. Similarly, attractive colours can make food appear tastier and more delicious. If food does not smell good or is dull-coloured, it will look tasty and may not taste good at all.
Very hot or cold sensations can make the taste-buds insensitive. Food that is too hot or too cold, when placed in the mouth, will have no tastes at all.

C. the taste of the food increases
D. the taste-buds will be sensitive
E. the taste-buds will be very, responsive
B. the four main kinds of taste
C. the taste-buds in the tongue
D. the senses of smell and sight
E. the taste-buds round the tip of the tongue
The caterpillar makes its cocoons using these strands. The threads on the outside of the cocoon are rough, while those inside are soft and smooth.
Some fully-spun cocoons are heated. This kills the pupa inside. The cocoons are then put into hot water to loosen the fine threads. Finally, these threads are reeled off the cocoons.
The length of unbroken thread produced by a single cocoon measures about one-and-a-half kilometers. Being twisted together several of these threads make single woven materials.
