[Time suggested : 30 minutes]
Question 1
Read the following text and complete the given task.
(Adapted from: Just English Vol 2. Issue 3)
Insects first appeared over 400 million years ago. Today, scientists have recorded over
900,000 species of insects, more than all other plants and animals. The typical insect
structure, comprising a head, thorax and abdomen with six legs and a set of wings, is
particularly mobile and robust.
As a general rule insects get a very bad press. Over the centuries, insects have been
responsible for spreading terrible diseases such as malaria, sleeping sickness and plague.
Insects such as locusts have also consumed crops before they are harvested, causing famine
and starvation. However, despite such damning evidence, perhaps it is now time to restore
the balance and consider life without insects.
Insects are primary food source for the majority of reptiles, amphibians and birds.
Deprived of their food source, such animals would quickly die out. Without insects,
flowering plants would not be pollinated and would fail to reproduce. In addition, insects are
nature’s most effective recyclers. Without insects to recycle the nutrients in dead animals
and plants, the earth would swiftly cease to contain essential nutrient. Eventually, if there
were no insects, only wind-pollinated plants would survive and the land would be inhabited
by only a sparse and meagre animal life.
There are a number of explanations for the amazing success of insects. Insects are
capable of changing form, or metamorphosing, and consequently are able to exploit separate
forms of food and habitat whether on land or in the water.

Question 2
Read the following text and complete the given task.
When scientists first examined the human brain, they found it to be divided into two
hemispheres, which are nearly identical in appearance, mirroring each other just as the two
sides of the body do. When Roger Sperry examined patients whose connection between the
two hemispheres - the corpus callosum - was severed, he found that the two sides of brain
seemed to have different functions.
Many investigators have studied the differences between the functions of the two
hemispheres and have found their relationship to be quite complex. Unfortunately, however,
most people have tended to over-generalise. The left brain is supposed to be logical, rational
and analytical, whereas the right brain is supposed to be creative and emotional. The brain’s
hemispheres are not so simplistically split into two neat divisions. In fact, both hemispheres
participate in almost all our mental activities.
Both hemispheres are in operation when we reason. The left hemisphere is dominant in
recognising abstract differences. The right hemisphere tends to recognise sameness.
The two hemispheres act as partners in language and communication. It appears that the
left hemisphere is dominant when it comes to understanding grammar and syntax, but when
it comes to interpreting emotions in communication, the right brain excels. Whenever we use
language, both hemispheres process the information.
The brain is not totally divided about music. Many people assume that music is
mediated solely in the right brain. That is not so. It is true that the right brain recognises
chords and melodies and seems to mediate pure and slow tones. The left hemisphere is also
involved in music. Fast music, such as bluegrass, requires the brain to make judgments about
sequencing and rhythm and for this the left hemisphere lends its services.
Both hemispheres are involved in our mental activities which are in constant
communication to make sense out of life.

Questions 1 – 25 are based on the given stimuli. Study the information carefully and
choose the best answer.
1. Tsunamis are caused by
A shallow waters near a coast
B giant waves of 30 metres or more
C wave movements in the open ocean
D earthquakes under the ocean floor
2. The sediment is made up of
A tiny pieces of chalk
B calcium carbonate grains
C seawater and chalk grains
D mud and calcium carbonate
When an earthquake takes place beneath the sea bed, it may produce a wave in the sea. In the open ocean, the wave may hardly be noticed. But if it reaches shallow water near a coast, the wave may rise to heights of 30 metres or more. These giant waves are called tsunamis.
Chalk is a mineral usually found on the seabed and seaside cliffs. This mineral is formed from very fine grains of calcium carbonate that have separated from seawater and settled to become white, muddy sediment on the sea floor. Over millions of years, the sediment hardened to form chalk.

A viruses
B crystals
C solutions
D organisms
4. Both viruses and cellular organisms
A contain protein and nucleic acid.
B need a living cell to multiply.
C can be turned into crystals.
D can respond to stimuli.
Viruses exhibit some but not all the characteristics of living things. Viruses, like all living cellular organisms, contain protein and nucleic acid. However, unlike cellular organisms, viruses can be solidified into crystals. But when placed in solutions, they become active again. Unlike cellular organisms, viruses do not repair, grow, or respond to stimuli. Viruses can reproduce only within a living cell, called a host cell. During reproduction, many viruses kill the host cell. However, cellular organisms do not necessarily need a host to reproduce.

Wastewater treatment is essential in providing clean and safe water
consumption. There are three basic phases of wastewater treatment in a
treatment plant: primary, secondary and tertiary. In the primary phase,
the first stage is screening where vertical metal bars remove bulky debris
or objects. Next, it is passed through a grinder where organic materials
are reduced in size. In a grit chamber, inorganic matters are removed.
Then, in a sedimentation tank, organic materials are drawn off for
disposal. Then it is further treated in a closed tank in a process called
digestion. The final stage is drying where the digested sludge is dried
and converted into fertiliser.

6. A placenta within the womb of female mammals serves as
A the potential internal organs for the foetus
B the bloodstream for the foetus and the mother
C a passage for the supply of nourishment for the foetus
D a medium for close contact of the foetus and the mother
7. Both gingko and linden can cure headaches because they work on the patient’s
A tensions
B migraines
C body circulation
D circulatory system
In most mammal species, females carry their young in the uterus during the development, nourishing them by a placenta, and give birth to live young. The placenta is a specialised organ within the womb of the mother that brings the bloodstream of the foetus into close contact with the blood stream of the mother. The placenta is attached to the umbilical cord. It serves as the provisional lungs, intestines and kidneys of the embryo, without ever mixing maternal and foetal blood. Food, water, and oxygen can pass across from mother to child, and wastes can pass over to the mother’s blood and be carried away.
Gingko may be effective in treating ailments associated with decreased blood flow to the brain. The circulatory system in the body can be boosted by gingko as well and it is a good option in the treatment of circulation headaches. Linden relieves tensions and sinus headaches, helping to calm the mind. Also, linden flowers improve the overall functioning of the circulatory system and researchers believe it could cure migraine as well.

8. Cloned farm animals
A will all become oversized
B are unable to live an expected life span
C develop normally as they reach adulthood
D have largely been successful to survive to term
9. In order for objects to be moved
A their weight has to be the same.
B the surfaces must be in contact with each other.
C enough friction has to be forced upon the objects.
D force has to be applied to oppose the friction caused.
Since Dolly’s birth in 1997, scientists have successfully cloned a wide variety of farm animals and cloning procedures have become increasingly efficient. Only a small fraction of the transplanted embryos survive to term, however, with most dying late in pregnancy. Those that survive to be born usually die soon thereafter. Many become oversized, a condition known as large offspring syndrome. The few cloned offspring that reach childhood face an uncertain future, as their development into adults tends to go unexpectedly haywire. Almost none survive to live a normal life span.
Friction is a type of force that opposes the motion of an object when the object is in contact with another object or surface. Friction results from two surfaces rubbing against each other or moving relative to one another. It can hinder the motion of an object or prevent an object from moving at all. The strength of frictional force depends on the nature of the surfaces that are in contact and the force pushing them together. This force is usually related to the weight of the object or objects.

Scientists have mapped the genetic code of honey bees, uncovering clues
about their complex social behaviour and their heightened sense of smell.
The honey bees or Apis mellifera evolve more slowly than other insects
and have more genes related to smell. Even though the honey bees have
tiny brains, they display mental prowess and can discern a flower’s shape,
colour and scent quite skilfully.

A mainly made of metal and plastic
B the physical parts of a computer
C a set of keyboard, monitor, mouse, printer and disk
D the parts of a computer that can be seen only when it is switched on
13. People are easily exposed to contamination because
A people consume food and water many times a day
B sanitary measures are followed in restaurants
C food is left exposed all the time
D all water is contaminated
Hardware includes all the components used to make a computer. The entire computer frame that you see, regardless if the computer is switched-off, is the hardware. Hardware is usually made of metal, plastic or fibre. It consists of all the parts of the computer which you can actually touch, including the keyboard, monitor, mouse, printer and disk.
Food and water are the most common sources of parasite transmission. Since most of us eat three times a day and drink water frequently throughout the day, our exposure to these sources is constant. Tap water has been found to be contaminated with parasitic organisms. Many restaurants have less than sanitary conditions ranging from food preparation and storage to the utensils and servers’ hands.

Natural fibres must be cleaned or washed before being spun (twisted) into long threads of yarn. Man-made fibres are also spun: cotton polyester is a mix of natural and synthetic fibres, for example. The yarn is then woven into cloth. Not all fabrics are made by weaving. Knitting is a different process that entwines loops of yarns in a wax.

Kinetic energy is energy in motion. Anything that is moving or changing has kinetic energy. Potential energy is stored energy. Something has potential energy when it is not moving, but it is about to move. Mechanical energy is produced by objects or machines changing their positions. Chemical energy is released when substances are broken down.
Two different blood types cannot be mixed together as the blood cells may clump together which can cause fatality. This is why blood types must be matched before blood transfusion can take place.
• A person with Type A blood can donate blood to a person with Type A or Type AB
• A person with Type B blood can donate blood to a person with Type B or Type AB
• A person with Type AB blood can donate blood to a person with Type AB only
• A person with Type O blood can donate blood to anyone.

People with short-sightedness (myopia) are not able to see objects that are far away. This is because light rays focus in front of the retina, a result from the fact that the eye is not able to focus light rays further back, despite maximum flattening of its lens. Short-sightedness mainly affects a person’s ability to look at distant objects where the light rays come straight or parallel into the eyes.
People with bulimia often go on eating spree (binge) and secretly vomit, losing the calories acquired. It is estimated that about 3% of females are bulimic. People with bulimia are also obsessed with their body, weight gain and how they appear to others. Unlike those with anorexia, people with bulimia are often not noticed because their weight varies slightly from their normal weight. At the same time, treatment is more effective for bulimia rather than anorexia.

The emergents consist of the tops of the tallest trees, which are much higher than the average canopy height (ranging up to 270 feet or 81 m). It houses many birds and insects while the forest floor is teeming with animal life, especially insects and arachnids plus large animals. The understory is a dark, cool environment that is under the leaves but over the ground. Most of the understory of a rainforest has so little light that plant growth is limited. On the other hand, the canopy; the upper parts of most of the trees, is full of life. Insects, arachnids, many birds and some mammals thrive in this area.

D movable
24. From the text, we can conclude that
A all senior citizens experience this problem
B old people tend to suffer from presbyopia
C presbyopia can be overcome by wearing sunglasses
D the elderly’s eye lenses lose the ability to contract and relax
Microcomputers or personal computers are small, lightweight and portable. Some of them are more powerful than some of the older, larger mainframe computers and minicomputers. Mainframe computers are physically the largest computers you will maintain. Their ruggedness makes them more suited than microcomputers and minicomputers to handle the mechanical shock and vibration, salt spray, temperature and humidity.
The term presbyopia means ‘old eye’ and is a vision condition involving the loss of the eye’s ability to focus on both near and far objects. It is a condition that occurs as part of normal aging, because when a person gets older, one’s eye lenses become harder and less elastic. The muscles in the ciliary body also lose their ability to contract and relax. Presbyopia occurs gradually over a number of years and is usually noticeable by age 40-45.Presbyopia is corrected by wearing glasses with bifocal lenses to see near and far objects clearly.
