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 over900,000 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 famineand 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 arenatures 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 separateforms 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 brains

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 andchoose 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 awave 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 30metres or more. These giant waves are called tsunamis.

Chalk is a mineral usually found on the seabed and seaside cliffs. Thismineral is formed from very fine grains of calcium carbonate that haveseparated from seawater and settled to become white, muddy sediment onthe sea floor. Over millions of years, the sediment hardened to form chalk.

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, theybecome active again. Unlike cellularorganisms, viruses do not repair, grow, or respond to stimuli. Viruses canreproduce only within a living cell, called a host cell. During reproduction,many viruses kill the host cell. However, cellular organisms do notnecessarily 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 materialsare 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.

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 patients

A tensions

B migraines

C body circulation

D circulatory system

In most mammal species, females carry their young in the uterus duringthe development, nourishing them by a placenta, and give birth to liveyoung. The placenta is a specialised organ within the womb of themother that brings the bloodstream of the foetus into close contact withthe blood stream of the mother. The placenta is attached to the umbilical

cord. It serves as the provisional lungs, intestines and kidneys of theembryo, without ever mixing maternal and foetal blood. Food, water, andoxygen can pass across from mother to child, and wastes can pass overto the mothers blood and be carried away.

Gingko may be effective in treating ailments associated with decreasedblood flow to the brain. The circulatory system in the body can beboosted by gingko as well and it is a good option in the treatment ofcirculation headaches. Linden relieves tensions and sinus headaches,helping to calm the mind. Also, linden flowers improve the overallfunctioning of the circulatory system and researchers believe it could

cure migraine as well.

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 Dollys birth in 1997, scientists have successfully cloned a widevariety of farm animals and cloning procedures have become increasinglyefficient. Only a small fraction of the transplanted embryos survive to term,however, with most dying late in pregnancy. Those that survive to be bornusually die soon thereafter. Many become oversized, a condition known aslarge offspring syndrome. The few cloned offspring that reach childhoodface an uncertain future, as their development into adults tends to gounexpectedly haywire. Almost none survive to live a normal life span.

Friction is a type of force that opposes the motion of an object when theobject is in contact with another object or surface. Friction results from twosurfaces rubbing against each other or moving relative to one another. Itcan 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 thatare in contact and the force pushing them together. This force is usuallyrelated to the weight of the object or objects.

Hardware includes all the components used to make a computer. Theentire computer frame that you see, regardless if the computer is switched-off, is the hardware. Hardware is usually made of metal, plastic or fibre. Itconsists 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 frequentlythroughout the day, our exposure to these sources is constant. Tap waterhas been found to be contaminated with parasitic organisms. Manyrestaurants have less than sanitary conditions ranging from foodpreparation and storage to the utensils and servers hands.

People with short-sightedness (myopia) are not able to see objects that arefar away. This is because light rays focus in front of the retina, a result fromthe fact that the eye is not able to focus light rays further back, despitemaximum flattening of its lens. Short-sightedness mainly affects a personsability 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 arebulimic. People with bulimia are also obsessed with their body, weight gainand how they appear to others. Unlike those with anorexia, people withbulimia are often not noticed because their weight varies slightly from theirnormal weight. At the same time, treatment is more effective for bulimiarather than anorexia.

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 elderlys 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 mainframecomputers and minicomputers. Mainframe computers are physically thelargest computers you will maintain. Their ruggedness makes them more

suited than microcomputers and minicomputers to handle the mechanicalshock and vibration, salt spray, temperature and humidity.

The term presbyopia means old eye and is a vision condition involving theloss of the eyes ability to focus on both near and far objects. It is acondition that occurs as part of normal aging, because when a person getsolder, ones eye lenses become harder and less elastic. The muscles inthe ciliary body also lose their ability to contract and relax. Presbyopiaoccurs gradually over a number of years and is usually noticeable by age40-45.Presbyopia is corrected by wearing glasses with bifocal lenses tosee near and far objects clearly.
