PAPER 2

SECTION A

[25 marks]

You are advised to spend about 50 minutes on this section.

Questions 1 25

For each of the questions in this section, blacken the answerA, B, C orD in the Answer

Sheets provided.

Question 1 2

Read the text below carefully and answer the questions that follow.

In Kuala Lumpur, we experience the haze almost yearly. During this time, our

visibility is reduced and the atmosphere has a hazy or opalescent appearance. What

causes the haze? It is a condition caused by tiny particles suspended in the

atmosphere which absorb sunlight. It mostly happens in urban or industrial areas due

to large quantities of pollutants emitted into the atmosphere. Most of the particles aredue to the open burning, land clearing, exhaust fumes and combustion of fossil fuels

in industries.

1. The haze is caused by the following reasons EXCEPTA. emissions from vehicles C. lack of sunlight

B. burning of garbage D. clearing of land

2. The haze is mainly concentrated in industrial areas because

A. these areas produce fossil fuels

B. factories produce a large amount of pollutants

C. there are many particles which absorb sunlight

Question 3 4

Rates of breast cancer among Asian women, who consume more soy protein onaverage than Americans do, are much lower than they are for women in the united

states. Scientists have hypothesized that plant estrogens called isoflavones provide this

protection by reducing ovarian hormone levels. If so, some researchers have reasoned

they could also impair fertility. The results of a new experiment on monkeys recently

however indicate that a high-soy diet does not reduce their fertility rate.

3. The phrase Scientist have hypothesized suggests that the scientists are ___________

about the effect of soy protein on breast cancer.A. sure C. confused

B. unsure D. confident

4. What does the word impair mean in the passage?

A. Improve C. Destroy

B. Reduce D. Increase

Question 6

There are about 89 000 species of monocotyledons and 170 000 species of

dicotyledons. Almost all monocots are herbaceous plants with soft, non-woody stems.

D. There are more species of dicots than monocots in the plant world.

Question 7

Researchers are now developing techniques of checking isotopes of oxygen and

hydrogen in the hair to help police solve crimes. Water in different regions of the world

produces subtly different isotopic signatures. By checking a suspects hair, it may bepossible in future for police to determine whether a suspect has been honest about

his/her whereabouts.

7. The isotopes of oxygen and hydrogen in the hair indicate

A. where a suspect has been living.

B. if a suspect is guilty or innocent.C. how a murder victim died.

C. It is slightly similar.

D. It is similar in two but different in the other.

Question 10

When you breathe in, air is sucked through the nose or mouth down the windpipe.

This branches into two main bronchi; one to each lung. In turn, the bronchi branch

into smaller tubes called bronchioles. Each bronchiole ends in an alveoli which

absorbs oxygen into the blood. There are millions of alveoli, making the total surface

area of the lungs very large.

10. From the text, which of these options show the correct sequence for the passage of

air?

A. Nose/mouth

lungs

trachea

bronchioles

alveoli

bloodB. Nose/mouth trachea bronchi bronchioles alveoli blood

C. Nose/mouth bronchi lungs trachea alveoli blood

D. Nose/mouth trachea bronchioles bronchi alveoli blood

Study the short notes below and then answer the questions that follow.

Meteors are interstellar debris of different sizes, floating or moving in space. When

the number of meteors moving together is large, it is called a meteor shower. Satellites

that are in the way of a meteor shower are sometimes badly damaged.

NASA has a new way of protecting satellites from meteor showers: by listening totelevision but not for the weather report. Rather, NASA is testing a system called

forward scatter radar that detects the interference of oncoming meteors with TV

signals from distant stations. The challenge is to accurately count the number of

meteors detected.

11. A meteor shower can cause extensive damage to a satellite. Thus, it can be inferred

that meteors can consists of

A. small stones C. big rocksB. coarse sand D. dust

12. NASA can predict oncoming meteor showers byA. detecting the interference with TV signals

B. counting the number of meteors in the sky

C. scattering the radar on the orbiting satellites

Question 13

Organisms are classified into five kingdoms of life. These kingdoms are known as

Monera, Protoctista, Fungi, Plantae, and Animalia. They are placed into these

categories based on similarities or common characteristics. Some of the characteristics

that are used to determine placement are cell type, metabolism, and reproduction.

13. Organisms are placed into categories based onA. common colour

B. common characteristicsC. Ability to absorb water

D. Dependency on sunlight

Question 14

The brainstem is comprised of the midbrain and the hindbrain. It resembles the stem of

a branch. The midbrain is the upper part of the branch that is connected to the

forebrain. It sends and receives information. When data is gathered from our senses,

such as sight and hearing, it is sent to this area and then directed to the forebrain.

14. Data gathered from our senses is directed to

A. The midbrainB. The hindbrain

C. The forebrain

D. The stem

Questions 15 16


A single muscle fiber is a cyclindrical, elongated cell. Muscle cells can differ in

length. The sartorious muscle contains single fibers that are at least 30 cm long.

Each fiber is surrounded by a thin layer of connective tissue called endomysium.Collectively, thousands of muscle fibers are wrapped by a thin layer of connective

tissue called the perimysium to form a muscle bundle. Groups of muscle bundles

that join into a tendon at each end are called muscle groups, or simply muscles.

15. A muscle bundle consists ofA. One single cylindrical elongated cell

B. Many muscle fibers wrapped by a connective tissue

C. Groups of muscles that join at a tendon on two endsD. The perimysium

Questions 22 23


Strokes are caused by a lack of blood flow and insufficient oxygen to the brain that

causes the death of brain tissue. There are two types of strokes. An ischemic stroke

occurs when the blood supply is cut off to a part of the brain due to the blockage of ablood vessel by a blood clot or arteriosclerosis. The hemorrhagic stroke is caused by

the bursting of a blood vessel that prevents normal flow and causes blood to leak into

and destroy an area of the brain.

22. When blood is cut off to the brain due to a blockage of a blood vessel, what hasoccurred?

A. Hemorrhagic stroke C. Arteriosclerosis

B. Heart attack D. Ischemic stroke
