Reading Passage 1

You should spend about 20 minutes on QUESTIONS 1-13 which are based on Reading Passage 1

below.

William Henry Perkin

The man who invented synthetic dyes

William Henry Perkin was born on March 12, 1838, in London, England. As a boy, Perkin's

curiosity prompted early interests in the arts, sciences, photography, and engineering. But it was a

chance stumbling upon a run-down, yet functional, laboratory in his late grandfather's home that

solidified the young man's enthusiasm for chemistry.

As a student at the City of London School, Perkin became immersed in the study of chemistry. His

talent and devotion to the subject were perceived by his teacher, Thomas Hall, who encouraged

him to attend a series of lectures given by the eminent scientist Michael Faraday at the Royal

Institution. Those speeches fired the young chemist's enthusiasm further, and he later went on to

attend the Royal College of Chemistry, which he succeeded in entering in 1853, at the age of 15.

At the time of Perkin's enrolment, the Royal College of Chemistry was headed by the noted

German chemist August Wilhelm Hofmann. Perkin's scientific gifts soon caught Hofmann's

attention and within two years, he became Hofmann's youngest assistant. Not long after that,

Perkin made the scientific breakthrough that would bring him both fame and fortune.

At the time, quinine was the only viable medical treatment for malaria. The drug is derived from

the bark of the cinchona tree, native to South America, and by 1856 demand for the drug was

surpassing the available supply. Thus, when Hofmann made some passing comments about the

desirability of a synthetic substitute for quinine, it was unsurprising that his star pupil was moved

to take up the challenge.

During his vacation in 1856, Perkin spent his time in the laboratory on the top floor of his family's

house. He was attempting to manufacture quinine from aniline, an inexpensive and readily

available coal tar waste product. Despite his best efforts, however, he did not end up with quinine.

Instead, he produced a mysterious dark sludge. Luckily, Perkin's scientific training and nature

prompted him to investigate the substance further. Incorporating potassium dichromate and

alcohol into the aniline at various stages of the experimental process, he finally produced a deep

purple solution. And, proving the truth of the famous scientist Louis Pasteur's words 'chance

favours only theprepared mind’. Perkin saw the potential of his unexpected find.

Historically, textile dyes were made from such natural sources as plants and animal excretions.

Some of these, such as the glandular mucus of snails, were difficult to obtain and outrageously

expensive. Indeed, the purple colour extracted from a snail was once so costly that in society at the

time only the rich could afford it. Further, natural dyes tended to be muddy in hue and fade quickly.

It was against this backdrop that Perkin's discovery was made.

Perkin quickly grasped that his purple solution could be used to colour fabric, thus making it the

world's first synthetic dye. Realising the importance of this breakthrough, he lost no time in

patenting it. but perhaps the most fascinating of all Perkin's reactions to his find was his nearly

instant recognition that the new dye had commercial possibilities.

Perkin originally named his dye Tyrian Purple, but it later became commonly known as mauve

(from the French for the plant used to make the colour violet). He asked advice of Scottish dye

works owner Robert Pullar, who assured him that manufacturing the dye would be well worth it if

the colour remained fast (i.e. would not fade) and the cost was relatively low. So, over the fierce

objections of his mentor Hofmann, he left college to give birth to the modern chemical industry.

With the help of his father and brother, Perkin set up a factory not far from London. Utilising the

cheap and plentiful coal tar that was an almost unlimited byproduct of London's gas street lighting,

the dye works began producing the world's first synthetically dyed material in 1857. The company

received a commercial boost from the Empress Eugenie of France, when she decided the new

colour flattered her. Very soon, mauve was the necessary shade for all the fashionable ladies in

that country. Not to be outdone, England's Queen Victoria also appeared in public wearing a

mauve gown, thus making it all the rage in England as well. The dye was bold and fast, and the

public clamoured for more. Perkin went back to the drawing board.

Although Perkin's fame was achieved and fortune assured by his first discovery, the chemist

continued his research. Among other dyes he developed and introduced were aniline red (1859)

and aniline black (1863) and, in the late 1860s, Perkin's green. It is important to note that Perkin's

synthetic dye discoveries had outcomes far beyond the merely decorative. The dyes also became

vital to medical research in many ways. For instance, they were used to slain previously invisible

microbes and bacteria, allowing researchers to identify such bacilli as tuberculosis, cholera, and

anthrax. Artificial dyes continue to play a crucial role today. And, in what would have been

particularly pleasing to Perkin, their current use is in the search for a vaccine against malaria.

Reading Passage 2

You should spend about 20 minutes on QUESTIONS 14-26 which are based on Reading Passage 2

below.

Is there anybody out there?

The search for extra-terrestrial intelligences

The question of whether we are alone in the Universe has haunted humanity for centuries, but we

may now stand poised on the brink of the answer to that question, as we search for radio signals

from other intelligent; civilisations. This search, often known by the acronym SETI (search for

extra-terrestrial intelligence), is a difficult one. Although groups around the world have been

searching intermittently for three decades, it is only now that we have reached the level of

technology where we can make a determined attempt to search all nearby stars for any sign of life.

A The primary reason for the search is basic curiosity - the same curiosity about the natural

world that drives all pure science. We want to know whether we are alone in the Universe. We

want to know whether life evolves naturally if given the right conditions, or whether there is

something very special about the Earth to have fostered the variety of life forms that we see

around us on the planet. The simple detection of a radio signal will be sufficient to answer this

most basic of all questions. In this sense, SETI is another cog in the machinery of pure science

which is continually pushing out the horizon of our knowledge. However, there are other reasons

for being interested in whether life exists elsewhere. For example, we have had civilisation on

Earth for perhaps only a few thousand years, and the threats of nuclear war and pollution over the

last few decades have told us that our survival may be tenuous. Will we last another two thousand

years or will we wipe ourselves out? Since the lifetime of a planet like ours is several billion years,

we can expect that, if other civilisations do survive in our galaxy, their ages will range from zero

to several billion years. Thus any other civilisation that we hear from is likely to be far older, on

average, than ourselves. The mere existence of such a civilisation will tell us that long-term

survival is possible, and gives us some cause for optimism. It is even possible that the older

civilisation may pass on the benefits of their experience in dealing with threats to survival such as

nuclear war and global pollution, and other threats that we haven't yet discovered.

B In discussing whether we are alone, most SETI scientists adopt two ground rules. First, UFOs

(Unidentified Flying Objects) are generally ignored since most scientists don’t consider the

evidence for them to be strong enough to bear serious consideration (although it is also important

to keep an open mind in case any really convincing evidence emerges in the future). Second, we

make a very conservative assumption that we are looking for a life form that is pretty well like us,

since if it differs radically from us we may well not recognise it as a life form, quite apart from

whether we are able to communicate with it. In other words, the life form we are looking for may

well have two green heads and seven fingers, but it will nevertheless resemble us in that it should

communicate with its fellows, be interested in the Universe, live on a planet orbiting a star like our

Sun. And perhaps most restrictively, have a chemistry, like us, based on carbon and water.

C Even when we make these assumptions, our understanding of other life forms is still severely

limited. We do not even know, for example, how many stars have planets, and we certain^ do not

know how likely it is that life will arise naturally, given the right conditions. However, when we

look at the 100 billion stars in our galaxy (the Milky Way), and 100 billion galaxies in the

observable Universe, it seems inconceivable that at least one of these planets does not have a life

form on it; in fact, the best educated guess we can make, using the little that we do know about the

conditions for carbon-based life, leads us to estimate that perhaps one in 100,000 stars might have

a life-bearing planet orbiting it. That means that our nearest neighbours are perhaps 100 light years

away, which is almost next door in astronomical terms.

D An alien civilisation could choose many different ways of sending information across the

galaxy, but many of these either require too much energy, or else are severely attenuated while

traversing the vast distances across the galaxy. It turns out that, for a given amount of transmitted

power, radio waves in the frequency range 1000 to 3000 MHz travel the greatest distance, and so

all searches to date have concentrated on looking for radio waves in this frequency range. So far

there have been a number of searches by various groups around the world, including Australian

searches using the radio telescope at Parkes, New South Wales. Until now there have not been any

detections from the few hundred stars which have been searched. The scale of the searches has

been increased dramatically since 1992, when the US Congress voted NASA $10 million per year

for ten years to conduct a thorough search for extra-terrestrial life. Much of the money in this

project is being spent on developing the special hardware needed to search many frequencies at

once. The project has two parts. One part is a targeted search using the world's largest radio

telescopes, the American-operated telescope in Arecibo, Puerto Rico and the French telescope in

Nancy in France. This part of the project is searching the nearest 1000 likely stars with high

sensitivity for signals in the frequency range 1000 to 3000 MHz. The other part of the project is an

undirected search which is monitoring all of space with a lower sensitivity, using the smaller

antennas of NASA's Deep Space Network.

E There is considerable debate over how we should react if we detect a signal from an alien

civilisation. Everybody agrees that we should not reply immediately. Quite apart from the

impracticality of sending a reply over such large distances at short notice, it raises a host of ethical

questions that would have to be addressed by the global community before any reply could be sent.

Would the human race face the culture shock if faced with 8 superior and much older civilisation?

Luckily, there is no urgency about this. The stars being searched are hundreds of light years away,

so it takes hundreds of years for their signal to reach us, and a further few hundred years for our

reply to reach them. It's not important, then, if there's a delay of a few years, or decades, while the

human race debates the question of whether to reply, and perhaps carefully drafts a reply.
