Passage 1 on pages 2 and 3
Pepper, the spice, comes from the berries of a plant that is a woody climbing vine. In the
botanical world, pepper belongs to a genus of plants called Piper. This genus was
created in 1753 by Carl Linnaeus, the Swedish botanist whose system for classifying
plants is still in use today. He placed seventeen species in the piper genus and probably
used the ancient Greek name for black pepper, Peperi, as the basis for the group.
Pepper isn't a fast-maturing plant. It takes several years for the branching woody vines
to mature, and during their growth the vines can reach up to thirty feet. The pepper
berries- which grow in clusters and dangle from the vines-are picked by hand when they
are ready for harvesting, which usually begins two or three years after the vine is first
planted. Black pepper is picked when the berries are still green, while white pepper is
picked later, when the berries have turned from green to red. Preparing the berries for
sale involves a lengthy process of drying, cleaning and sorting. Once the berries have
been dried, they are then referred to as peppercorns, and these are what are used in
food preparation around the world.
The pepper plant loves the warm, humid, rainy tropics, in a narrow band around the
equator. Pepper also requires well-drained soils, and its preferred habitat is forests.
Unshaded plants which are exposed too long to the sun will not yield many berries. The
colourful mixes of whole peppercorns seen in many markets today contain green and
black peppercorns. Although there are pink peppercorns, the ripest berries, these are
more fragile and are therefore more costly than other kinds. This is why there are few of
them in a peppercorn mix.
No one knows when the first human bit into a peppercorn and decided it would taste
good on a piece of meat or in a vegetable stew, but in the West it was the ancient
Romans who apparently first made pepper an essential part of their meals. Food was
only part of the reason for pepper's popularity; health played an equally important role.
In the Roman Empire, pepper was employed to relieve the pain that was a common
consequence of numerous medical conditions and complaints. If you showed signs of
a fever, it was common practice to be given a liquid that had some pepper in it.
The Romans were not the first to embrace pepper as a medicine. Belief in the spice's
considerable usefulness is reflected in India's ancient Ayurvedic system of medicine,
which is more than three thousand years old. In Sanskrit (a language of ancient India),
black pepper is known as maricha or marica, meaning an ability to get rid of poison,
which suggests it was used in patients for this purpose. Pepper was also believed by the
Indians to have other qualities as well. For example, physicians would frequently apply
pepper-based lotions to reduce the effects of decay in teeth, which made it an extremely
popular remedy.
In the Middle Ages (5th-15th centuries) black peppers renown made it a must-have item
for the European wealthy, who loved the spice. At that time, pepper was guarded by
servants in royal households and kept in the private wardrobes of the rich. It was
considered a privilege to cook with pepper and many of the recipes from the period
called for substantial quantities of pepper, which might be considered very unappetising
today. But for most people, pepper was too expensive. In the year 1439, a pound of
pepper was roughly equal to more than two days' pay in England. Meanwhile, pepper
could be exchanged for gold, and also became a form of payment for peoples work. In
some of the larger cities, it was even possible to use pepper as rent in some kinds of
accommodation. Employees in the pepper industry were not allowed to have pockets in
their jackets or trousers so that this valuable commodity would not be stolen.
The huge demand for pepper and the money it could bring encouraged people to risk
adventure on foreign oceans and in foreign lands, and it is within this context that the
story of pepper really begins.

                                    Australian parrots
                          and their adaptation to habitat change
A Parrots are found across the tropic and in all southern hemisphere continents except
Antarctica, but nowhere, do the display such a richness of diversity and form as in
Australia. One-sixth of the world's 345 parrot species are found there, and Australia has
long been renowned for the number and variety of its parrots.
B In the 16th century, the German cartographer Mercator made a world map that
included a place, somewhere near present-day Australia, that he named Terra
Psittacorum - the Land of Parrots - and the first European settles in Australia often
referred to the country as Parrot Land. In 1865, the celebrated British naturalist and
wildlife artist John Gould said: "No group of birds gives Australia so tropical and benign
an air as the numerous species of this great family by which it is tenanted.
C Parrots are descendants of an ancient line. Due to their great diversity, and since
most species inhabit Africa, Australia and South America, it seems almost certain that
parrots originated millions of years ago on the ancient southern continent of Gondwana,
before it broke up into the separate southern hemisphere continents we know today.
Much of Gondwana comprised vast rainforests intersected by huge slow-flowing rivers
and expansive lakes, but by eight million years ago, great changes were underway. The
centre of the continent of Australia had begun to dry out, and the rainforests that once
covered it gradually contracted to the continental margins, where, to a limited extent,
they still exist today.
D The creatures that remained in those shrinking rainforests had to adapt to the drier
conditions or face extinction. Reacting to these desperate circumstances, the parrot
family, typically found in jungles in other parts of the world, has populated some of
Australia's harshest environments. The parrots spread from ancestral forests through
eucalypt woodlands to colonies the central deserts of Australia, and as a consequence
they diversified into a wide range of species with adaptations that reflect the many
changes animals and plants had to make to survive in these areas.
E These evolutionary pressures helped mould keratin, the substance from which breaks
are made into a range of tools capable of gathering the new food types favored by
various species of parrot. The size of a parrot's short, blunt beak and the length of that
beak's do curved upper section are related to the type of food each species eats. Some
have comparatively long beaks that are perfect for extracting seeds from fruit; others
have broader and stronger beaks that are designed for cracking hard seeds.
F Differently shaped beaks ate not the only adaptations that have been made during the
developing relationship between parrots and their food plants. Like all of Australia's
many honey-eating birds, the rainbow-coloured lorikeets and the flowers on which they
feed have long co-evolved with features such as the shape and colour of the flowers
adapted to the bird's particular needs, and physical a example, red is the most attractive
colour to birds, and thus flowers which depend on birds for pollination are more often
red, and lorikeets' to gues have bristles which help them to collect as much pollen as
possible.
G Today, most of Australia's parrots inhabit woodland and open forest, arid their
numbers decline towards both deserts and wetter areas. The majority are nomadic to
some degree, moving around to take advantage of feeding and breeding places.
Two of the dry country parrots, the pink and grey galah and the pink, white and yellow
corella have expanded their ranges in recent years. They are among the species that
have adapted well to the changes brought about by European settlement forest telling
created grasslands where galahs and corellas thrive.
H But other parrot species did not fare so well when their environments were altered.
The clearing of large areas of rainforest is probable responsible for the disappearance
of the double-eyed fig parrot, and numbers of ground parrots declined when a great part
of their habitat was destroyed by the draining of coastal swamps. Even some parrot
species that benefited from forest clearing at first are now comforted by a shortage of
nesting sites due to further man-made changes.
I New conditions also sometimes favour an incoming species over one that originally
inhabited the area. For example, after farmers cleared large areas of forest on
Kangaroo Island off the coast of South Australia, the island was colonised by galahs.
They were soon going down holes and destroying black cockatoo eggs in order to take
the hole for their own use. Their success precipitated a partial collapse in the black
cockatoo population when the later lost the struggle for scarce nesting hollows.

B The New Zealand Antarctic Heritage Trust (NZAHT) and its team of conservation
workers recently announced the completion of 10 years of intensive work to save three
historic buildings on Ross Island. As well as the hut at Cape Evans, it has worked on the
Discovery Hut from Scott's 1901-04 expedition at Hut Point, and the hut at Cape Royds,
built for Ernest Shackleton's 1907-09 expedition. When work began, many of the artefacts
were temporarily removed while carpenters from the team of conservation workers
repaired the walls, floors and roof. In Scott's 'zone of command' was the table where team
member Edward Wilson made his enduring biological and botanical illustrations. In a dark
corner nearby, Edward Atkinson had once incubated his moulds and parasites. Of
particular interest is the small workbench and array of test tubes, sample jars and Bunsen
burner stands of biologist Edward Nelson, lit by sunshine through a dusty window. This
was where the young scientist preserved marine specimens as part of his search for new
species and an understanding of the Antarctic food chain.
C The NZAHT executive director Nigel Watson describes the three restored huts as
'fantastic remnants of humans first contact with the continent'. The idea for the birth of the
conservation project, he says, was the fact that we were in great danger of losing them'.
When the on-site work began in 2004, snow and ice were building up around, under and
sometimes inside the huts, damaging the structures and threatening their contents. 'We
now have three buildings that are structurally sound and watertight with a very different
feel - they are drier and lighter and the humidity is reduced. It's a much better environment
for the collection.
D As well as heritage carpenters, the NZAHT team on Ross Island has included experts in
textile, paper and metal conservation: in total, 62 experts from 11 countries have visited
Antarctica to work on the project, often spending a whole summer on-site, sleeping in
tents and popping 25km back to Scott Base for the occasional shower. It became known
as the most exciting conservation project in the world,' says Watson,
'so it attracted top heritage conservation talent.'
E Some of the most exciting discoveries were three intact crates of Mackinlay's Rare Old
Highland Mait Whisky' found encased in ice beneath Shackleton's hut, a paper notebook
that belonged to surgeon, zoologist and photographer George Murray Levick found buried
in dirt at Cape Evans and a small box of 22 cellulose nitrate negatives waiting to be
developed into photographs found in Herbert Ponting's darkroom. But most of the 18,202
items catalogued and conserved are more mundane: food, tools, clothing and other
personal items that were not precious enough to be taken home on the return voyages.
G As a result of the project, the NZAHT has become the world leader in cold- climate
heritage conservation and its members have been interviewed for numerous television
documentaries and radio reports. The Ross Island huts are the jewels in the crown', says
Watson, but there are other historic buildings needing attention. With logistics support
from Antarctica New Zealand, programme managers Al Fastier and Lizzie Meek will be
part of a small team heading to Cape Adare, an exposed site more than 700km north of
Scott Base. The two Cape Adare huts, remnants of an 1898 - 1900 British expedition, 'are
not only the first buildings on the continent', says Watson, but also the only example of
humanity's first buildings on any continent on Earth'
H The three-year restoration effort will involve construction repairs and the removal,
conservation and return of about 1100 objects. Compared with the hut sites on Ross
Island, which are relatively sheltered, Cape Adare is a very remote and challenging place
to work in', says Watson. It's set among the world's biggest colony of Adélie penguins on
an exposed spit of land, and it is important that they don't interrupt the functioning of the
colony in any way while they are there. Lizzie Meek looks forward to the challenge. But I'm
also looking forward to going back to the Ross Island huts and seeing them with fresh
eyes. After so many years of working on them, to be able to step inside and look around to
see what we have accomplished will be amazing.'
I If you can find your way to Antarctica, you'll need a permit to visit any of these huts,
which are each in an Antarctic Specially Protected Area. But there's an easier way to see
them without making the long journey: the trust has partnered with Google to offer Street
View walkthroughs of each of the dwellings, available via Google Earth or through the
NZAHT's website.

READING PASSAGE 3
You should spend about 20 minutes on Questions 27-40, which are based on Reading
Passage 3 on pages 10 and 11.
                           WHALE CULTURE
   A. Most social scientists stubbornly resist the idea that animals have culture. Even
      such advanced cetacean mammals as whales and dolphins clearly don’t have art,
      literature, or architecture. But patient observation over many years has begun to
      reveal behaviours that can only have been learnt from other whales. And that, say
      whale biologists, constitutes culture.
   B. So far, humpback and killer whales provide the best evidence of culture in
      cetaceans, and the song of the male humpback is among the most striking
      examples. Humpback populations in different oceans sing different songs, but
      within the some mean they all stick to the same one. However, during the
      breeding season the sounds change, as it appears that females are drawn to
      novel songs. One male might add an extra set of groans; another might drop a
      series of grunts. Soon all the other males have altered their own rendition to
      incorporate the changes until they are once again singing the same song. Since
      this occurs among thousands of whales spread across a vast part of the planet,
      the change cannot be in response to any factor in the animals’ environment.
      The latest version of the song can be learnt only from other whales - almost
      certainly by imitation.
   c. Culture plays an even bigger part in the life of killer whales. Nowhere is this more
      obvious than along the north-west coast of America, where killer whales are split
      into two distinct populations - ‘residents’ and ‘transients’. They live in the same
      stretch of water, but they don’t mingle. In effect, they belong to two quite separate
      cultures. Residents live in stable groups, or ‘pods’, made up of two or three
      mothers and their offspring - perhaps 20 whales in all. Calves stay with their
      mothers throughout adulthood, and in many years of observation no one has ever
      seen a whale switch pods. Transients travel in smaller, more changeable groups
      of between three and six.
   D. One of the most obvious distinctions between the transient and resident societies
      is the way they impart information. Killer whales detect prey with a range of echo-
      locating clicks, but converse with a vocabulary of squeaks, whistles and whines.
      Transients have only a few such calls, and all transient societies share the same
      ones. Residents have a much more extensive repertoire, and each family group
      has its own unique and distinctive set of calls. Despite regular interaction between
      them, each resident pod sticks firmly to its own dialect. Research shows these
      dialects are maintained for at least 40 years.
E. To qualify as part of killer whale culture, dialects must be learnt from other
    members of the pod. Animals with different dialects share the same waters, so the
    variation can’t be a product of the physical environment. ‘And we can throw out the
    notion that the dialects are inherited,’ says Lance Barrett-Lennard of the University
    of British Columbia. He has spent the past seven years analysing DNA from 270
    whales. His paternity tests reveal that female killer whales invariably attract mates
    from outside their own pod - males with a very different dialect. If dialects were
    programmed by genetics, call patterns from both father and mother would be
    passed on to the calf. ‘A calf uses the calls of its maternal pod very precisely.
    There’s no input from the father,’ says Barrett-Lennard.
F. The question still remains - is this culture? It is, according to Frans de Waal of
   Emory University in Atlanta, who argues that culture is just another biological
   adaptation that has evolved in many creatures. One benefit of viewing culture in
   this way is that you can start to understand how and why it might have arisen in
   these creatures. Whales have several biological attributes that give them an
   advantage in social learning. Apart from their advanced mental abilities, they are
   adept at recognising sounds: ideal for communicating in the marine environment.
   Many species spend years rearing their offspring, and live in small, stable, multi-
   generational societies, a social system that provides ample opportunity for
   teaching and learning.
G. But why have cetaceans evolved the ability to learn from other group members?
   Experts in whale biology believe that ecological factors and the need to adapt to
   sudden changes in the environment played a large part in the emergence of
   culture. Although the ocean is a relatively stable habitat in many ways, it is highly
   changeable in one crucial respect - the availability of food. One moment there
   might be a plentiful supply offish, the next they’ve disappeared. When that
   happens, the past experience of the senior members of the group - and the ability
   to share this knowledge - is a huge asset. The dialects of killer whales allow
   members of the group to identify each other, enabling them to share information
   about food hot spots. Among resident killer whales, it also allows females to avoid
   inbreeding by picking out a mate with a strange dialect from outside their pod, says
   Barrett-Lennard.
H. The importance of sharing information seems to have led to biological changes in
   at least some species of whale. Female killer whales, like humans, are very
   unusual in that they live up to a quarter of a century after they have had their last
   offspring. This only makes sense if they have something useful to give their
   descendants. And what whale matriarchs offer is the most important thing of all -
   cultural knowledge, vital for the group’s survival, passed directly from one
   generation to the next.
