Why do people collect things?
People from almost every culture love collecng things. They might collect stamps, books, cards, priceless painngs
or worthless cket stubs to old sports games. Their collecon might hang on the walls of a mansion or be stored in a
box under the bed. So what is it that drives people to collect? Psychologist Dr Maria Richter argues that the urge to
collect is a basic human characterisc. According to her, in the very rst years of life we form emoonal connecons
with lifeless objects such as so toys. And these posive relaonships are the starng point for our fascinaon with
collecng objects. In fact, the desire to collect may go back further sll. Sciensts suggest that for some ancient
humans living hundreds of thousands of years ago, collecng may have had a serious purpose. Only by collecng
sucient food supplies to last through freezing winters or dry summers could our ancestors stay alive unl the
weather improved.
It turns out that even collecng for pleasure has a very long history. In 1925, the archaeologist Leonard Woolley was
working at a site in the historic Babylonian city of Ur. Woolley had travelled to the region intending only to excavate
the site of a palace. Instead, to his astonishment, he dug up artefacts which appeared to belong to a 2,500year-old
museum. Among the objects was part of a statue and a piece of a local building. And accompanying some of the
artefacts were descripons like modern-day labels. These texts appeared in three languages and were carved into
pieces of clay. It seems likely that this early private collecon of objects was created by Princess Ennigaldi, the
daughter of King Nabonidus. However, very lile else is known about Princess Ennigaldi or what her movaons were
for seng up her collecon.

Some signicant private collecons of this sort date from the eenth century. One of the rst belonged to the
Medici family. The Medicis became a powerful polical family in Italy and later a royal house, but banking was
originally the source of all their wealth. The family started by collecng coins and valuable gems, then artworks and
anques from around Europe. In 1570 a secret 'studio' was built inside the Palazzo Medici to house their growing
collecon. This exhibion room had solid walls without windows to keep the valuable collecon safe.
In the seventeenth century, another fabulous collecon was created by a Danish physician named Ole Worm. His
collecon room contained numerous skeletons and specimens, as well as ancient texts and a laboratory. One of Ole
Worm's movaons was to point out when other researchers had made mistakes, such as the false claim that birds
of paradise had no feet. He also owned a great auk, a species of bird that has now become exnct, and the illustraon
he produced of it has been of value to later sciensts.
The passion for collecng was just as strong in the nineteenth century. Lady Charloe Guest spoke at least six
languages and became well-known for translang English books into Welsh. She also travelled widely throughout
Europe acquiring old and rare poery, which she added to her collecon at home in southern England. When Lady
Charloe died in 1895 this collecon was given to the Victoria and Albert Museum in London. At around the same

lOMoARcPSD| 58968691
me in the north of England, a wealthy goldsmith named Joseph Mayer was building up an enormous collecon of
artefacts, parcularly those dug up from sites in his local area. His legacy, the Mayer Trust, connues to fund public
lectures in accordance with his wishes.
In the tweneth century, the writer Beatrix Poer had a magnicent collecon of books, insects, plants and other
botanical specimens. Most of these were donated to London's Natural History Museum, but Beatrix held on to her
cabinets of fossils, which she was parcularly proud of. In the United States, President Franklin D. Roosevelt began
his stamp collecon as a child and connued to add to it all his life. The stress associated with being president was
easier to cope with, Roosevelt said, by taking me out to focus on his collecon. By the end of his life this had
expanded to include model ships, coins and artworks.
Most of us will never own collecons so large or valuable as these. However, the examples given here suggest that
collecng is a passion that has been shared by countless people over many centuries.

READING PASSAGE 1
You should spend about 20 minutes on Quesons 1-13 which are based on Reading Passage 1 below.
Why we need to protect polar bears
Polar bears are being increasingly threatened by the eects of climate change, but their disappearance could have
far-reaching consequences. They are uniquely adapted to the extreme condions of the Arcc Circle, where
temperatures can reach -40°C. One reason for this is that they have up to 11 cenmetres of fat underneath their skin.
Humans with comparave levels of adipose ssue would be considered obese and would be likely to suer from
diabetes and heart disease. Yet the polar bear experiences no such consequences. A 2014 study by Shi Ping Liu and
colleagues sheds light on this mystery. They compared the genec structure of polar bears with that of their closest
lOMoARcPSD| 58968691
relaves from a warmer climate, the brown bears. This allowed them to determine the genes that have allowed polar
bears to survive in one of the toughest environments on Earth. Liu and his colleagues found the polar bears had a
gene known as APoB, which reduces levels of low-density lipoproteins (LDLs) – a form of ‘badcholesterol. In humans,
mutaons of this gene are associated with increased risk of heart disease. Polar bears may therefore be an important
study model to understand heart disease in humans.
The genome of the polar bear may also provide the soluon for another condion, one that parcularly aects our
older generaon: osteoporosis. This is a disease where bones show reduced density, usually caused by insucient
exercise, reduced calcium intake or food starvaon. Bone ssue is constantly being remodelled, meaning that bone
is added or removed, depending on nutrient availability and the stress that the bone is under. Female polar bears,
however, undergo extreme condions during every pregnancy. Once autumn comes around, these females will dig
maternity dens in the snow and will remain there throughout the winter, both before and aer the birth of their cubs.
This process results in about six months of fasng, where the female bears have to keep themselves and their cubs
alive, depleng their own calcium and calorie reserves. Despite this, their bones remain strong and dense.
Physiologists Alanda Lennox and Allen Goodship found an explanaon for this paradox in 2008. They discovered that
pregnant bears were able to increase the density of their bones before they started to build their dens. In addion,
six months later, when they nally emerged from the den with their cubs, there was no evidence of signicant loss
of bone density. Hibernang brown bears do not have this capacity and must therefore resort to major bone
reformaon in the following spring. If the mechanism of bone remodelling in polar bears can be understood, many
bedridden humans, and even astronauts, could potenally benet.
The medical benets of the polar bear for humanity certainly have their importance in our conservaon eorts, but
these should not be the only factors taken into consideraon. We tend to want to protect animals we think are
intelligent and possess emoons, such as elephants and primates. Bears, on the other hand, seem to be perceived
as stupid and in many cases violent. And yet anecdotal evidence from the eld challenges those assumpons,
suggesng for example that polar bears have good problem-solving abilies. A male bear called GoGo in Tennoji Zoo,
Osaka, has even been observed making use of a tool to manipulate his environment. The bear used a tree branch on
mulple occasions to dislodge a piece of meat hung out of his reach. Problem-solving ability has also been witnessed
in wild polar bears, although not as obviously as with GoGo. A calculated move by a male bear involved running and
jumping onto barrels in an aempt to get to a photographer standing on a plaorm four metres high.
In other studies, such as one by Alison Ames in 2008, polar bears showed deliberate and focused manipulaon. For
example, Ames observed bears pung objects in piles and then knocking them over in what appeared to be a game.
The study demonstrates that bears are capable of agile and thought-out behaviours. These examples suggest bears
have greater creavity and problem-solving abilies than previously thought.
As for emoons, while the evidence is once again anecdotal, many bears have been seen to hit out at ice and snow
seemingly out of frustraon when they have just missed out on a kill. Moreover, polar bears can form unusual
relaonships with other species, including playing with the dogs used to pull sleds in the Arcc. Remarkably, one
hand-raised polar bear called Agee has formed a close relaonship with her owner Mark Dumas to the point where
they even swim together. This is even more astonishing since polar bears are known to acvely hunt humans in the
wild.
If climate change were to lead to their exncon, this would mean not only the loss of potenal breakthroughs in
human medicine, but more importantly, the disappearance of an intelligent, majesc animal.

READING PASSAGE 3
You should spend about 20 minutes on Quesons 27-40 which are based on Reading Passage 3 below.
Chelsea Rochman, an ecologist at the University of California, Davis, has been trying to answer a dismal queson: Is
everything terrible, or are things just very, very bad?
Rochman is a member of the Naonal Center for Ecological Analysis and Synthesis’s marinedebris working group, a
collecon of sciensts who study, among other things, the growing problem of marine debris, also known as ocean
trash. Plenty of studies have sounded alarm bells about the state of marine debris; in a recent paper published in the
journal Ecology, Rochman and her colleagues set out to determine how many of those perceived risks are real.
Oen, Rochman says, sciensts will end a paper by speculang about the broader impacts of what they’ve found.
For example, a study could show that certain seabirds eat plasc bags, and go on to warn that whole bird populaons
are at risk of dying out. ‘But the truth was that nobody had yet tested those perceived threats,’ Rochman says.
There wasn’t a lot of informaon.
Rochman and her colleagues examined more than a hundred papers on the impacts of marine debris that were
published through 2013. Within each paper, they asked what threats sciensts had studied – 366 perceived threats
in all – and what theyd actually found.
lOMoARcPSD| 58968691
In 83 percent of cases, the perceived dangers of ocean trash were proven true. In the remaining cases, the working
group found the studies had weaknesses in design and content which aected the validity of their conclusions – they
lacked a control group, for example, or used faulty stascs.
Strikingly, Rochman says, only one well-designed study failed to nd the eect it was looking for, an invesgaon of
mussels ingesng microscopic bits. The plasc moved from the mussels’ stomachs to their bloodstreams, sciensts
found, and stayed there for weeks – but didn’t seem to stress out the shellsh.
While mussels may be ne eang trash, though, the analysis also gave a clearer picture of the many ways that
ocean debris is bothersome.
Within the studies they looked at, most of the proven threats came from plasc debris, rather than other materials
like metal or wood. Most of the dangers also involved large pieces of debris – animals geng entangled in trash, for
example, or eang it and severely injuring themselves.
But a lot of ocean debris is ‘microplasc’, or pieces smaller than ve millimeters. These may be ingredients used in
cosmecs and toiletries, bers shed by synthec clothing in the wash, or eroded remnants of larger debris. Compared
to the number of studies invesgang largescale debris, Rochman’s group found lile research on the eects of these
ny bits. ‘There are a lot of open quesons sll for microplasc,’ Rochman says, though she notes that more papers
on the subject have been published since 2013, the cuto point for the group’s analysis.
There are also, she adds, a lot of open quesons about the ways that ocean debris can lead to sea-creature death.
Many studies have looked at how plasc aects an individual animal, or that animal’s ssues or cells, rather than
whole populaons. And in the lab, sciensts oen use higher concentraons of plasc than whats really in the ocean.
None of that tells us how many birds or sh or sea turtles could die from plasc polluon or how deaths in one
species could aect that animal’s predators, or the rest of the ecosystem.
‘We need to be asking more ecologically relevant quesons,Rochman says. Usually, sciensts don’t know exactly
how disasters such as a tanker accidentally spilling its whole cargo of oil and pollung huge areas of the ocean will
aect the environment unl aer they’ve happened. ‘We don’t ask the right quesons early enough,she says. But
if ecologists can understand how the slow-moving eect of ocean trash is damaging ecosystems, they might be able
to prevent things from geng worse.
Asking the right quesons can help policy makers, and the public, gure out where to focus their aenon. The
problems that look or sound most dramac may not be the best places to start. For example, the name of the ‘Great
Pacic Garbage Patch’ a collecon of marine debris in the northern Pacic Ocean – might conjure up a vast, oang
trash island. In reality though, much of the debris is ny or below the surface; a person could sail through the area
without seeing any trash at all. A Dutch group called The Ocean Cleanupis currently working on plans to put
mechanical devices in the Pacic Garbage Patch and similar areas to suck up plasc. But a recent paper used
simulaons to show that strategically posioning the cleanup devices closer to shore would more eecvely reduce
polluon over the long term.
‘I think clearing up some of these mispercepons is really important,Rochman says. Among sciensts as well as in
the media, she says, A lot of the images about strandings and entanglement and all of that cause the percepon that
plasc debris is killing everything in the ocean.Interrogang the exisng scienc literature can help ecologists gure
out which problems really need addressing, and which ones theyd be beer o – like the mussels absorbing and
ignoring.

Why we need to protect polar bears
Polar bears are being increasingly threatened by the effects of climate change, but their disappearance could have
far-reaching consequences. They are uniquely adapted to the extreme conditions of the Arctic Circle, where
temperatures can reach -40°C. One reason for this is that they have up to 11 centimetres of fat underneath their skin.
Humans with comparative levels of adipose tissue would be considered obese and would be likely to suffer from
diabetes and heart disease. Yet the polar bear experiences no such consequences. A 2014 study by Shi Ping Liu and
colleagues sheds light on this mystery. They compared the genetic structure of polar bears with that of their closest lOMoAR cPSD| 58968691
relatives from a warmer climate, the brown bears. This allowed them to determine the genes that have allowed polar
bears to survive in one of the toughest environments on Earth. Liu and his colleagues found the polar bears had a
gene known as APoB, which reduces levels of low-density lipoproteins (LDLs) – a form of ‘bad’ cholesterol. In humans,
mutations of this gene are associated with increased risk of heart disease. Polar bears may therefore be an important
study model to understand heart disease in humans.
The genome of the polar bear may also provide the solution for another condition, one that particularly affects our
older generation: osteoporosis. This is a disease where bones show reduced density, usually caused by insufficient
exercise, reduced calcium intake or food starvation. Bone tissue is constantly being remodelled, meaning that bone

however, undergo extreme conditions during every pregnancy. Once autumn comes around, these females will dig
maternity dens in the snow and will remain there throughout the winter, both before and after the birth of their cubs.
This process results in about six months of fasting, where the female bears have to keep themselves and their cubs
alive, depleting their own calcium and calorie reserves. Despite this, their bones remain strong and dense.
Physiologists Alanda Lennox and Allen Goodship found an explanation for this paradox in 2008. They discovered that
pregnant bears were able to increase the density of their bones before they started to build their dens. In addition,
six months later, when they finally emerged from the den with their cubs, there was no evidence of significant loss
of bone density. Hibernating brown bears do not have this capacity and must therefore resort to major bone
reformation in the following spring. If the mechanism of bone remodelling in polar bears can be understood, many
bedridden humans, and even astronauts, could potentially benefit.
The medical benefits of the polar bear for humanity certainly have their importance in our conservation efforts, but
these should not be the only factors taken into consideration. We tend to want to protect animals we think are
intelligent and possess emotions, such as elephants and primates. Bears, on the other hand, seem to be perceived
as stupid and in many cases violent. And yet anecdotal evidence from the field challenges those assumptions,
suggesting for example that polar bears have good problem-solving abilities. A male bear called GoGo in Tennoji Zoo,
Osaka, has even been observed making use of a tool to manipulate his environment. The bear used a tree branch on
multiple occasions to dislodge a piece of meat hung out of his reach. Problem-solving ability has also been witnessed
in wild polar bears, although not as obviously as with GoGo. A calculated move by a male bear involved running and
jumping onto barrels in an attempt to get to a photographer standing on a platform four metres high.
In other studies, such as one by Alison Ames in 2008, polar bears showed deliberate and focused manipulation. For
example, Ames observed bears putting objects in piles and then knocking them over in what appeared to be a game.
The study demonstrates that bears are capable of agile and thought-out behaviours. These examples suggest bears
have greater creativity and problem-solving abilities than previously thought.
As for emotions, while the evidence is once again anecdotal, many bears have been seen to hit out at ice and snow
– seemingly out of frustration – when they have just missed out on a kill. Moreover, polar bears can form unusual
relationships with other species, including playing with the dogs used to pull sleds in the Arctic. Remarkably, one
hand-raised polar bear called Agee has formed a close relationship with her owner Mark Dumas to the point where
they even swim together. This is even more astonishing since polar bears are known to actively hunt humans in the wild.
If climate change were to lead to their extinction, this would mean not only the loss of potential breakthroughs in
human medicine, but more importantly, the disappearance of an intelligent, majestic animal. lOMoAR cPSD| 58968691 Questions 1-7

You should spend about 20 minutes on Questions 27-40 which are based on Reading Passage 3 below.
Chelsea Rochman, an ecologist at the University of California, Davis, has been trying to answer a dismal question: Is
everything terrible, or are things just very, very bad?
Rochman is a member of the National Center for Ecological Analysis and Synthesis’s marinedebris working group, a
collection of scientists who study, among other things, the growing problem of marine debris, also known as ocean
trash. Plenty of studies have sounded alarm bells about the state of marine debris; in a recent paper published in the
journal Ecology, Rochman and her colleagues set out to determine how many of those perceived risks are real.
Often, Rochman says, scientists will end a paper by speculating about the broader impacts of what they’ve found.
For example, a study could show that certain seabirds eat plastic bags, and go on to warn that whole bird populations
are at risk of dying out. ‘But the truth was that nobody had yet tested those perceived threats,’ Rochman says.
‘There wasn’t a lot of information.’
Rochman and her colleagues examined more than a hundred papers on the impacts of marine debris that were
published through 2013. Within each paper, they asked what threats scientists had studied – 366 perceived threats
in all – and what they’d actually found. lOMoAR cPSD| 58968691
In 83 percent of cases, the perceived dangers of ocean trash were proven true. In the remaining cases, the working
group found the studies had weaknesses in design and content which affected the validity of their conclusions – they
lacked a control group, for example, or used faulty statistics.
Strikingly, Rochman says, only one well-designed study failed to find the effect it was looking for, an investigation of
mussels ingesting microscopic bits. The plastic moved from the mussels’ stomachs to their bloodstreams, scientists
found, and stayed there for weeks – but didn’t seem to stress out the shellfish.
While mussels may be fine eating trash, though, the analysis also gave a clearer picture of the many ways that
ocean debris is bothersome.
Within the studies they looked at, most of the proven threats came from plastic debris, rather than other materials
like metal or wood. Most of the dangers also involved large pieces of debris – animals getting entangled in trash, for
example, or eating it and severely injuring themselves.
But a lot of ocean debris is ‘microplastic’, or pieces smaller than five millimeters. These may be ingredients used in
cosmetics and toiletries, fibers shed by synthetic clothing in the wash, or eroded remnants of larger debris. Compared
to the number of studies investigating largescale debris, Rochman’s group found little research on the effects of these
tiny bits. ‘There are a lot of open questions still for microplastic,’ Rochman says, though she notes that more papers
on the subject have been published since 2013, the cutoff point for the group’s analysis.
There are also, she adds, a lot of open questions about the ways that ocean debris can lead to sea-creature death.
Many studies have looked at how plastic affects an individual animal, or that animal’s tissues or cells, rather than
whole populations. And in the lab, scientists often use higher concentrations of plastic than what’s really in the ocean.
None of that tells us how many birds or fish or sea turtles could die from plastic pollution – or how deaths in one
species could affect that animal’s predators, or the rest of the ecosystem.
‘We need to be asking more ecologically relevant questions,’ Rochman says. Usually, scientists don’t know exactly
how disasters such as a tanker accidentally spilling its whole cargo of oil and polluting huge areas of the ocean will
affect the environment until after they’ve happened. ‘We don’t ask the right questions early enough,’ she says. But
if ecologists can understand how the slow-moving effect of ocean trash is damaging ecosystems, they might be able
to prevent things from getting worse.
Asking the right questions can help policy makers, and the public, figure out where to focus their attention. The
problems that look or sound most dramatic may not be the best places to start. For example, the name of the ‘Great
Pacific Garbage Patch’ – a collection of marine debris in the northern Pacific Ocean – might conjure up a vast, floating
trash island. In reality though, much of the debris is tiny or below the surface; a person could sail through the area
without seeing any trash at all. A Dutch group called ‘The Ocean Cleanup’ is currently working on plans to put
mechanical devices in the Pacific Garbage Patch and similar areas to suck up plastic. But a recent paper used
simulations to show that strategically positioning the cleanup devices closer to shore would more effectively reduce pollution over the long term.
‘I think clearing up some of these misperceptions is really important,’ Rochman says. Among scientists as well as in
the media, she says, ‘A lot of the images about strandings and entanglement and all of that cause the perception that
plastic debris is killing everything in the ocean.’ Interrogating the existing scientific literature can help ecologists figure
out which problems really need addressing, and which ones they’d be better off – like the mussels – absorbing and ignoring. Questions 27-33

Rochman and her colleagues were the first people to research the problem of marinedebris. 28
The creatures most in danger from ocean trash are certain seabirds. lOMoAR cPSD| 58968691 29
The studies Rochman has reviewed have already proved that populations of some birdswill soon become extinct. 30
Rochman analysed papers on the different kinds of danger caused by ocean trash. 31
Most of the research analysed by Rochman and her colleagues was badly designed.32 One study examined
by Rochman was expecting to find that mussels were harmed by eating plastic.
33 Some mussels choose to eat plastic in preference to their natural diet. Questions 34-39 Complete the notes below.
