2 Y Paragraph 2 states, During the breeding season, the

amount of venom in the male platypus increases.

3 NG There is nothing in the passage about this!


5 Y The last paragraph states, Platypus are wild animals

with specialised living requirements. It is illegal formembers of the public to keep them in captivity. A

platypus which has been accidentally captured along astream or found wandering in an unusual place shouldnever be taken home and treated as a pet, even for a

brief time. The animal will not survive the experience.

6 (movable) spur The second paragraph states that, the platypus hasamoveable spur on its hind foot

7 two buds The third paragraph states that, the femaleplatypusdevelops two buds which drop off in their

14 v Paragraph B states, The first experiments in recorded

scientific history on the effects of people not getting

enough sleep took place in the late 1800s, threevolunteers were deprived of sleep for a total of 90

hours, in 1920 more experiments in sleep

deprivation were conducted - the topic of research into

sleep deprivation is established. Several examples of the effects of sleep deprivation

upon the body, 'people who are sleep deprived for

periods of more than 60 hours try to fall asleep in anyenvironment and show signs of mental disturbances,

visions and hallucinations. As the length of sleep

deprivation increases, so too does the mental decline in

an individual. All these examples have been recordedafter monitoring the effects of sleep deprivation.

15 x Paragraph C is primarily reporting on sleepexperiments in isolated areas. The first sentence talks

about, Studies of sleep patterns inremote areas of

the world. The passage describes the process of

the experiments, All participants were required to getrid of all clocks, watches and talks about the

outcome of the experiments, most people slept

around 10 hours per day and all participants reported

feeling completely invigorated and refreshed. Note: although there is reference to the Antarctic, it is

not even the location of the experiments

16 ix Paragraph D discusses sleep interruptions such as

traffic and aircraft noise in urban areas. It points to

the results of a study in which the participants were

exposed to the loud noise of a major urban roadnamely, participants had depression and mood scores

similar to people with clinical depressiona reduction

in certain performance tasks was also noted.



17 vii Paragraph E discusses in sentences 1 & 2 people who

reportedly, who claim and who may be short

sleepers. These words indicate that its a challenge todefine who are short sleepers (ie those who have

reduced sleeping hours)

18 i Paragraph F deals with a study in Norway which

monitored the states of being awake in bus drivers. It

reveals that the drivers were having a series of micro-

sleeps short periods of timewhere they areclassified as being asleep.

19 B In Paragraph A Limpton states: the average amount

of sleep most people get per night - is not enough.

20 C In Paragraph B Oswald states: chronic sleep

deprivation often leads to drastic consequences.

21 A In Paragraph E Joske states that genetically short

sleepers may have some natural resistance to the

effects of sleep deprivation but it is not entirely certainwhy some people seem to require more and others

less. (ie although he does not know why exactly, he

believes that some need more and others less sleep).

22 D In Paragraph D Tom Grimstead used an actimeter

a device which measures the amount of movement in

sleep - was used to gauge the quality of theparticipants sleep.

23 A In Paragraph E Joske says, When we brought longand short sleepers into controlled environments...we

found that all participants slept between nine and ten

hours



24 D

In any

order

In paragraph D Grimstead reported that participants

emerged in a depressed-like state after four days ofsleep interruptions.

25 E In paragraph B, Kleitman reported, signs of mental

disturbances, visions and hallucinations.

26 B The majority of the passage cites examples of studies

the first experiments, sleep patterns, sleepinterruptions.

A and C are wrong because not all of the studies deal

with the importance of sleep nor how much sleep we

need. D is wrong because only one paragraph deals with

sleep patterns - a small part of the passage.

E is not correct because while there are some up-to-

date perspectives, some are dating back to the 1920s.

27 D A is wrong because the final paragraph states fog cannot form in

dry conditions. B is wrong because the last pargraph clearly

states the opposite: Dewappears far more frequently (than

fog). C is wrong as the 3rd paragraph states that it is

desalination that is being tried in Senegal.



28 C A is wrong because the 3rd paragraph states that small-scale

desalination is surprisingly energy-efficient. B is wrong thereis no mention of this in the text. D is wrong, large-scale

desalination burns a lot of fossil fuel.

29 C A and D are wrong because the 2nd paragraph points out thatArtesian wells, rivers and lakes only account for about 0.1 and

0.5 million km3 respectively. B is wrong rain and snow are

included in rivers and lakes.

30 B The 3rd paragraph states: In parts of Senegal, for example, the

greenhouse effect has been one way to desalinate seawater

whereby the salt in the water is separated from the water through

a process of evaporation.

31 C In relation to energy efficiency in the process of desalination, the

3rd paragraph states: In larger scale production however, the

energy efficiency plummets.

32 E Paragraph 4 states: The atmosphere, for example, contains vast

amounts of fresh water composed of 2% condensed water in the

form of clouds and 98% water vapour.

33 A The final paragraph states: Dew however appears far more

frequently and is less subject to the constraints of climate

(temperature) and geography (location).

34 F The final paragraph states: When the temperature is lowered

over a short space of time by ten degrees or so, the water-

harvesting possibilities from the air yield an amazing ten grams of

water from each cubic meter of air - significant drops in airtemperature make for greater yields.




36 T The 2nd paragraph lists all the various sources of fresh water

among them: Glaciers and snowGround waterArtesian

wells, rivers and lakes and rain and snow.

37 F Regarding the amount of fresh water extracted from the sea, the

3rd paragraph states: some estimates put the annual quantity

of desalinated water at only around ten cubic kilometers a tiny

amount given the amount of sea water available.


39 T The final paragraph states: In order for dew to form there needs

to be humidity in the air and a reasonably clear sky.
