It was a cultural trend that spread across Europe, which emphasised the sovereignty

of the people, as a carrier of values.

B

It was a cultural trend that highlighted all the social and economic inequalities, and

paved the way for the French Revolution.

C It was a cultural trend that spread across Europe, mainly in France, in the early 1700s.

D

It was a cultural trend, according to which the only real art was rational,

understandable by all, and identified itself with Greek and Roman art.

E

It was a cultural trend that was based on the exaltation of reason that, eliminating any

irrational element of knowledge, by itself, revealed the truth without the help of the

transcendental realm. In France this lead to materialism and atheism. 5

12 A teacher in a school for children from 11 to 16 years old sets a code number to unlock his

classroom door. He has a method for remembering his code. He uses:

• the 2 digits of his birth month reversed (for example, February would be 02 reversed to 20);

• then the age of the children in his class at the start of the year with the digits reversed;

• and finally, the date of his birthday in the month, also reversed.

B 903121

C 701131

D 215150

E 115191

13 It has long been thought that birds are much less intelligent than humans and apes. But now it

seems that some species of birds have the same kind of thinking skills as apes. Crows can

create and use tools and are socially sophisticated when finding and protecting food. So how

can a bird with a walnut-size brain be capable of such achievements? The answer is that both

crows and apes have much bigger brains than you would expect from the size of their bodies.

The same pattern is found in humans, parrots and chimps – all intelligent animals.

Which one of the following can be drawn as a conclusion from the above passage?

A Relative brain size is a better indicator of intelligence than absolute brain size.

B Crows are more intelligent than other species of birds.

C Animals that cannot create tools are not intelligent.

D Apes are not as similar to humans as had been thought.

E It could be argued that birds are as intelligent as apes. 7

14 There is a higher than average risk of death or injury to young drivers and their passengers. In

2007, 32 per cent of car driver deaths and 40 per cent of car passenger deaths were people

aged between 17 and 24. Young male drivers were much more likely to be killed or seriously

injured than young female drivers. So in order to reduce the number of road accidents and the

numbers of people killed or injured, young people should not be allowed to drive until they reach

the age of 24.

Which one of the following is an assumption on which this argument depends?

A Most of the accidents involving young people were the fault of the young drivers.

B Young people would not accept the raising of the legal driving age.

C The driving test does not effectively test the skill of drivers.

D The majority of drivers aged between 17 and 24 drive dangerously.

E

Amongst drivers aged between 17 and 24 there are more male drivers than female

drivers.

15 Some disabled people find it difficult to gain access to some of our older public buildings

because the entrances have steps. The problem is most often solved by installing ramps. All

public buildings must be accessible to everyone therefore they must all install ramps.

Which one of the following identifies the flaw in this argument?

A Some older public buildings without ramps may be accessible to disabled people.

B Installing ramps in all public buildings would be extremely expensive.

C

It is unreasonable to suggest that disabled people should be able to access all public

buildings.

D

Disabled people must have access to all buildings not just public ones so all buildings

should have ramps.

E Inaccessible public buildings should be replaced by buildings accessible to all.

16 A street of houses is numbered starting on one side with 1,2,3,4…. At the far end the numbers

continue down the other side in the opposite direction so the largest number is opposite

number 1. The houses are of identical widths so each house has another directly opposite it.

If number 17 is directly opposite number 56, how many houses are there in the street?

A 72

B 37

C 39

D 36

E 73 8

19 If the Carnival Committee does not follow the new European regulations then it may be

impossible to guarantee safety. The probable consequence of this would be a heavy fine, which

would severely reduce the carnival fund, and could be disastrous for the committee’s finances.

Either the committee must meet the safety requirements or the future of the carnival may be

under threat.

Which one of the following best expresses the conclusion of this argument?

A If the European regulations are not followed the carnival may not survive.

B Safety at the carnival has reached dangerously low levels.

C Failure to improve safety could result in a heavy fine.

D A heavy fine could mean financial disaster for the carnival.

E If the regulations are followed then the carnival will take place again next year.

20 87% of the world population are right-handed. The human world is organised to make success

in life easier for the majority. Left-handed people should therefore be considered as having a

disability and receive appropriate support.

Which one of the following, if true, weakens this argument?

A

Amongst top scientists, sportsmen, actors, musicians and politicians the percentage

of left-handed people is much higher than 13%.

B

Left-handed people have poorer spatial skills which makes them more likely to have

car crashes and other serious accidents.

C

Left-handed people are more likely to have health problems such as allergies,

depression, epilepsy and sleeping disorders.

D Hand tools, musical instruments and scissors are designed for use by the majority.

E

Many left-handed people were forced to write with their right hand when they were at

school. 10

21 In North America in the 1800s, arguments were often settled by gunfights, in which two people

stood face to face a distance apart and tried to shoot one another. Recent experiments on

human response times have shown that people act more quickly when responding to an action

than when they are the first to move. This supports the view that our brain uses different routes

in our nervous system to send messages for intentional and reactive movements.

Which one of the following can be drawn as a conclusion from the above passage?

A Gunfighters are best advised to wait for their opponents to move to fire.

B Scientific experiments produce interesting findings.

C Gunfighters who wait for their opponent to move first would always win.

D Brains cannot control our reactive movements.

E Humans can be trained to react more quickly.

22 A taxi driver charges €1.00 per kilometre for the first 3 kilometres of a journey, and 70c per

How far is my house from the station?

A 12 kilometres

B 10 kilometres

C 9 kilometres

D 13 kilometres

E 14 kilometres 11

25 If more workers worked for only four days each week there would be fewer commuters, and

therefore less traffic congestion and less pollution. Also, fewer people would be unemployed

because there would be more work to go around. There is evidence that part-time workers are

absent from work less often than full-time workers, so a person working a four-day week would

be more productive. Less work means less pressure, which means less stress and people

would be happier.

Which one of the following can be drawn as a conclusion from the above passage?

A There would be many benefits to working a four-day week.

B

There would be less pressure on the health services if most workers were on a fourday week.

C The economy would be more competitive if people worked more productively.

D The government should enforce a four-day working week.

E People choosing to work a four-day week would have to take a 20% pay cut. 13

26 Migratory birds which are unable to fly long distances without resting have to use the shortest

distance over water in their flights to and from Africa, and so they cross at the Straits of

Gibraltar. It is essential for these birds, some of which are very rare, that the route remains

open. For that reason, it is important that plans to build electricity-generating wind farms on the

hills surrounding the Straits of Gibraltar do not go ahead.

Which one of the following is an assumption on which this argument depends?

A The planned wind farms will make it dangerous for migratory birds to use their route.

B Electricity-generating wind farms have to be built on hills.

C The birds that migrate across the Straits of Gibraltar are close to extinction.

D Other species of bird can fly further and can thus use other routes in their migration.

E There are no plans to build wind farms at other places along the coast.

27 When mobile phones were introduced there were concerns about the microwaves produced

and the effects that these could have on the brain, given that phones would be held close to the

ear when being used. These concerns have been shown to be mistaken since mobile phones

are used for sending text messages far more than for making phone calls. Sending a text

message does not require the phone to be anywhere near to the brain so it cannot cause any

problems.

Which one of the following identifies the flaw in this argument?

A It ignores the possible effects of the phone calls that are made.

B

It ignores evidence suggesting that text messaging is only popular in certain age

groups.

C

It does not consider uses of mobile phones other than making phone calls and

sending text messages.

D

It does not consider other technology such as wireless internet which could cause

similar problems.

E

It ignores research showing that microwaves from the phones cannot penetrate far

enough to reach the brain. 14

30 Apples cost 30c each, bananas cost 40c each and oranges cost 50c each. Daniel spends

exactly €2 buying fruit.

Which of the statements below are correct?

1 He cannot have exactly 3 apples.

2 He must have at least one banana.

3 He has 4, 5 or 6 fruits.

4 If he has all 3 types of fruit, he must have fewer apples than bananas and oranges

combined.

A 1, 3 and 4 only

B 1, 2 and 4 only

C 1, 2 and 3 only

D 2, 3 and 4 only

E 1, 2, 3 and 4

31 A comparison has been made between fast food restaurants and factories. This is not as

unrealistic as it might first appear. Fast food is mass-produced, as heavily processed as any

other factory product, and restaurant workers have jobs which are just as routine and boring as

those in manufacturing. So not only does fast food taste the same everywhere, but all workers

involved are on low wages and have little power to improve their conditions.

Which one of the following best expresses the conclusion of this argument?

A It is not unrealistic to compare fast food restaurants with factories.

B Mass production in factories leads to poor working conditions.

C Workers who do routine and boring jobs are often poorly paid.

D All fast food tastes the same because it is heavily processed.

E Working in a fast food restaurant is no different from working in a factory. 16

32 Recent research suggests that people are becoming less inclined to follow medical advice

about how to prevent ill-health. They say that there is too much advice and it is often

contradictory. However the general population is living longer and is healthier. This suggests

that people are more aware of what is good for their own health and wellbeing than the medical

profession is.

Which one of the following, if true, weakens this argument?

A

The health improvements are in areas that exactly match the medical advice given by

doctors.

B People now have easy access to websites giving information on health.

C

People believe that they know better than doctors how to improve their own health

and wellbeing.

D

Advances in medicine have meant that doctors give advice on a wider range of

issues.

E Doctors prefer to give advice rather than medication.

33 Over the last twenty years the number of people, including children, classed as overweight, and

therefore at risk of serious health problems, has risen alarmingly. This trend could be caused by

an increase in the amount people eat or by a decrease in the amount of exercise they take.

Most of us exercise less than people did twenty years ago, and the average number of calories

consumed per person is now less than it was twenty years ago. So the increase in the number

of overweight people is clearly caused by lack of exercise. Thus the government does not need

to worry about trying to change people’s diets.

Which one of the following identifies the flaw in this argument?

A Some individuals may have increased their calorie intake.

B Some people may exercise more than the average.

C The government may need to worry about costs to the health service.

D Children may use up more calories through exercise than adults.

E Some individuals may have health problems which cause an increase in weight. 17

36 A fishing club wishes to send out a mailing to its 1000 members. All members receive a

magazine (100_g). There are 50 committee members who receive minutes (50_g). A

questionnaire (75_g) will be sent to 100 members. No committee members will be sent a

questionnaire. The envelope used for all mailings weighs 10_g.

C € 67 .00

D € 230 .00

E € 350 .00

37 The general public cannot understand laws and legal documents unless they are written in clear

and simple language. Therefore, the traditional style in which laws and legal documents are

written must change. Citizens in a democracy must be able to understand what their legal rights

and duties are.

Which one of the following best expresses the conclusion of this argument?

A There must be a change in the style in which laws and legal documents are written.

B It is necessary in a democracy for citizens to know their legal rights and duties.

C

Many laws and legal documents are written in old-fashioned and complicated

language.

D

The general public can fully understand only those laws and documents written in

simple language.

E

If citizens can understand laws and legal documents, they will be able to play their

proper role in a democracy. 19

38 Many countries spent billions on vaccines in response to advice that a virus had the potential to

kill millions. These countries are now trying to sell the stockpiles of vaccines which they do not

need. There is concern that advice given by officials may have been influenced by

pharmaceutical companies. Clearly, such companies would have an interest in making sure that

governments spent large quantities of money on vaccines that they produced. It is essential that

an investigation into this matter takes place as soon as possible so that those responsible can

be held to account.

Which one of the following is an assumption on which this argument depends?

A The advice given by officials was not appropriate.

B The pharmaceutical companies influenced the advice given by officials.

C It will not be possible for the stockpiles of vaccines to be sold.

D The pharmaceutical companies misjudged the dangers of the virus.

E

Groups with financial interests do not advise officials in other areas of decision

making.
