- Question 1 of 60
1. Question
Research reveals that, in a given period of the 20th century, top footballers (defined as those who had played for their country’s team) lived, on average, almost 5 years longer than middle ranking footballers. We can conclude therefore that for the top footballers, success had a beneficial effect on their lifespan.
Which one of the following is the best statement of the flaw in the argument above?
CorrectIncorrect - Question 2 of 60
2. Question
One of the foolish but persisting fantasies of the Olympic movement is that the Games are, or were, or will be, or even ought to be, completely free of politics. It is difficult to understand how this foolish belief continues, but the facts are these: the nations lining up to host the games are motivated not by unattainable ideals but by a legitimate desire to promote the excellence of their citizens; and the nations who have boycotted the games in the past have done so to make genuine political points.
Which one of the following is a conclusion which can be drawn from the above passage?
CorrectIncorrect - Question 3 of 60
3. Question
There is concern at the moment about the way in which football referees are treated by players during games. The Football Association and the Referees’ Association feel that there is too much verbal (and physical) abuse directed at referees. Various solutions have been suggested such as only allowing the captain of each team to approach and talk to the referee. The major difficulty is how such new rules should be introduced. The preferred suggestion seems to be that the rules should be changed first in the amateur game, the aim being to improve discipline in the game from the bottom upwards, until the whole game is improved.
Which one of the following, if true, would most weaken the argument above?
CorrectIncorrect - Question 4 of 60
4. Question
The purpose of an election is to decide what policies are supported by the people. However, in elections the concept of ‘tactical voting’ is becoming increasingly common. The argument is a simple one:
Party X will never be beaten by party Y but party Z could win with a few extra votes. Therefore, you should transfer your vote from party Y to party Z to make sure that party X is beaten.
This reasoning is perfectly sound if your main objective is to vote a party out. Unfortunately, if you support party Y then there is no guarantee that party Z will support the same principles.
Which one of the following is the conclusion that could best be drawn from the above passage?
CorrectIncorrect - Question 5 of 60
5. Question
Despite much opposition to the idea, modern musical trends such as hip-hop have a place in the world of opera. Traditional opera is a powerful musical experience. However, modern musicians should not necessarily stick with the traditional form. Modern musical forms which fuse staged drama, singing and contemporary or ethnic trends in music are also powerful musical experiences. Glyndebourne’s youth operas ‘Misper’ and ‘Zoe’, and its Mozart hip-hopera, ‘School 4 Lovers’, enjoyed critical and box office success and attracted hip-hop audiences. Moving away from the snobbery of tradition gives a much wider audience access to transformative musical experience.
Which one of the following best expresses the main conclusion of the passage?
CorrectIncorrect - Question 6 of 60
6. Question
Over 30 years ago, the smallpox virus was eradicated from the natural environment, but examples of it are still preserved in two laboratories. It is planned, however, to destroy these remaining viruses. Given that this will be the first example of a deliberate destruction of an entire species, we should think again before destroying these viruses. Years ago we thought we had the right to kill as many creatures as we liked, but now we realise we have no such right. Furthermore, we cannot know the future; we cannot justify destroying something that could be of enormous value to us one day, valuable in ways we cannot even think of now. And anyway, what possible harm can captive viruses do to us?
Which one of the following best expresses the main conclusion of the above argument?
CorrectIncorrect - Question 7 of 60
7. Question
When driving, if the car in front of you brakes suddenly, you need to be able to stop without crashing into it. The easiest rule-of-thumb is the two second rule. You choose a reference point that the vehicle in front of you is passing then say aloud: ‘Only a fool breaks the two second rule’. If you reach the reference point before you have finished the saying you need to pull back. This works at all speeds. However, when there are adverse road conditions or the road is narrow you need to double your braking distance. These practices will enable you to avoid such crashes.
Which one of the following is an underlying assumption of the argument above?
CorrectIncorrect - Question 8 of 60
8. Question
If for a number of hours each day you’re having experiences on the computer where there are no consequences, that may have an implication for antisocial behaviour. In real life you can’t undo something; you can’t bring someone back to life once you’ve stabbed them. On a computer you can play the game again. It may be that for people who spend most of their time playing computer games involving killing others, real bleeding to death has no meaning. Studies of brain activity show that there is less prefrontal cortex activity in the brains of screen-obsessed teenagers than in the brains of those who spend little time on computer games. The prefrontal cortex area of the brain is where we process ideas of sequence, consequences and empathy.
Which one of the following can be drawn as a conclusion of the passage above?
CorrectIncorrect - Question 9 of 60
9. Question
We constantly split our attention between the people we are with and what’s happening on our mobile phone screens. On-screen multi-tasking makes us less efficient as well as less emotionally engaged with others. It takes 64 seconds to recover our train of thought after interruption by a message (that’s 8.5 hours a week wasted if we check our screens every five minutes) and when we’ve sent an email or SMS text message, the brain goes through a series of semi-conscious calculations as we wonder when and how the recipient will reply. The result is that we’re not ‘present’ for several minutes afterwards. In order to function effectively in the workplace, we need to switch off our communication hardware.
Which one of the following is the best statement of the flaw in the above argument?
CorrectIncorrect - Question 10 of 60
10. Question
If the media give publicity to certain types of crime, it may encourage criminals to carry out ‘copy cat’ offences. If, however, they were forbidden to divulge details of crimes, this would amount to censorship. The freedom of speech of the media is too important to sacrifice, so the media should be free to report crime even if this means some crimes are committed which would not otherwise be committed.
Which one of the following expresses the main conclusion of the above argument?
CorrectIncorrect - Question 11 of 60
11. Question
Smoking cigarettes causes a speeding up in the rate of blood flow, which in turn increases the risk of heart disease. It was thought that this speeding up of blood flow was caused solely by the gas carbon monoxide, which is absorbed during smoking, and not by nicotine, which is also absorbed from the smoke in the lungs. However, tests have shown that using nicotine patches (from which nicotine is absorbed through the skin) or chewing nicotine gum also causes the rate of blood flow to increase. This shows that the nicotine in cigarettes is also responsible for the increased risk of heart disease among smokers.
Which one of the following is not an assumption of the argument in the passage above?
CorrectIncorrect - Question 12 of 60
12. Question
In many countries shocking images of the damage smoking can do to the body are displayed on cigarette packets. Images of rotting teeth, mouth tumours and cancerous lungs are among the grim pictures. A review concluded that shocking pictures of the damage smoking can do are a cost effective way to help smokers to quit and discourage others from starting. All countries should introduce these kinds of images to discourage smoking.
Which one of the following, if true, most weakens the above argument?
CorrectIncorrect - Question 13 of 60
13. Question

For customers buying coffee this week, which of these bar graphs shows how the average cost per jar (as a percentage of the normal cost) varies with the number of jars bought?
CorrectIncorrect - Question 14 of 60
14. Question
During a recent storm, the plastic company logo fell off the outside of the office building of Fleesam Ltd. and broke cleanly into the two pieces shown below:

Which one of the following could not be Fleesam’s logo?
CorrectIncorrect - Question 15 of 60
15. Question
A golf tournament is played over 10 rounds, on successive Saturdays. The winner of each round scores 3 points and the player finishing second scores 1 point. The tournament is won by the competitor with the most points over the 10 rounds.
Alan Vinci, Barry Durand, Carl Johansson, and Daniel and Eric Lim were the participants in this year’s tournament.

20. Question
Last month Karl walked from Starton to Endham, raising money for charity. His target, successfully achieved, was to complete the walk in ten days.
He started later than intended and had only completed 12 km by the end of the first day. However, he walked 45 km on each of the second, third, and fourth days, and after the fifth day he was exactly halfway. Poor weather on the sixth day restricted his progress, but 41 km on both the seventh and eighth days meant that he had completed exactly three-quarters of the walk with two days left. On the ninth day he covered three-fifths of the remaining distance, completing the last 36 km on the tenth day.
How far did Karl walk from Starton to Endham?
