Despite the overwhelming scientific proof of the theory of evolution, and even acceptance of the theory by many high-ranking religious ministers, there are still sections of many religions that do not accept evolutions as true. One of the most prominent of these in western society is the Intelligent Design movement, which promotes the religious-based (and scientifically discredited) notion of Intelligent Design as a scientific theory. Intelligent Design proponents often point to complex issues of biology as proof that God is behind the design of human beings, much as a watchmaker is inherent in the design of a watch.

One part of anatomy that has been identified as supposedly supporting Intelligent Design is fingerprints, with some proponents arguing that they are a mark of individualism created by God, with no apparent function except to identify each human being as unique. This is incorrect, as fingerprints do have a well-documented function – namely channeling away of water to improve grip in wet conditions – in which hairless, smooth skinned hands otherwise struggle to grip smooth objects. The individualism of fingerprints is accounted for by the complexity of thousands of small grooves. Development is inherently affected by stochastic or random processes, meaning that the body is unable to uniformly control its development to ensure that fingerprints are the same in each human being. Clearly, the presence of individual fingerprints does nothing to support the so-called-theory of Intelligent Design.

Which of the following best illustrates the main conclusion of this passage?

High levels of alcohol consumption are proven to increase the risk of many non-infectious diseases, such as cancer, atherosclerosis and liver failure. James is a PhD student, and is analyzing the data from a large-scale study of over 500,000 people to further investigate the link between heavy alcohol consumption and health problems. In the study, participants were asked about their alcohol consumption, and then their medical history was recorded. His analysis displays surprising results, concluding that those with high alcohol consumption have a decreased risk of cancer. James decides that those carrying out the study must have incorrectly recorded the data.

Which of the following is NOT a potential reason why the study has produced these surprising results?

The illegal drug cannabis was recently upgraded from a class C drug to class B, which means it will be takenless in the UK, because people will know it is more dangerous. It also means if people are caught, possessingthe drug they will face a longer prison sentence than before, which will also discourage its use.

There has been a recent change in the way the government helps small businesses. Whilst previously small businesses were given non-repayable grants to help them grow their profits, they can now only receive government loans that must be repaid with interest when the business turns a certain amount of profit. The government wants to support small businesses but studies have shown they are less likely to prosper under new scheme as they have been deterred from taking government money for fear of loan repayments.

Which one of the following can be concluded from the passage above?

WilderTravel Inc. is a company which organizes wilderness travel holidays, with activities such as trekking, mountain climbing, safari tours and wilderness survival courses. These activities carry inherent risks, so the directors of the company are drawing up a set of health regulations, with the aim of minimizing the risks by ensuring that nobody participates in activities if they have medical complications meaning that doing so may endanger them. They consider the following guidelines:

‘Persons with pacemakers, asthma or severe allergies are at significant risk of heart attack in low oxygen environments’. People under taking mountain climbing activities with WilderTravel frequently encounter environments with low oxygen levels. The directors therefore decide that in order to ensure the safety of customers on WilderTravel holidays, one step that must be taken is to bar those with pacemakers, asthma orallergies from partaking in mountain climbing.
