1. In some countries, prisoners may purchase books with the money they earn by working. Hence receiving gifts of books may discourage prisoners from undertaking paid work while in prison.

This work is important in building self-esteem and encouraging a work ethic among prisoners. In any case, prisoners have access to books through the prison library. Therefore, prisoners should not be allowed to receive parcels containing books from friends or relatives while they are serving their sentence.

2. Thousands of books and blogs – and quite a bit of legitimate science – sing the praises of
positivity. Optimistic, happy people tend to be healthier, more physically active and more
successful. They may even live longer. But as shown by research, positivity, when deployed at
the wrong time or in the wrong amount, can have negative effects. For example, when it comes
to waiting for the results of an exam or a job interview, ‘being prepared for the worst’ is shown to
be a better strategy for protecting ourselves than categorical optimism. When it comes to
health, negative thinking spurs people into seeking information and engaging in healthy
behaviour. Finally, relentlessly positive people may seem dismissive or insensitive to friends
who are having difficulties, seeming to make light of their problems.
Which one of the following best expresses the main conclusion of the above argument?

3. A piece of paper is laid on a table in landscape orientation (i.e. the longer side running left to right
and the shorter side running top to bottom).
This piece of paper is then folded in half four times, alternately by moving the left hand side
across over the right hand side and folding, and by moving the top half down over the bottom
half and then folding. After each fold a dot is made with a pen in the centre of the face showing
on the table.
After the four folds and four dots, the paper is unfolded in the reverse sequence and is then
turned over so that the four dots are showing.
What is the pattern of the dots on the paper? (Dotted lines represent the fold marks)

4. As part of a maths project, a class of 30 children conduct a survey amongst themselves of how
many brothers and sisters they have. They each write their name in the appropriate space on
the chart below. No one in the class has a brother or sister who is also in the class.

6. LoCost sells three different types of washing powder: Zoom, Zap and Ownbrand. Zoom is a
double concentrate brand needing only half the amount of powder used by the other two brands.

7. In 1938 the Dutch artist Piet Mondrian left Paris to escape the threat of German invasion and
went to live in London, where he painted what are now regarded as his best works. Mondrian
had the option of moving to a more rural area in England, but chose London because of his love
of the diverse and vibrant culture of big cities. This explains why London has more artists living
in it than any other city in England.
Which one of the following is an underlying assumption of the above passage?

9. Jeff is looking to buy a new car. He will only be using it for commuting to his workplace for 1 year and will have a total annual mileage of 20000. He wants to buy the car which would make his total spend over the year, including the initial cost of the car, the lowest.

10. Although the idea of a driverless vehicle seems like the stuff of science fiction, we are moving very close to the reality of self-driving cars. But we are so engrossed in the technology that we are ignoring the legal implications – and legislating for new scenarios takes time. A whole new set of questions is raised by the development of these machines. One example is the question of who takes responsibility when an accident happens. Given that the vast majority of crashes are caused in part at least by human error, self-driving cars should have the capacity to save lives. But they will not be perfect. So if an accident happens, who is responsible? The owner of the car, or the manufacturer of the car? The car itself cannot be prosecuted or made to pay damages.
