Time is represented in an unusual way in Bolandia. The format is mm:hh, where mm 

represents the number of minutes to the next hour (hh). For example, 17:03 represents 17 

minutes before 3am. However, there are still 60 minutes in an hour and 24 hours in a day. 

 

Helen is staying in a hotel in Bolandia, and the clocks in the hotel display time in this way. 

 

When she goes to bed one evening, the clock in her room reads 21:23. She wakes up a while 

later and sees that the clock says 23:04. 

 

For how long has Helen been asleep?

B  1 hour 41 minutes 

 

C  2 hours 19 minutes 

 

D  4 hours 58 minutes 

 

E  5 hours 2 minutes 

 

F  6 hours 14 minutes

Research has shown that parents with high incomes tend to have children who score highly in 

IQ tests. It is very unlikely that this is because having rich parents improves one’s IQ. Much 

more likely is that being intelligent tends to result in having a high income, since a high level of 

intelligence is required for entering well-paid professions such as medicine and law. The 

research did not examine whether the relationship between parental income and children’s IQ 

scores was dependent on the nature of the parents’ profession. If it were found that the 

children of high earners in sport and entertainment did not generally have high IQ scores, we 

could conclude that the intelligence level of children is largely genetically inherited from their 

parents.    

 

Which one of the following is an assumption underlying the above argument? 

 

 

 

A  A high level of intelligence is not required for a career in sport or entertainment. 

 

B  The children of rich parents are likely to have a much better education than others. 

 

C  The children of high earners in sport and entertainment are not likely to have high IQ 

scores. 

 

D  A high level of intelligence guarantees entry to well-paid professions such as medicine and 

law.
