Task №7
... Those who regularly took 30-minute naps were more than twice as likely to remember simple words such as those of new toys than their non-napping counterparts ...
If in 100 toddlers 5% who did not nap were able to remember a new teddy’s name, how many who had napped would be expected to remember?
The answer is 12 because more than twice means the number of toddlers is >5%×2.
Task №14
‘We should allow people to drive as fast as they want. By allowing drivers to drive at fast speeds, through natural selection the most dangerous drivers will kill only themselves in car accidents. These people will not have children, hence only safe people will reproduce, and eventually the population will only consist of safe drivers.’ Which one of the following, if true, most weakens the above argument?
Which one of the following, if true, most weakens the above argument?
Dangerous drivers harm others more often than themselves by driving too fast.
Dangerous drivers may produce children who are safe drivers.
The answer is 1. The idea of the passage is mostly based on the hypothesis that drivers harm only themselves, so only fast drivers will die. Even if answer 2 is right and first is true, the world would be safe from fast drivers by suicidal accidents, because it does not hurt others.
Task №16
Sadly the way in which children interact with each other has changed over the years. Where once children used to play sports and games together in the street, they now sit alone in their rooms on the computer playing games on the internet. Where in the past young children learned human interaction from active games with their friends this is no longer the case. How then, when these children are grown up, will they be able to socially interact with their colleagues?
Which one of the following is the conclusion of the above statement?
Children who play computer games now interact less outside of them.
Children should be made to play outside with their friends to develop their social skills later in life.
The answer is 1. All that because 1st entirely relates to the passage, while 4th answer is considered as the solution.
