Practice Module 8
Question 1
Flag this item
“The traditional school sports day – featuring races with clear winners and losers – is being
replaced in some schools by “fun days” of non-competitive games. The rationale for this is
that the self-esteem of children who always lose in competitive races is damaged. But in adult
life, competition for jobs, partners and social status is unavoidable. Schools should recognize
this and revert to traditional sports days.”
1. Which one of the following is an assumption of the
above argument?
2.
Children are not naturally competitive.
Children who lose competitive races will be unsuccessful in adulthood.
Non-competitive games boost children’s self-esteem.
School sports should prepare children for adult life.
Correct Answer: D
Explanation:
The conclusion of this argument is that ‘schools should revert to traditional sports day’ and
the evidence is that ‘adult life involves competition’. To link this evidence to the conclusion
the assumption is that school sports should not prepare children for adult life. None of the
others are assumptions to be made, and A&B are not relevant to the argument.
Question 2

To pass the time on a long car journey, two children were playing a counting game. Julia
counted the number of animals they saw, and Tim counted their legs. After 15 minutes, all
they had seen was birds and sheep. Julia had counted 13 animals and Tim had counted 36
legs.
2. How many sheep had they seen?
3.
4
, 5
6
8
10
Correct Answer: B
Explanation:
Julia counted the animals – b+s =13.
Tim counted the legs (birds have 2, sheep have 4) – 2b+4s=36.
Solving these gives us s=5, b=8.
Question 3

I have an electronic device which, on the press of a button, generates a number between 1 and
6. It is supposed to generate numbers randomly, but I have noticed that it generates numbers
in groups of four that always add up to 14, and it never generates more than five consecutive
odd numbers or even numbers.
In the game I am currently playing using this device, the last fifteen numbers (in order from
earliest to latest) have been:
.....344241562425355
3. What number will appear next?
4.
1
2
3
4
Correct Answer: B
Explanation:
, First, we need to find the groups of 4 that add up to 14. The first is that is fully available is
4,4,2,4, next is 1 5 6 2, next is 4 2 5 3 and finally 5 5. The next 2 numbers must add to 4, so 4
is not viable. If it were 1 or 3, there would have been 5 consecutive odd numbers, which is
not possible. Thus, 2 is the only possible answer.
Question 4

“The UK government is committed to economic growth of 2% per year. If this goal is
achieved, energy consumption in the UK will have doubled by 2050. The government is also
committed to a huge reduction in carbon emissions by 2050. If energy consumption has
doubled, this would require a massive increase in energy from sources other than fossil fuels,
i.e. from nuclear power or from renewables such as wind, tidal and solar power. At the
present rate of development of wind, tidal and solar power, these sources will be unable to
meet the shortfall in supply. So, although nuclear power is seen as problematic because it
produces dangerous waste, it will have to continue to be used in 2050.”
4. Which of the following identify/identifies a weakness
in the above argument?
1. The government’s goal for economic growth may not
be achieved.
2. By 2050 we may have discovered how to store nuclear
waste safely.
3. It may be possible to speed up the development of
renewable energy sources.
4.
1 only
2 only
3 only
1&2
1&3
2&3
Correct Answer: E
Explanation:
, 1 is correct as the conclusion is that ‘nuclear power…will have to continue to be used in
2050’ and the evidence is that energy consumption will reach the target and be very high at
this point, but to link these two we need the assumption that the energy consumption will
actually be that high in 2050.
Question 5

A corner shop is selling biscuits at 4 packs for the normal price of 3. At this price, the
shopkeeper is making 20% profit.
5. What percentage profit does she make when selling the
biscuits at the normal price?
6.
25%
26.7%
33.3%
60%
75%
Correct Answer: D
Explanation:
The shopkeeper buys 4 packets(4p) and sells them for the price of 3 packets (3y) and gains
20% profit. Thus, 3y/4p=1.2, which we can rearrange to get y=1.6p. This, there is 60% profit
made.

In the main draw of the National Lottery six different numbers between 1 and 49 inclusive
are selected at random live on television. My sister and I both buy a ticket every week.
Whenever one of us is not able to watch the draw the other texts the numbers the instant the
sixth one is revealed.
e.g. 15, 46, 20, 31, 5, 22
One week however, my sister forgot to leave gaps between the numbers and I received the
following:
3437427337
