Part 1 1 D: It is commonly thought that people ‘wilfully’ (consciously,
intentionally) ‘put on’ (pretend to have something they don’t
really have) an American accent when they sing pop music.
2 A: People ‘lapse naturally’ into an American accent; it ‘feels more
natural’; they do it ‘automatically’; it would ‘sound peculiar’ to
sing with their own accent; an American accent is ‘the default’
and it ‘actually requires effort’ not to sing with that accent.
3 C: If something ‘brings shivers to the spine’, it causes a powerful
feeling for a short time, it has a strong emotional effect.
4 D: In ‘just two years’ (only two years, emphasising that this is
a short time), he has progressed from having ‘almost zero
knowledge of music’ to being an exceptional singer, reaching a
very high level on the piano and becoming a very good player
of a range of other instruments, ‘none of which he had
touched’ before.
5 C: The researchers tested what people who had done ‘serial recall’
tasks could remember to see how background music affected
their performance.
6 D: In the tests, people who heard background music did less well
than people who didn’t. This suggests music ‘adversely affects’
(has a bad effect on) performance at work because it is ‘a
distraction’ (it stops people from concentrating properly).
Part 2: Fluttering down to Mexico 7 D: link between ‘these creatures’ and ‘this mass of insects’ in D,
‘butterflies’ and ‘millions of them’ before the gap and ‘They’
after the gap.
8 G: link between ‘Their journey here’ before the gap and the
description of that journey in G.
9 C: link between the butterflies being ‘in search of nectar’ (for food)
and drinking from pools of water before the gap and what they
do after they have therefore ‘Fed and watered’ at the beginning
of C.
10 F: link between beliefs for ‘centuries’ about the arrival of the
butterflies and what was discovered about this more recently,
in the 1970s.
11 A: link between ‘this’ at the beginning of A and the fact that the
migration route is ‘endangered’. The first sentence of A explains
why the migration route is endangered and A gives the results of
this. In ‘This is why’ after the gap, ‘This’ refers to the problems
caused for the butterflies.
12 E: link between ‘these’ at the beginning of E and the four areas of
the reserve that are open to the public mentioned before
the gap.
