 I You will listen to a brother and sister discuss a natural phenomenon. As 
you 	listen, 	 mark 	the 	four 	 true 	statements 	 from 	1–6 	 given 	 below.
Brother	 : 		 I 	 liked 	 the 	 pictures 	 Uncle 	 Dileep 	 posted 	 yesterday 	
from 	 the 	 Republic 	 of 	 Peru. 	 Can 	 you 	 guess 	 which 	 was 	
my 	favourite?
Sister	 : 		 I 	 know 	 it 	 was 	 the 	 Rainbow 	 Mountain. 	 I 	 say 	 that 	
because 	it 	was 	 certainly 	 my 	 favourite.
Brother	 : 		 Really! 	 I 	 didn’t 	 know 	 it 	 was 	 your 	 favourite 	 too. 	
Can 	 you 	 imagine 	 the 	 creativity 	 in 	 Nature? 	 What 	 a 	
marvellous 	 natural 	 phenomenon!
Sister	 : 	 	 I 	 could 	 not 	 believe 	 my 	 eyes 	 when 	 I 	 saw 	 that 	 picture. 	
There 	 are 	 so 	 many 	 colours 	 there. 	 Do 	 you 	 know 	 how 	
it’s 	 formed?
Brother	 : 	 	 Of 	 course! 	 It’s 	 actually 	 quite 	 amazing. 	 The 	 mountain 	
gets 	 its 	 colours 	 from 	 layers 	 of 	 minerals 	 like 	 clay,	
limestone, and sandstone that got deposited millions 
of 	 years 	ago.
Sister	 :  Wow, I read that too. I think each colour is due to a 
di??erent 	 mineral. 	 Like, 	 the 	 green 	 comes 	 from 	 copper, 	
and 	 the 	 red 	 from 	 clay. 	 It’s 	 like 	 nature 	 painted 	 the 	
mountain!

Brother	 :  I cannot believe the fact that it was all buried under 
snow 	 until 	recently. 	
Sister	 : 	 	 Oh! 	 The 	 melting 	 snow 	 must 	 have 	 made 	 it 	 visible 	
again. 	That’s 	why 	 it 	 looks 	 so 	fresh 	 and 	 bright 	today. 	
Brother	 : 		 Those 	 layers 	 of 	 minerals 	 were 	 actually 	 deposited 	 by 	
water from ancient seas and lakes. 
Sister	 : 	 	 Each 	 colour 	 represents 	 a 	 di??erent 	 time 	 in 	 history. 	
That’s 	 why 	it’s 	 called 	 the 	rainbow 	mountain.
