Questions 27–40
27 The correct answer is NOT GIVEN: 
In Section A, the text refers to the Cambridge scientists’ 
discovery and the publication of their findings, but does not mention other scientists’ reaction
to this.
28 The correct answer is TRUE: 
In Section D, Dr Philip Wigge refers to the target for 2050 and 
then says, ‘but climate change is a major threat to achieving this.’ If there is a major threat to 
achieving something, this means that it might not be achieved.
29 The correct answer is TRUE: 
In Section D, the text says, ‘Key crops such as wheat and rice 
are sensitive to high temperatures. Thermal stress reduces crop yields by around 10% for every 
one degree increase in temperature’. If crop yields are reduced, this means that the crops suffer 
when temperatures increase.
30 The correct answer is NOT GIVEN: 
There is no mention of the possibility of developing 
crops that require less water.
31 The correct answer is FALSE: 
In Section E, the text says, ‘During the day, sunlight activates 
the molecules, slowing down growth. If a plant finds itself in shade, phytochromes are quickly 
inactivated – enabling it to grow faster to find sunlight again.’ This means that plants grow more 
slowly in sunlight than in shade.
