Questions –13 The correct answer is false

32 The correct answer is FALSE: 
In Section E, the text says, ‘At night, however, it’s a different 
story. Instead of a rapid deactivation following sundown, the molecules gradually change from 
their active to inactive state.’ This means that phytochromes change their state at different 
speeds day and night: in the daytime, they become active or deactivated quickly, depending on 
light levels; by night, they change slowly, depending on temperature.
33 The correct answer is H: 
The text quotes Wigge saying, ‘we have outstanding collaborators 
nearby who work on more applied aspects of plant biology, and can help us transfer this new 
knowledge into the field’. This means that the collaborators’ specialised knowledge of plant 
biology can help the researchers take their findings out of the lab, so that they can be used in 
‘the field’ – a wider, real-world context.
34 The correct answer is D: 
The text quotes Wigge saying, ‘‘Discovering the molecules 
that allow plants to sense temperature has the potential to accelerate the breeding of crops 
resilient to thermal stress and climate change.’ If the researchers’ discovery can speed up the 
development of crops that don’t suffer in rising temperatures, this would be a potential benefit.
35 The correct answer is G: 
The text quotes the well-known rhyme, ‘oak before ash we’ll have 
a splash, ash before oak we’re in for a soak’, followed by Wigge’s explanation about why this 
traditional saying has a scientific basis.

36 The correct answer is C: 
The text says, ‘Farmers and gardeners have known for hundreds 
of years how responsive plants are to temperature: warm winters cause many trees and flowers 
to bud early, something humans have long used to predict weather and harvest times for the 
coming year.’ This sentence mentions trees and flowers budding early as an example of plant 
behaviour, and says that people have long used this as an indication of future conditions: for 
example, in helping farmers to plan when their crops will need to be harvested. If something has 
been known for hundreds of years or if people have ‘long’ done something, this means that it 
has been done ‘traditionally’.
