Questions –13 The correct answer is false

C and E are not correct:
Sections C and E mention trade but do not give any 
examples of items.
19 The correct answer is B: 
The text says, ‘glacial archaeologists need to race the clock to find 
newly revealed artefacts, preserve them, and study them’. The idiom ‘race against the clock’ 
refers to the pressure to do something quickly before time runs out. The text then gives two 
examples explaining why they have to work quickly: ‘If something fragile dries and is windblown 
it might very soon be lost to science, or an arrow might be exposed and then covered again by 
the next snow’. 
C is incorrect:
Section C refers to how hard archaeologists’ work can be, but 
makes no mention of the pressure to work quickly.
20 The correct answer is ‘microorganisms’ or ‘micro-organisms’: 
In Section B, the text says, 
‘Organic materials like textiles and hides are relatively rare finds at archaeological sites. This is 
because unless they’re protected from the microorganisms that cause decay, they tend not to 
last long.’ The term ‘hides’ is another word for animal skins.

The word ‘congregated’ means came together in groups, so has a similar meaning to gathered. 
‘
Insects’ is incorrect:
The text does not say that the insects were trying to avoid anything
. 
‘Hunters’ is incorrect:
The text does not say that hunters gathered or that they were trying to 
avoid anything.
