Questions –13 The correct answer is false

6 The correct answer is FALSE: 
The text refers to the period which female polar bears spend 
in their den over the winter and then says, ‘Despite this, their bones remain strong and dense’. It 
also refers to Lennox and Goodship’s findings that ‘six months later, when they finally emerged 
from the den with their cubs, there was no evidence of significant loss of bone density’.
7 The correct answer is TRUE: 
The text says, ‘If the mechanism of bone remodelling in polar 
bears can be understood, many bedridden humans, and even astronauts, could potentially 
benefit.’ These are two examples of groups of people who could benefit from scientific 
developments based on the polar bear’s mechanism for increasing bone density.

8 The correct answer is ‘violent’: 
The text says, ‘Bears … seem to be perceived as stupid and 
in many cases violent.’ 
9 The correct answer is ‘tool’: 
The text says, ‘A male bear called GoGo in Tennoji Zoo, Osaka, 
has even been observed making use of a tool to manipulate his environment. The bear used 
a tree branch on multiple occasions to dislodge a piece of meat hung out of his reach.’ The 
second sentence adds information to the first, specifying what the tool was and how the bear 
manipulated his environment; it explains that that the ‘tool’ mentioned in the first sentence was a 
‘tree branch’.
10 The correct answer is ‘meat’: 
The text says, ‘A male bear called GoGo in Tennoji Zoo, 
Osaka, has even been observed making use of a tool to manipulate his environment. The bear 
used a tree branch on multiple occasions to dislodge a piece of meat hung out of his reach.’ The 
word ‘dislodge’ has a similar meaning to ‘knock down’ in this context: the bear used the branch 
to reach upwards and knock the piece of meat out of the tree.
