Questions 31–40: Note Completion
Strategy: Predict the word class from the note, find the paraphrase of the note's keyword in the transcript, then copy the answer exactly within the word limit.
“One species which is well known as being highly adaptable is the crow, and there’ve been various studies about how they manage to learn new skills”
The species described as 'highly adaptable' and able to learn new skills is 'the crow'.
“the pigeon, because they’re able to perch on ledges on the walls of city buildings, just like they once perched on cliffs by the sea.”
Pigeons perch on city ledges 'just like they once perched on cliffs by the sea', so 'cliffs' fits.
“And one thing that researchers are finding especially interesting is the speed with which they’re doing this – we’re not talking about gradual evolution here – these animals are changing fast.”
Researchers find 'the speed' with which animals change interesting, since it is not gradual evolution.
“And she found that during that time, these small mammals had experienced a jump in brain size when compared to rural mammals.”
The small mammals showed 'a jump in brain size', so the gap needs 'brain'.
“And Snell-Rood thinks that this change might reflect the cognitive demands of adjusting to city life – having to look in different places to find food, for example, and coping with a whole new set of dangers.”
Adjusting to city life means looking 'in different places to find food', so 'food' fits.
“there’s another biologist called Catarina Miranda who’s done some experiments with blackbirds living in urban and rural areas. And she’s been looking not at their anatomy but at their behaviour.”
Miranda looked 'not at their anatomy but at their behaviour', so 'behaviour' fills the gap.
“But there’s one type of situation that does seem to frighten the urban blackbirds, and that’s anything new – anything they haven’t experienced before.”
The only thing that frightens urban blackbirds is 'anything new', so the adjective is 'new'.
“He’s found that when they’re under stress, their endocrine systems react by reducing the amount of hormones such as corticosterone into their blood.”
When the birds are 'under stress', hormone levels drop, so the gap needs 'stress'.
“they’ve been looking at how squirrels communicate in an urban environment, and they’ve found that a routine part of their communication is carried out by waving their tails.”
Squirrels communicate by 'waving their tails', so the singular 'tail' fits the note.
“One possibility is that we may see completely new species developing in cities. But on the other hand, it’s possible that not all of these adaptations will be permanent”
The speaker doubts that all these adaptations will be 'permanent', so that adjective fills the gap.
