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.
“These hotspots are significant because they allow us to locate key areas for focusing efforts at conservation.”
Hotspots 'allow us to locate key areas for focusing efforts at conservation', so conservation is the effort named.
“The main thing he’d expected to find was that they had very high concentrations of food, but to his surprise that was only true for four of the hotspots – the remaining hotspot was quite badly off in that regard”
Researchers expected 'very high concentrations of food', though only four hotspots showed this, so food is the expectation.
“the water at the surface of the ocean had relatively high temperatures, even when it was cool at greater depths”
The water 'at the surface of the ocean had relatively high temperatures', so surface names the depth.
“because he also found that the water needed to have enough oxygen in it”
The water also 'needed to have enough oxygen in it', so oxygen is the essential gas.
“what she was interested in was marine mammals, things like seals”
She focused on 'marine mammals, things like seals', so mammals is the animal group.
“One thing they found there which stunned other researchers was that there were large numbers of species which live below the ice”
There were 'large numbers of species which live below the ice', so ice is the frozen layer.
“thirdly they calculate the rate at which the decline of the species is happening”
They calculate 'the rate at which the decline of the species is happening', so decline names the fall in numbers.
“For each one they assess, they use the data they collect on that species to produce a map showing its distribution”
Data is used 'to produce a map showing its distribution', so map is the product named.
“In addition, to preserve species such as leatherback turtles, which live out in the high seas but have their nesting sites on the American coast, we need to create corridors for migration, so they can get from one area to another safely”
For turtles they must 'create corridors for migration', so migration is the movement being protected.
“If these commercial fishing boats used equipment which was more selective, so that only the fish wanted for consumption were caught, this problem could be overcome.”
