What this part tests
This part is tested with Note Completion (Q31–40). Each section below gives the strategy for that question type, the answers, and the sentence that proves them.
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.
“because of the world’s increasing population and expanding industry.”
Demand grows because of 'the world's increasing population and expanding industry', so 'industry' fits.
“This form of energy has plenty of potential, as the source is constant”
The energy has potential because 'the source is constant', so that adjective describes the supply.
“But the problem with ocean waves is that they’re erratic, with the wind making them travel in every direction.”
Waves are erratic because the wind makes them 'travel in every direction', so 'direction' fits.
“Another drawback is that sand and other sediment on the ocean floor might be stopped from flowing normally”
Sediment on the 'ocean floor' might be stopped from flowing, so 'floor' completes the phrase.
“One major advantage of using the tide, rather than waves, as a source of energy is that it’s predictable”
The major advantage of tidal energy is that 'it's predictable', so that adjective fills the gap.
“This will be an area of water within a bay at Swansea, sheltered by a U-shaped breakwater, or dam, built out from the coast.”
The water area lies 'within a bay at Swansea', sheltered by a U-shaped breakwater.
“Then, in order to release the stored water, gates in the breakwater are opened.”
Stored water is released when 'gates in the breakwater are opened', so the plural 'gates' fits.
“the turbines are operated without the need for fuel”
The turbines run 'without the need for fuel', so 'fuel' is what is not required.
“that manufacturing the components would create more than 2,000 jobs, a big boost to the local economy.”
Manufacturing would 'create more than 2,000 jobs', so the plural noun 'jobs' fits.
“On the other hand, there are fears that lagoons might harm both fish and birds, for example by disturbing migration patterns”
Lagoons might harm fish and birds by 'disturbing migration patterns', so 'migration' fills the gap.
