Questions 14-19
Choose heading v because Section A gives two clear educational goals: "First, it is intended to show visitors how extraordinary coral reefs are" and "Second, it draws attention to the research and conservation work now being undertaken to protect reefs from global warming."
Associated Text:
First, it is intended to show visitors how extraordinary coral reefs are, since they are the most diverse ecosystems on the planet. Second, it draws attention to the research and conservation work now being undertaken to protect reefs from global warming, so that the public can see practical efforts to save them.
Choose heading ii because Section B describes cooperation between coral polyps and algae: "The algae receive protection there, while their photosynthesis supplies nutrients to the polyps."
Associated Text:
The algae receive protection there, while their photosynthesis supplies nutrients to the polyps.
Choose heading iv because Section C reports disagreement about the phrase "rainforests of the sea": "reefs are often called the rainforests of the sea, although some naturalists, among them David Attenborough, reject the comparison."
Associated Text:
Because of this richness, reefs are often called the rainforests of the sea, although some naturalists, among them David Attenborough, reject the comparison.
Choose heading vii because it gives the main idea of the paragraph. The supporting evidence is: "Large areas, including major parts of Australia's Great Barrier Reef, have already been lost, and researchers warn that more than 90 percent of reefs could disappear by 2050 unless greenhouse gas emissions and global heating are addressed rapidly.". This sentence shows what the paragraph is mainly about, rather than just mentioning a small detail.

Questions 20-21
Choose two letters A-E.
Which TWO of these causes of damage to coral reefs are mentioned by the writer of the text?
(A) is incorrect. Choice A says "An increasing frequency of severe storms.", but the supporting evidence for the correct answers is "Further threats include ocean acidification, rising sea levels, pollution by humans, deoxygenation and changes in ocean currents, while the climate crisis is also worsening habitat destruction. Further threats include ocean acidification, rising sea levels, pollution by humans, deoxygenation and changes in ocean currents, while the climate crisis is also worsening habitat destruction.". That evidence does not give Choice A as one of the two required statements.
(B) is incorrect. Choice B says "Taking excessive numbers of fish from the sea.", but the supporting evidence for the correct answers is "Further threats include ocean acidification, rising sea levels, pollution by humans, deoxygenation and changes in ocean currents, while the climate crisis is also worsening habitat destruction.

That evidence does not give Choice B as one of the two required statements.
(C) is correct. Choice C matches the question because "Pollution of seawater by waste." is directly supported by the passage evidence: "Further threats include ocean acidification, rising sea levels, pollution by humans, deoxygenation and changes in ocean currents, while the climate crisis is also worsening habitat destruction.". That sentence gives one of the required ideas for "Which TWO of these causes of damage to coral reefs are mentioned by the writer of the text?".
(D) is incorrect. Choice D says "A rise in illness among marine species.", but the supporting evidence for the correct answers is "Further threats include ocean acidification, rising sea levels, pollution by humans, deoxygenation and changes in ocean currents, while the climate crisis is also worsening habitat destruction. Further threats include ocean acidification, rising sea levels, pollution by humans, deoxygenation and changes in ocean currents, while the climate crisis is also worsening habitat destruction.". That evidence does not give Choice D as one of the two required statements.
(E) is correct. Choice E matches the question because "Changes to the normal movement of seawater." is directly supported by the passage evidence: "Further threats include ocean acidification, rising sea levels, pollution by humans, deoxygenation and changes in ocean currents, while the climate crisis is also worsening habitat destruction.". That sentence gives one of the required ideas for "Which TWO of these causes of damage to coral reefs are mentioned by the writer of the text?".
