Question 27-29
Reading Passage 3 has eight paragraphs A-H.
Which paragraph contains the following information?
Write the correct letter, A-H, in boxes 27-29 on your answer sheet.
27. Mention of a geo-engineering project based on an earlier natural phenomenon
对应原文：
D.The concept of releasing aerosol sprays into the stratosphere above the Arctic has been proposed by several scientists. This would involve using sculpture or hydrogen supplied aerosols so that sculpture dioxide would form clouds, which would, in turn, lead to a global dimming. The idea is modelled on historic volcanic explosions, such as that of Mount Pinatubo in the Philippines in 1991, which led to a short-term cooling of global temperatures by 0.5℃.Scientists have also scrutinized whether it's possible to preserve the ice sheets of Greenland with reinforced high-tension cables, preventing icebergs from moving into the sea.
原文出现时间的地方描述historic volcanic explosions, such as that of Mount Pinatubo in the Philippines，such as举例子，historic volcanic explosions对应natural phenomenon，因此选D.
