According to the passage, all of the following have caused damage to the paintings EXCEPT _______ A. water B. temperature changes C. air movement D. light

Đáp án A

D. light

Unfortunately, the paintings have been exposed to the destructive action of water and temperature changes, which easily wear the images away. Because the Lascaux caves have many entrances, air movement has also damaged the images inside. Although they are not out in the open air, where natural light would have destroyed them long ago, many of the images have deteriorated and are barely recognizable.
