Conservationists have believed that by concentrating their preservation efforts on habitats rich in an easily surveyed group of species, such as birds, they would thereby be preserving areas rich in overall species diversity.

Which of the following findings about widely scattered tracts 10 kilometers by 10 kilometers in a temperate climate zone would most seriously challenge the conservationists’ assumptions（）
A. The tracts show little damage from human intrusion and from pollution by human activities

[单项选择]People once widely believed that intelligent life existed on Mars. The 19th-century discovery of what appeared to be geometric designs cut across the surface was taken as evidence. The lines were thought to have been a system of canals that had been built to irrigate the surface. It is now clear that the "canals"—perhaps the most spectacular geologic features of Mars—are natural valleys where ancient rivers once flowed.
Another fragmented idea concerns the planet’’s seasonal changes in color. Once attributed to the rapid spread of some life-form, these shifts are now known to develop from the movement of fine dust in the atmosphere.
By the close of the 20th century none of the many experiments conducted by spacecraft had ever found persuasive evidence of life. Nevertheless, speculation continued over the existence of some form of life, in either the present or past. In 1996 scientists discovered organic compounds and minerals in a meteorite (陨石), consisting of Martian rock, t
A. Because the surface of Mars seemed to be geometric.
B. Because the lines were drawn across the surface of the planet.
C. Because a system of canals was thought to be there.
D. Because it was the Martians that built the canals.
