Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour’s flight one of the scientists wrote in his book, "Look here for probable metal. " Scientists in another airplane, flying over a mountain area, sent a message to other scientists on the ground, "Gold possible. " Walking across hilly ground, four scientists reported. "This ground should be searched for metal." From an airplane over a hilly wasteland a scientist sent back by radio one word: "Uranium."

None of the scientists had X-ray eyes: they had on magic powers of looking down below the earth’s surface, They were merely putting to use one of the newest methods of locating minerals in the ground, using trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing.

This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface.

At Weston Bar Greek, a brook six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.

Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches.

Which of the following is not mentioned as part of tree that can help find minerals()

A．Leaves.

B．Roots.

C．Branches.

D．Seeds.

赵村与吴村毗邻，吴村的用水取自流经赵村的小河，多年来两村经常因用水问题发生冲突。2001年春，为根本解决问题，县政府决定将这条小河的水流交给乡水管站统一调配。赵村人认为：小河历史上就属于赵村所有，县政府无权将这条河的水流交乡水管站统一调配，遂将县政府告上法院。请问：根据现行宪法和法律，下列哪一说法是正确的

A．赵村告得有理，因为水流属于村民集体所有，政府无权收归国有

B．赵村告得有理，因为这条小河的河床届于赵村集体所有，这条小河里的水流当然也属于村民集体支配

C．县政府的决定合法，因为水流属于国家所有，政府当然有权调配河水的供应

D．县政府的决定合法，因为水流虽然居于赵村所有，但吴村人也应享有喝水用水的权利，为解决吴村用水问题，政府可以将水流供应统一调配
