5. Many geologists theorize that the trail of volcanic craters and cinder cones along the Snake River plain of southern Idaho was produced as the North American continent slid westward over a stationary "plume," a vertical channel through which molten rock rose intermittently from the Earth's core to burst through its crust.



Which of the following, if true, tends to support the geologists theory of how the trail was produced?


(A) The largest craters and cinder cones are on the eastern margin of the trail.
(B) The most violent volcanic activity apparently occurred at the western margin of the trail.
(C) The craters and cinder cones are evenly spaced throughout the entent of the trail.
(D) The newest craters and cinder cones are on the eastern margin of the trail.
(E) The craters and cinder cones on the western margin of the trail generally took longer to form than did those on the eastern margin.

这个题我曾经听其他人解释过，关键要看清提干中的原理解释，是向西移动，通过那个喷涌的通道，画一张图就可以看出，一开始喷出的就跟着板块向西移动了，所以D最新的在东边就成立了

15. The dramatic rise in the number of homeless people in the 1980's cannot be attributed to the discharge of mentally ill persons from hospitals into "community care." even though it is true that provisions for such community care are for the most part nonexistent.



Which of the following , if true, best supports the claim above?


(A) the policy of discharging mentally ill persons from hospitals was based on the supposition that their illnesses could be controlled by newly developed drugs.


(B) Without supervision in a hospital setting those people whose mental illness can be controlled by medication might not actually take prescribed medicaiton.


(D) The policy of discharging significant numbers of mentally ill persons from hospitals took effect in the 1960's.

我觉得D的感觉就是建立桥梁联系吧，先否定题干结论，是the discharge of mentally ill persons from hospitals into "community care.     if ture的话，1960's的流离失所的人应该也很多，但事实相反。所以D比较合适。
B选项好像是说“在医院里没有指导管理地安置那些可能通过药物控制的而没有真正得到应该的治疗的人”，有削弱的感觉，Without supervision ,没有预期的治疗，那的确造成了这些人出院后的出走
