1.Because of strong overall stylistic similarities, prehistoric cave paintings in El Castillo, Spain and others in Altamira, Spain, were thought to date from the same period. Recent pigment analyses, however, established the Altamira paintings as by far the older and as about the same age as a third group of paintings done in a different overall style. Nevertheless, this case does not prove that stylistic similarities cannot be a reliable indicator of closeness in age, since ____________.
Which of the following most logically completes the passage?
A. experts who knew the results of the pigment analyses reexamined these paintings and found no previously unnoticed stylistic similarities between the Altamira paintings and the paintings in the third group
B. there are certain stylistic features that the Altamira paintings share with all known paintings of their period and do not share with the El Castillo paintings
C. before dating by pigment analysis was widely practiced, stylistic similarities were the only means of determining whether two prehistoric cave paintings dated from the same period
D. determining the age of a prehistoric cave painting simply by reference to the age of the pigments used in that painting substitutes technology for artistic judgment
E. there are experts who maintain that the results of the recent pigment analyses leave the striking stylistic similarities between the El Castillo paintings and the Altamira paintings unexplained
答案给的是B,可是我根本就不明白为什么选这个,能解释下么?文中说颜料的分析不能否认stylistic similarity的作用,那为什么不能直接否定掉颜料分析的作用来证明stylistic 的作用么,感觉E也可以啊
2.The Rivera Art Museum recently began charging admission. The resulting decline in visitors has been far larger than at other local museums, which have also begun charging admission. The magnitude of the decline might be due to the Rivera's location near government offices. Because an admission charge is most discouraging to those who plan a short visit, it is likely that government workers who formerly made brief visits during lunch time and after work now do not.
Which of the following would most seriously undermine the proposed explanation?
B. The Rivera does not keep track of how long individual visitors stay in the museum
C. The decline in visitors to the Rivera has been no greater on workdays than it has been on nonworking days.
答案给的是C,但是我觉得B更对啊,如果说博物馆根本不记录游客呆的时间,那它怎么知道是不是官员来玩,那后面的就都不对了
