Elsat test2 sction 4
1. A major art theft from a museum was remarkable in that the pieces stolen clearly had been carefully selected. The criterion for selection, however, clearly had not been greatest estimated market value. It follows that the theft was specifically carried out to suit the taste of some individual collector for whose private collection the pieces were destined.
The argument tacitly appeals to which one of the following principles?
(A) Any art theft can, on the evidence of the selection of pieces stolen, be categorized as committed either at the direction of a single known individual or at the direction of a group of known individuals.
(B) Any art theft committed at the direction of a single individual results in a pattern of works taken and works left alone that defies rational analysis.
(C) The pattern of works taken and works left alone can sometimes distinguish one type of art theft from another.
(D) Art thefts committed with no preexisting plan for the disposition of the stolen works do not always involve theft of the most valuable pieces only.
(E) The pattern of works taken and works left alone in an art theft can be particularly damaging to the integrity of the remaining collection.
总觉得答案D中的sometimes看着不是特别舒服!A不是说受individual的指导,不是何原文一致吗!
2. The teeth of some mammals show “growth rings” that result from the constant depositing of layers of cementum as opaque bands in summer and translucent bands in winter. Cross sections of pigs teeth found in an excavated Stone Age trash pit revealed bands of remarkably constant width except tat the band deposited last, which was invariably that the band deposited last, which was invariably translucent, was only about half the normal width.
The statements above most strongly support the conclusion that the animals died
(A) in an unusually early winter
(B) at roughly the same age
(C) roughly in midwinter
(D) in a natural catastrophe
(E) from starvation
这个猪牙的题我就是根本没有看懂后面的width是什么东西，怎么猪牙又和这个搞到了一起，清高手翻译一下，我看只有看中文了

第一题以前有过讨论, 你找一找.

第二题在于阅读. 某些动物的牙能看到明显的成长环. 其生成的原因是在夏天牙上生成一层不透明的cementum(不用管它什么意思), 冬天生成一层透明的. 某处发掘出来的猪牙表现出这种交错的成长环, 并且各环宽度相当(这是应该想到是因为夏天和冬天的长度相当,各环的生成时间相当), 只是最后一层,也是透明的一环, 宽度只有其它环的一半(说明最后一个冬天里此猪只有一半的时间来生成此环). 答案因此为C.

在阅读过程中要思考, 找到隐含的因果关系.

原来猪牙是这个意思,我明白了,谢谢mindfree bro
