单选题 In the world of art, distinguishing the authentic piece from the forgery is not an easy feat and often requires the use of multiple experts. Millions of dollars can be at stake, yet even experts can be fooled. However, a recent discovery has introduced a new resource for galleries and other groups seeking to establish the origins of their paintings: mathematicians. Math experts were able to analyze digital images of authenticated paintings where they found consistent differences in paint texture. This consistency suggests that each artist has a unique style of brush stroke that cannot be completely duplicated. In the first two sentences of the passage, the author suggests which of the following?

A. It is nearly impossible to determine whether a painting is authentic or fake without the use of math.
B. Even if multiple experts from various fields analyze a painting, it is not always possible to determine its authenticity.
C. New discoveries in art always lead to a greater degree of truth.
D. Art can be difficult to analyze, but mathematical models can help to find the truth.
E. Mathematicians have a great degree of expertise in analyzing art.

【正确答案】 B

【答案解析】The first two sentences tell the reader that even multiple experts can be fooled into believing that a forged painting is authentic. This thought best matches choice B.

单选题 In many Western European nations, the law is seen as rigid and not open to interpretation. This rigidity grants a consistency to questions of law that many would argue is absent in other, more flexible systems. The European construction of law provides litigants with a clear picture of how a case will be decided. All parties involved are certain how judges will rule on issues. It is simple--judges will strictly follow the law. This simple fact, that the law will not change from one situation to another, allows for court systems in Western Europe to process cases efficiently and cuts down on the amount of frivolous lawsuits. It is useless for an individual to attempt a case if he knows in advance that the law is not in his favor. In the passage, the author is primarily concerned with

A. arguing for a universal application of Western European legal practices
B. decrying the rigidity and constancy of Western European legal practices
C. describing the potential benefits of Western European legal systems
D. defining the pros and cons of various legal systems
E. denouncing European law for its anti-consumer bias

【正确答案】 C

【答案解析】The adjectives "efficiently" and "frivolous" indicate that the author approves of Western European legal systems. This supports choice C. The verbs in choices A, B, and E all connote the wrong tone.
