各位大虾, 有几道GWD的CR一直困扰着小弟, 麻烦各位帮忙看看....谢谢.
A theory is either true or false. Galileo's observations of Jupiter's satellites showed that the Ptolemaic theory of the motion of celestial bodies is false. Therefore, since the Copernican theory of planetary motion is inconsistent with the Ptolemaic account, Galileo's observations of Jupiter's satellites proved the truth of the Copernican theory.
The argument above is open to the objection that it makes the questionable assumption that
A. Whoever first observed something inconsistent with the truth of the Ptolemaic theory should be credited with having proved that theory false.
B. There are some possible observations that would be inconsistent with the account given by the Copernican theory but consistent with the account given by the Ptolemaic theory.
C. The Ptolemaic and Copernican theories, being inconsistent, cannot both be based on exactly the same evidence
D. Numerous counterexamples were necessary in order to show the Ptolemaic theory to be false
E. The Ptolemaic and Copernican theories, being inconsistent, cannot both be false.
question: 请问如何理解open to the objection? 题目是否问原文的错误前提是什么?

In 1992 outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the country of Belukia. Soon after, the annual tonnage of lobster legally harvested in Belukian waters began declining; in 1996, despite there being no reduction in the level of legal lobster fishing activity, the local catch was 9,000 tons below pre-1992 levels. It is therefore highly likely that the outlaw fishing boats harvested about 9,000 tons of lobster illegally that year.
Which of the following is an assumption on which the argument depends?
A. The illegal lobster harvesting was not so extensive that the population of catchable lobsters in Belukia's territorial waters had sharply declined by 1996
B. The average annual lobster catch, in tons, of an outlaw fishing boat is has increased steadily since 1992.
C. Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats.
D. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons.
E. A significant proportion of Belukia's operators of licensed lobster-fishing boats were out of business between 1992 and 1996

Consumers planning to buy recreational equipment tend to buy higher quality, more expensive equipment when the economy is strong than when it is weak. Hill and Dale is a business that sells high-quality, expensive camping and hiking equipment in Boravia. Although all the signs are that Boravia'seconomy is now entering a period of sustained strength, the managers of the business do not expect a substantial increase in sales.
Which of the following, if true, would provide the strongest justification for the managers' judgment?
A. A significant proportion of Hill and Dale's sales are made to customers who enter the store in order to buy one particular item but, once there, find other items to buy as well.
B. In Boravia when the economy is strong, those who might otherwise go camping tend to take vacations overseas.
C. The economic upturn is likely to allow Boravia's national parks, where most of the camping and hiking is done, to receive extra funding to improve their visitor facilities.
D. Advances in materials technology have led to the development of hiking and camping equipment that is more comfortable and lightweight than before.
E. Many people in Boravia not only are committed to preserving the country's wilderness areas but also are interested in spending some time in them.
Remark: 在B,C之间徘徊很久, B没有错, 但觉得C也没有错啊. WHY? 大多数的camping, hiking都在那里, 而国家公园又改善了它们的设施. 那么人们需要购买的需求当然也就减少了呀.

The Hyksos invaded the Nile Delta of Egypt and ruled it from 1650 B.C. Their origin is uncertain, but archaeologists hypothesize that they were Canaanites. In support of this hypothesis, the archaeologists point out that excavations of Avans, the Hyksos capital in Egypt, have uncovered large numbers of artifacts virtually identical to artifacts produced in Ashkelon, and Ashkelon was a major city of Canaan at the time of the Hyksos' invasion.
In order to evaluate the force of the archaeologists' evidence, it would useful to determine which of the following?
A. Whether artifacts from Ashkelon were widely traded to non-Canaanite cities?
B. Whether significant numbers of artifacts that do not resemble artifacts produced in Ashkelon have been found at Avans?
C. Whether Avans was the nearest Hyksos city in Egypt to Canaan?
D. Whether Ashkelon after 1550 B.C. continued to produce artifacts similar to those found at Avans?
E. Whether any artifacts produced by the Hyksos after 1550 B.C .have been found in Egypt
