文章：

    In its 1903 decision in the case of Lone Wolf v. Hitchcock, the United States Supreme Court rejected the efforts of three Native American tribes to prevent the opening of tribal lands to non-Indian settlement without tribal consent. In his study of the Lone Wolf case, Blue Clark properly emphasizes the Court's assertion of a virtually unlimited unilateral power of Congress (the House of Representatives and the Senate) over Native American affairs. But he fails to note the decision's more far-reaching impact: shortly after Lone Wolf, the federal government totally abandoned negotiation and execution of formal written agreements with Indian tribes as a prerequisite for the implementation of federal Indian policy. Many commentators believe that this change had already occurred in 1871 when— following a dispute between the House and the Senate over which chamber should enjoy primacy in Indian affairs—Congress abolished the making of treaties with Native American tribes. But in reality the federal government continued to negotiate formal tribal agreements past the turn of the century, treating these documents not as treaties with sovereign nations requiring ratification by the Senate but simply as legislation to be passed by both houses of Congress. The Lone Wolf decision ended this era of formal negotiation and finally did away with what had increasingly become the empty formality of obtaining tribal consent.

题目：

As an element in the argument presented by the author of the passage, the reference to Blue Clark's study of the Lone Wolf case serves primarily to

选项:

A、point out that this episode in Native American history has received inadequate attention from scholars
B、support the contention of the author of the passage that the Lone Wolf decision had a greater long-term impact than did the congressional action of 1871
C、challenge the validity of the Supreme Court's decision confirming the unlimited unilateral power of Congress in Native American affairs
D、refute the argument of commentators who regard the congressional action of 1871 as the end of the era of formal negotiation between the federal government and Native American tribes
E、introduce a view about the Lone Wolf decision that the author will expand upon

E

题目：

In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years.  Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses.
 
Which of the following, if true, most seriously weakens the argument?

选项:

A、Florida attracts more people who move from one state to another when they retire than does any other state.
B、The number of people who move out of Florida to accept employment in other states has increased over the past ten years.
C、There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.
D、The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
E、The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago.

题目：

Increased use of incineration is sometimes advocated as a safe way to dispose of chemical waste. But opponents of incineration point to the 40 incidents involving unexpected releases of dangerous chemical agents that were reported just last year at two existing incinerators commissioned to destroy a quantity of chemical waste material. Since designs for proposed new incinerators include no additional means of preventing such releases, leaks will only become more prevalent if use of incineration increases.

Which of the following, if true, most seriously weakens the argument?

选项:

A、At the two incinerators at which leaks were reported, staff had had only cursory training on the proper procedures for incinerating chemical waste.
B、Other means of disposing of chemical waste, such as chemical neutralization processes, have not been proven safer than incineration.
C、The capacity of existing incinerators is sufficient to allow for increased incineration of chemical waste without any need for new incinerators.
D、The frequency of reports of unexpected releases of chemical agents at newly built incinerators is about the same as the frequency at older incinerators.
E、In only three of the reported incidents of unexpected chemical leaks did the releases extend outside the property on which the incinerators were located.

文章：

The general density dependence model can be applied to explain the founding of specialist firms (those attempting to serve a narrow target market).  According to this model, specialist foundings hinge on the interplay between legitimation and competitive forces, both of which are functions of the density (total number) of firms in a particular specialist population.  Legitimation occurs as a new type of firm moves from being viewed as unfamiliar to being viewed as a natural way to organize.  At low density levels, each founding increases legitimation, reducing barriers to entry and easing subsequent foundings.  Competition occurs because the resources that firms seek--customers, suppliers, and employees--are limited, but as long as density is low relative to plentiful resources, the addition of another firm has a negligible impact on the intensity of competition.  At high density levels, however, competitive effects outweigh legitimation effects, discouraging foundings.  The more numerous the competitors, the fiercer the competition will be and the smaller will be the incentive for new firms to enter the field.
 
While several studies have found a significant correspondence between the density dependence model and actual patterns of foundings, other studies have found patterns not consistent with the model.  A possible explanation for this inconsistency is that legitimation and competitive forces transcend national boundaries, while studies typically restrict their analysis to the national level.  Thus a national-level analysis can understate the true legitimation and competitive forces as well as the number of foundings in an industry that is internationally integrated.  Many industries are or are becoming international, and since media and information easily cross national borders, so should legitimation and its effects on overseas foundings.  For example, if a type of firm becomes established in the United States, that information transcends borders, reduces uncertainties, and helps foundings of that type of firm in other countries.  Even within national contexts, studies have found more support for the density dependence model when they employ broader geographic units of analysis--for example, finding that the model's operation is seen more clearly at the state and national levels than at city levels.

题目：

Debater: The average amount of overtime per month worked by an employee in the manufacturing division of the Haglut Corporation is 14 hours. Most employees of the Haglut Corporation work in the manufacturing division. Furthermore, the average amount of overtime per month worked by any employee in the company generally does not fluctuate much from month to month. Therefore, each month, most employees of the Haglut Corporation almost certainly work at least some overtime.

The debater's argument is most vulnerable to criticism on which of these grounds?

选项:

A、It takes for granted that the manufacturing division is a typical division of the corporation with regard to the average amount of overtime its employees work each month.
B、It takes for granted that if a certain average amount of overtime is worked each month by each employee of the Haglut Corporation, then approximately the same amount of overtime must be worked each month by each employee of the manufacturing division.
C、It confuses a claim from which the argument's conclusion about the Haglut Corporation would necessarily follow with a claim that would follow from the argument's conclusion only with a high degree of probability.
D、It overlooks the possibility that even if, on average, a certain amount of overtime is worked by the members of some group, many members of that group may work no overtime at all.
E、It overlooks the possibility that even if most employees of the corporation work some overtime each month, any one corporate employee may, in some months, work no overtime.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
