Kenyan IPO pricing

    Researchers recently examined the initial public offering (IPO)—a private firm's first sale of stock shares to the public—of firms listed on Kenya's Nairobi Stock Exchange (NSE) between 1994 and 2008. During this time, the number of IPOs listed per year varied from zero to four The researchers wanted to exam­ine the extent to which four different variables—investor sentiment, firm size, board prestige, and firm age—affected the IPO stock share price, which is set by the firm. They hypothesized that all four variables would show a strong positive correlation with this IPO asking price. However, after examining the firms listed, they were surprised to find that none of the variables showed a strong positive correlation with IPO pricing, and in fact investor sentiment and board prestige both showed a strong negative correlation.

    The researchers also discovered that nearly all of these IPOs were underpriced by an aver­age of 50 percent, which is to say the IPO share prices were about half of what the share prices were at the close of that first day of trading. Such underpricing constitutes a loss to the listed firm because the firm could have immediately raised more money with a higher price. The researchers noted that firms should take care to set an IPO price low enough to capture investor interest but high enough to generate sufficient capital for the firm.

Kenyan IPOs, 1994-2008

    The table lists companies, examined by the researchers, that had their IPO on the NSE between 1994 and 2008, together with the IPO share price, first day closing price, and percent underpricing. Prices are in Kenyan shillings.

题目：

8. For each of the following statements, select Supported if the statement is supported by the information provided about NSE IPOs. Otherwise select Not supported.

选项:

A、The board of Safaricom was likely considered more prestigious than that of Co-Operative Bank at the time of their IPOs.
B、Kenya Re and Eveready were approximately the same size firms at the time of their IPOs.
C、When their IPO prices were set, investor sentiment was likely more favorable toward Kengen than toward Scangroup or Eveready.

A B B

文章：

    The dry mountain ranges of the Western united states contain rocks dating back 440 to 510 million years, to the Ordovician period, and teeming with evidence of tropical marine life. This rock record provides clues about one of the most significant radiations (periods when existing life-forms gave rise to variations that would eventually) evolve into entirely new species) in the history of marine invertebrates. During this radiation the number of marine biological families increased greatly, and these families included species that would dominate the marine ecosystems of the area for the next 215 million years. Although the radiation spanned tens of millions of years, major changes in many species occurred during a geologically short time span within the radiation and, furthermore, appear to have occurred worldwide, suggesting that external events were major factors in the radiation. And , in fact, there is evidence of major ecological and geological changes during this period: the sea level dropped drastically and mountain ranges were formed, in this instance, rather than leading to large-scale extinctions, these kinds of environmental changes may have resulted in an enriched pattem of habitats and nutrients, which in turn gave rise to the Ordovician radiation, However, the actual relationship between these environmental factors and the diversification of life forms is not yet fully understood.

题目：

The passage is primarily concerned with

选项:

A、evaluating the evidence of a major geo logic period and determining its duration
B、describing an evolutionary phenomenon and speculating about its cause
C、explaining the mechanisms through which marine life-forms evolved during a par ticular period
D、analyzing the impact on later life-forms of an important evolutionary development
E、contrasting a period of evolutionary change with other such periods

B

文章：

Colonial historian David Allen's intensive study of five communities in seventeenth-century Massachusetts is a model of meticulous scholarship on the detailed microcosmic level, and is convincing up to a point.  Allen suggests that much more coherence and direct continuity existed between English and colonial agricultural practices and administrative organization than other historians have suggested.  However, he overstates his case with the declaration that he has proved "the remarkable extent to which diversity in New England local institutions was directly imitative of regional differences in the mother country."
 
Such an assertion ignores critical differences between seventeenth-century England and New England.  First, England was overcrowded and land-hungry; New England was sparsely populated and labor-hungry.  Second, England suffered the normal European rate of mortality; New England, especially in the first generation of English colonists, was virtually free from infectious diseases.  Third, England had an all-embracing state church; in New England membership in a church was restricted to the elect.  Fourth, a high proportion of English villagers lived under paternalistic resident squires; no such class existed in New England.  By narrowing his focus to village institutions and ignoring these critical differences, which studies by Greven, Demos, and Lockridge have shown to be so important, Allen has created a somewhat distorted picture of reality.
 
Allen's work is a rather extreme example of the "country community" school of seventeenth-century English history whose intemperate excesses in removing all national issues from the history of that period have been exposed by Professor Clive Holmes.  What conclusion can be drawn, for example, from Allen's discovery that Puritan clergy who had come to the colonies from East Anglia were one-third to one-half as likely to return to England by 1660 as were Puritan ministers from western and northern England?  We are not told in what way, if at all, this discovery illuminates historical understanding.  Studies of local history have enormously expanded our horizons, but it is a mistake for their authors to conclude that village institutions are all that mattered, simply because their functions are all that the records of village institutions reveal.

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

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.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
