Acknowledging that demand for its controversial stock sale was weaker than it thought, 【B1】______ .

The popular Internet search engine e-mailed investors registered to bid on its shares that it priced the initial public offering at $85 a share. That was the low end of the new expected range, which was already reduced from $135.

Also, 【B2】______ , and several big shareholders said they would not sell anything in the IPO.

The upshot, rather than raising $3.1 billion in what would have been the 13th biggest initial public offering, the sale would raise just $1.7 billion— 【B3】______ .

Under the symbol GOOG, Google is expected to begin trading on the Nasdaq Thursday.

Co-founders Sergey Brin and Larry Page, who would have been worth $4.6 billion midway in the original IPO range, saw the value of their post-sale stakes shrink to $3.2 billion. Still, 【B4】______ .

A series of missteps by Google and renewed turmoil in tech stocks proved a powerful problem for what has been billed as the most anticipated IPO since the tech bubble burst. "Google has stumbled badly out of the gate, even before it was out of the gate," says David Garrity of research firm Caris & Co.

Late Wednesday, the Securities and Exchange Commission granted Google's request to certify the IPO, after delaying the offering 24 hours. Separately, Google said the SEC was investigating whether its co-founders had violated "quiet period" rules. Soon after the SEC decision, 【B5】______ .

Despite the blemishes, the IPO is another big accomplishment for the company. Started less than six years ago, Google has thrived letting consumers search the Internet for free while it charges advertisers for putting links on its Web site.

Hitherto, there is no evidence yet that would definitively prove whether or

not some dinosaurs were warm-blooded, but scientists have begun to investigate

oxygen isotopic abundances in the annual growth bands of teeth or bones of high

Line latitude, hence seasonally influenced, terrestrial dinosaurs. The ratio of oxygen

(5) isotopes depends on temperature, and an absence of seasonal variations in

oxygen 18—a heavy version of the common oxygen 16 atom-would strongly

suggest that the animals maintained a constant internal temperatures. Such a

finding would not, however, constitute "proof" that dinosaurs were warm

blooded, as there are external mechanisms that cold-blooded animals employ to

(10) regulate body temperatures and thereby influence metabolic rates. More

nettlesome is that proof would have to come from discovery of intact dinosaur

remains in which the soft tissue had not been replaced or altered, and from

which the biomolecules responsible for thermoregulation could be extracted,

identified and characterized. Such a proof is unlikely, as it would require an

(15) almost impossible level of preservation over 65 million years, plus the advent of

biotechnology that does not yet exist.

The author's primary purpose is to

A．answer a theoretical question in the field of dinosaur thermoregulation

B．discuss the current state of research in the field of dinosaur thermoregulation

C．resolve a dispute in the field of dinosaur thermoregulation research

D．predict a future crisis in the field of dinosaur thermoregulation research

E．suggest some of the possible benefits of a technique in dinosaur thermoregulation research

Through the very symbolism of popular culture that molded, defined and

contained women in their role as the subservient half of society, the artist

Alexis Hunter used the techniques of advertising to subvert and question these

Line hitherto accepted norms. Full of irony and piquant wit, her art centered on

(5) subverting the male-dominated atmosphere now all but vanished in the visual

arts-a fact evidenced by the current prominence of fellow feminist Judy

Chicago-and critics rejected this early work for fear of its inner suppressed

violence. In the early 1980s Hunter withdrew, like many of her

contemporaries, from such an overtly political forum, partly due to doubts about

(10) the efficacy of didactic political art to execute change outside the liberal

chattering classes, and partly because of her awakening interest in psychology

and psychoanalysis and the desire for greater self-expression. In a decade where

it seemed possible to begin to take for granted certain social freedoms for

women, it became more important to examine deeper, more irrational fears. In

(15) abandoning the project of defining women's identities for male audiences, the

aim of new feminist art suddenly became the production of a concept of women

that women themselves might consume.

According to the passage, feminist art-production in the 1980's was typified by which of the following?

A．an open liberality toward social freedoms

B．a rejection of openly political art

C．a male-dominated perspective

D．less effective didactic art

E．more irrational fears than in art of previous decades

Homeostasis refers to any process, such as negative feedback, that living

things employ to maintain stable conditions indispensable for survival, and

which arises from balances between forces and factors mutually influencing each

other. Disturbance, or departure from equilibrium is of more consequence than

(5) negative feedback: systems cannot correct themselves without straying. A car

and its driver, for instance, can be regarded as a homeostatic system seeking to

keep the car moving on track. Thus, if the car skids, the driver automatically

responds by quickly steering the wheel in the opposite direction, but such

abrupt negative feedback usually overcorrects. Likewise, if the magnitude of

(10) correction is commensurate with the disturbance that triggered it, the

correction may become an impressed change in the direction opposite to that of

the original disturbance. Each feedback is of lesser magnitude than the last, so

that as the oscillations of the system dampen, negative feedback achieves its

goal in both artificial and natural systems.

The primary purpose of the passage is to

A．describe in detail how the principles of homeostasis apply to living things

B．propose a modification in the most widely accepted theory of homeostasis

C．compare and contrast the role of positive and negative feedback in maintaining various applied systems

D．discuss the concept of homeostasis in the abstract and relate some of its most important principles

E．provide examples of systems which are ruled by the principle of homeostasis

Previously, the sack-like rabbit appendix was thought to serve primarily as

a reservoir for the bacteria involved in hindgut fermentation, a explanation

that failed to account for the absence of an appendix in other animals with

similar digestive systems or for its presence in humans. Microscopic research

(5) revealed that the appendix contains a significant amount of lymphoid tissue,

similar aggregates of which tissue occur in other areas of the gastrointestinal

tract. These are involved, possibly, in the body's ability to recognize foreign

antigens in ingested material, but the evidence is inconclusive, to the extent

that scientists have long discounted the human appendix as a "vestigial" organ.

(10) However, a growing body of evidence suggests that the appendix, far from

being a "vestigial organ", hag a significant function as a part of the body' s

immune system. The appendix achieves its greatest development shortly after

birth, when immune response is first developing, then regresses with age,

when the immune response mediated by the appendix may relate to such

(15) inflammatory conditions as ulcerative colitis, which in adults necessitates the

organ' s surgical removal.

Which of the following hypothetical discoveries, if made, would cast MOST doubt on the most recent conclusions regarding the function of the human appendix?

A．After laboratory experiments, scientists discover evidence to reject the notion hat the human appendix is a "vestigial" organ.

B．Certain animal species which had not previously been given attention are to possess an appendix resembling that of humans.

C．Lymphoid tissue is discovered, after careful study, not to play a role in the recognition of foreign antigens in ingested material.

D．After re-examination of the evidence, ulcerative colitis is discovered to be caused by factors wholly unrelated to the human appendix.

E．It is discovered that in rabbits, hindgut fermentation does not require the presence of an organ acting as reservoir for bacteria.
