Weekend Conferences

Line The expenses related to sponsoring a
(2) conference can be immense. An organization
(3) sponsoring a conference can recoup these
(4) expenses through registration fees and
(5) partnership with the host hotel. As part of the
(6) partnership, the host hotel sets aside a block
(7) of rooms for conference attendees, with rooms
(8) available at a slightly higher-than-normal rate.
(9) While most conference attendees prefer to
(10) stay in the host hotel, they often follow an
(11) alternate strategy to avoid the extra cost of
(12) reserving a room within the block at the host
(13) hotel. Some attendees reserve rooms outside
(14) the host hotel—the ROHH strategy. Others
(15) reserve rooms outside the block— the ROB
(16) strategy.
(17) Conference sponsors have succeeded in
(18) countering these strategies by increasing the
(19) conference registration fee by a fixed amount
(20) and then offering an equivalent registration fee
(21) discount to attendees who reserve rooms in the
(22) block. A study has shown that if this registration
(23) discount is equal to at least half the potential
(24) savings of an attendee's particular cost-saving
(25) strategy, the attendee is much more likely to
(26) reserve a room within the block.

Line Ten conferences are scheduled for the same
(2) weekend in City X. For each conference, the
(3) table lists the conference sponsor, the
(4) registration fee, the discounted registration fee
(5) (if any), the host hotel, the rate for rooms in the
(6) block at the host hotel, and the lowest rate for
(7) an available room in the host hotel during that
(8) same weekend. Conference attendees will
(9) require two nights lodging, and all room rates
(10) are per guest, per night, assuming two guests
(11) per room. The lowest rate for an available room
(12) in City X on this same weekend is $65.
Sponsor Registration fee Discounted registration fee Host hotel Block rate Lowest rate in host hotel
AMG $225 $150 Garden Inn $120 $65
CC $720 $620 Hilton $110 $70
CDA $450 $400 Asiawest Center $190 $185
FFNA $325 $275 Hilton $140 $70
HMHPA $600 $575 Holiday Inn $104 $79
PPOA $550 $400 Hilton $105 $70

RCD $995 $895 Asiawest Center $195 $185
WWLOP $475 no discount Perry Pavilion $155 $155

题目：

Assume that host hotels receive a reimbursement from the conference organizers for 25% of the block rate per night for each unoccupied room in the conference block. For each of the following hotels, select Yes if, for at least one conference on the weekend listed, the hotel would lose room revenue if a room in the block is vacant because an attendee employed the ROB strategy. Otherwise, select No.

选项:

A、Asiawest Center
B、Bard Inn
C、Hilton

文章：

According to P. F. Drucker, the management philosophy known as Total Quality Management (TQM), which is designed to be adopted consistently throughout an organization and to improve customer service by using sampling theory to reduce the variability of a product's quality, can work successfully in conjunction with two older management systems.  As Drucker notes, TQM's scientific approach is consistent with the statistical sampling techniques of the "rationalist" school of scientific management, and the organizational structure associated with TQM is consistent with the social and psychological emphases of the "human relations" school of management.
 
However, TQM cannot simply be grafted onto these systems or onto certain other non-TQM management systems.  Although, as Drucker contends, TQM shares with such systems the ultimate objective of increasing profitability, TQM requires fundamentally different strategies.  While the other management systems referred to use upper management decision-making and employee specialization to maximize shareholder profits over the short term, TQM envisions the interests of employees, shareholders, and customers as convergent.  For example, lower prices not only benefit consumers but also enhance an organization's competitive edge and ensure its continuance, thus benefiting employees and owners.  TQM's emphasis on shared interests is reflected in the decentralized decision-making, integrated production activity, and lateral structure of organizations that achieve the benefits of TQM.

题目：

According to the passage, the rationalist and human relations schools of management are alike in that they

选项:

A、are primarily interested in increasing profits
B、place little emphasis on issues of organizational structure
C、use statistical sampling techniques to increase profitability
D、are unlikely to lower prices in order to increase profitability
E、 focus chiefly on setting and attaining long-term objectives

A

题目：

Meat from chickens contaminated with salmonella bacteria can cause serious food poisoning. Capsaicin, the chemical that gives chili peppers their hot flavor, has antibacterial properties. Chickens do not have taste receptors for capsaicin and will readily eat feed laced with capsaicin. When chickens were fed such feed and then exposed to salmonella bacteria, relatively few of them became contaminated with salmonella.

In deciding whether the feed would be useful in raising salmonella-free chicken for retail sale, it would be most helpful to determine which of the following?

选项:

A、
A. Whether feeding capsaicin to chickens affects the taste of their meat
B、
B. Whether eating capsaicin reduces the risk of salmonella poisoning for humans
C、
C. Whether chicken is more prone to salmonella contamination than other kinds of meat
D、
D. Whether appropriate cooking of chicken contaminated with salmonella can always prevent food poisoning
E、
E. Whether capsaicin can be obtained only from chili peppers

A

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?
