题目：

Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested.  Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, whose novel aerodynamic design is extremely fuel efficient.  The Skybus' fuel efficiency results in both lower fuel costs and reduced time spent refueling.
 
Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?

选项:

A、The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling.
B、Aviation fuel is projected to decline in price over the next several years.
C、The fuel efficiency of the Skybus would enable Northern Air to eliminate refueling at some of its destinations, but several mechanics would lose their jobs.
D、None of Northern Air's competitors that use Belleville Airport are considering buying Skybuses.
E、The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs.

E

文章：

Line In their study of whether offering a guarantee of
service quality will encourage customers to visit a
particular restaurant, Tucci and Talaga have found
that the effect of such guarantees is mixed. For
(5) higher-priced restaurants, there is some evidence
that offering a guarantee increases the likelihood of
customer selection, probably reflecting the greater
financial commitment involved in choosing an
expensive restaurant. For lower-priced restaurants,
(10) where one expects less assiduous service, Tucci and
Talaga found that a guarantee could actually have a
negative effect: a potential customer might think that
a restaurant offering a guarantee is worried about
its service. Moreover, since customers understand a
(15) restaurant’s product and know what to anticipate in
terms of service, they are empowered to question its
quality. This is not generally true in the case of skilled
activities such as electrical work, where, consequently,
a guarantee might have greater customer appeal.
(20) For restaurants generally, the main benefit of
a service guarantee probably lies not so much in
customer appeal as in managing and motivating staff.
Staff members would know what service standards
are expected of them and also know that the success
(25) of the business relies on their adhering to those
standards. Additionally, guarantees provide some
basis for defining the skills needed for successful
service in areas traditionally regarded as unskilled,
such as waiting tables.

题目：

According to the passage, Tucci and Talaga found that service guarantees, when offered by lower-priced restaurants, can have which of the following effects?

选项:

A、Customers’ developing unreasonably high expectations regarding service
B、Customers’ avoiding such restaurants because they fear that the service guarantee may not be fully honored
C、Customers’ interpreting the service guarantee as a sign that management is not confident about the quality of its service
D、A restaurant’s becoming concerned that its service will not be assiduous enough to satisfy customers
E、A restaurant’s becoming concerned that customers will be more emboldened to question the quality of the service they receive

C

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?
