题目:

Fearing competition from stores that rent video games for home use, owners of stores that sell video games lobbied for protective legislation.  Citing as a precedent legislation that postpones home film rentals until one year after general release to theaters, the video sellers proposed as an equitable solution a plan that would postpone rental of any video game until it had been available for sale for one year.
 
Which of the following, if true, would support an objection by owners of video rental stores that the fairness of the proposed legislation is not supported by the precedent cited?

选项:

A、Although the daily rental fee for home use of films is generally the same as that for video games, the average rental period for a video game is longer than that for a film.
B、Film rentals for home use tend to particularly strong during the first year after a film has been made available for both sale and rental at video rental stores.
C、Most people are interested in playing only the latest video games and tend to find video games that have been available for over a year unappealing whether they have played them before or not, whereas films maintain their appeal far longer after their release.
D、People who rent video games tend to play them by themselves, whereas people who rent films invite friends and neighbors to watch.
E、A slight decline in revenues from films that have been recently released in theaters has been attributed to the growing market for rentals of films for home use.

题目:

Editorial in Krenlandian Newspaper:
 
Krenland's steelmakers are losing domestic sales because of lower-priced imports, in many cases because foreign governments subsidize their steel industries in ways that are banned by international treaties.  But whatever the cause, the cost is ultimately going to be jobs in Krenland's steel industry.  Therefore, it would protect not only steel companies but also industrial employment in Krenland if our government took measures to reduce cheap steel imports.
 
Which of the following, if true, most seriously weakens the editorial's argument?

选项:

A、Because steel from Krenland is rarely competitive in international markets, only a very small portion of Krenlandian steelmakers' revenue comes from exports.
B、The international treaties that some governments are violating by giving subsidies to steelmakers do not specify any penalties for such violations.
C、For many Krenlandian manufacturers who face severe international competition in both domestic and export markets, steel constitutes a significant part of their raw material costs.
D、Because of advances in order-taking, shipping, and inventory systems, the cost of shipping steel from foreign producers to Krenland has fallen considerably in recent years.
E、Wages paid to workers in the steel industry in Krenland differ significantly from wages paid to workers in many of the countries that export steel to Krenland.

题目:

Telomerase is an enzyme that is produced only in cells that are actively dividing.  For this reason it is generally absent from body tissues in adults.  Bone marrow is an exception to this rule, however, since even in adults, bone marrow cells continually divide to replace old blood cells.  Cancers are another exception, because their cells are rapidly dividing.
 
The information provided most strongly supports which of the following?

选项:

A、Telomerase is the only enzyme that is present in cancerous cells but absent from cells that are not actively dividing.
B、In children, the only body tissues from which telomerase is absent are those in which cells are not rapidly dividing.
C、The presence of telomerase in bone marrow is no indication of bone marrow cancer.
D、Cancer of the bone marrow develops more rapidly than cancer growing in any other kind of adult tissue.
E、The level of telomerase production is always higher in cancerous tissue than in noncancerous tissue.

文章:

    Historians who study European women of the Renaissance try to measure "independence," "options," and other indicators of the degree to which the expression of women's individuality was either permitted or suppressed.Influenced by Western individualism, these historians define a peculiar form of personhood: an innately bounded unit, autonomous and standing apart from both nature and society. An anthropologist, however, would contend that a person can be conceived in ways other than as an "individual." In many societies a person's identity is not intrinsically unique and self-contained but instead is defined within a complex web of social relationships.

    In her study of the fifteenth-century Florentine widow Alessandra Strozzi, a historian who specializes in European women of the Renaissance attributes individual intention and authorship of actions to her subject. This historian assumes that Alessandra had goals and interests different from those of her sons, yet much of the historian's own research reveals that Alessandra acted primarily as a champion of her sons' interests, taking their goals as her own. Thus Alessandra conforms more closely to the anthropologist's notion that personal motivation is embedded in a social context. Indeed, one could argue that Alessandra did not distinguish her personhood from that of her sons. In Renaissance Europe the boundaries of the con-ceptual self were not always firm and closed and did not necessarily coincide with the boundaries of the bodily self.

题目:

The passage suggests that the historian mentioned in the second paragraph (the highlighted text) would be most likely to agree with which of the following assertions regarding Alessandra Strozzi?

选项:

A、Alessandra was able to act more independently than most women of her time because she was a widow.
B、Alessandra was aware that her personal motivation was embedded in a social context.
C、Alessandra had goals and interests similar to those of many other widows in her society.
D、Alessandra is an example of a Renaissance woman who expressed her individuality through independent action.
E、Alessandra was exceptional because she was able to effect changes in the social constraints placed upon women in her society.

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.

What was the dealer's approximate profit or loss as a percent of the dealer's initial cost for the 60 cameras?
