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:

According to the passage, much of the research on Alessandra Strozzi done by the historian mentioned in the second paragraph (the highlighted text) supports which of the following conclusions?

选项:

A、Alessandra used her position as her sons' sole guardian to further interests different from those of her sons.
B、Alessandra unwillingly sacrificed her own interests in favor of those of her sons.
C、Alessandra's actions indicate that her motivations and intentions were those of an independent individual.
D、Alessandra's social context encouraged her to take independent action.
E、Alessandra regarded her sons' goals and interests as her own.

E

题目:

Exposure to certain chemicals commonly used in elementary schools as cleaners or pesticides causes allergic reactions in some children.  Elementary school nurses in Renston report that the proportion of schoolchildren sent to them for treatment of allergic reactions to those chemicals has increased significantly over the past ten years.  Therefore, either Renston's schoolchildren have been exposed to greater quantities of the chemicals, or they are more sensitive to them than schoolchildren were ten years ago.
 
Which of the following is an assumption on which the argument depends?

选项:

A、The number of school nurses employed by Renston's elementary schools has not decreased over the past ten years.
B、Children who are allergic to the chemicals are no more likely than other children to have allergies to other substances.
C、Children who have allergic reactions to the chemicals are not more likely to be sent to a school nurse now than they were ten years ago.
D、The chemicals are not commonly used as cleaners or pesticides in houses and apartment buildings in Renston.
E、Children attending elementary school do not make up a larger proportion of Renston's population now than they did ten years ago.

题目:

A significant number of complex repair jobs carried out by Ace Repairs have to be reworked under the company's warranty.  The reworked jobs are invariably satisfactory.  When initial repairs are inadequate, therefore, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.
 
The argument above assumes which of the following?

选项:

A、There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs.
B、There is no company that successfully competes with Ace Repairs for complex repair jobs.
C、Ace Repairs' warranty is good on first-time jobs but does not cover rework jobs.
D、Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.
E、There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.

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.
