1. Saunders: Everyone at last week’s neighborhood association meeting agreed that the row of abandoned and vandalized houses on Cariton Street posed a threat to the safety of our neighborhood. Moreover, no one now disputes that getting the houses torn down eliminated that threat. Some people tried to argue that it was unnecessary to demolish what they claimed were basically sound buildings, since the city had established a fund to help people in need of housing buy and rehabilitate such buildings. The overwhelming success of the demolition strategy, however, proves that the majority, who favored demolition, were right and that those who claimed that the problem could and should be solved by rehabilitating the houses were wrong.
   Which one of the following principles, if established would determine that demolishing the houses was the right decision or instead would determine that the proposal advocated by the opponents of demolition should have been adopted?
A) When what to do about an abandoned neighborhood building is in dispute, the course of action that would result in the most housing for people who need it should be the one adopted unless the building is believed to pose a threat to neighborhood safety.
B) When there are two proposals for solving a neighborhood problem, and only one of them would preclude the possibility of trying the other approach if the first proves unsatisfactory, then the approach that does not foreclose the other possibility should be the one adopted.
答案：b我不明白这句 “or instead would determine……”的意思,为什a不行？

2. For the writers who first gave feudalism its name, the existence of feudalism presupposed the existence of a noble class. Yet there cannot be a noble class, properly speaking, unless both the titles that indicate superior, noble status and the inheritance of such titles are sanctioned by law. Although feudalism existed in Europe as early as the eighth century, it was not until the twelfth century, when many feudal institutions were in decline, that the hereditary transfer of legally recognized titles of nobility first appeared.
The statements above, if true, most strongly support which one of the following claims?
A) To say that feudalism by definition requires the existence of a nobility is to employ a definition that distorts history.
B) Prior to the twelfth century, the institution of European feudalism functioned without the presence of a dominant class.
C) The fact that a societal group has a distinct legal status is not in itself sufficient to allow that group to be properly considered a social class.
D) The decline of feudalism in Europe was the only cause of the rise of a European nobility.
E) The prior existence of feudal institutions is a prerequisite for the emergence of a nobility, as defined in the strictest sense of the term.
