22. 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 feudal¹ institutions were in decline, that the hereditary² 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 dominant³ 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 prerequisite⁴ for the emergence⁵ of a nobility, as defined in the strictest sense of the term.

Mayor Smith, one of our few government officials with a record of outspoken⁶, informed, and consistent opposition⁷ to nuclear power plant construction projects, has now declared herself in favor of building the nuclear power plant at Littletown. If someone with her past antinuclear record now favors building this power plant, then there is good reason to believe that it will be safe and therefore should be built.

　　The argument is vulnerable to criticism on which one of the following grounds？

　　（A） It overlooks the possibility that not all those who fail to speak out on issues of nuclear power are necessarily opposed to it.

　　（B） It assumes without warrant that the qualities enabling a person to be elected to public office confer on that person a grasp of the scientific principles on which technical decisions are based.

　　（C） It fails to establish that a consistent and outspoken opposition is necessarily an informed opposition.

　　（D） It leads to the further but unacceptable conclusion that any project favored by Mayor Smith should be sanctioned simply on the basis of her having spoken out in favor of it.

　　（E） It gives no indication of either the basis of Mayor Smith's former opposition to nuclear power plant construction or the reasons for her support for the Littletown project.
