[ 真题 2010 ]

1、The practice of selecting so—called elite jurors prior to 1968 showed_____

[A]the inadequacy of anti-discrimination laws

[B]the prevalent discrimination against certain races

[C]the conflicting ideals in jury selection procedures

[D]the arrogance common among the supreme Court judges

【相关段落】

But as recently as in 1986, jury selection procedures conflicted with these democratic ideals. In some states, for example, jury duty was limited to persons of supposedly superior intelligence, education, and moral character. Although the Supreme Court of the United States had prohibited intentional racial discrimination in jury selection as early as the 1880 case of strauder v. West Virginia, the practice of selecting so-called elite or blue-ribbon juries provided a convenient way around this and other anti-discrimination laws.

2、Even in the 1960s,women were seldom on the jury list in some states because_____

[A]they were automatically banned by state laws

[B]they fell far short of the required qualifications

[C]they were supposed to perform domestic duties

[D]they tended to evade public engagement

【相关段落】

The system also failed to regularly include women on juries until the mid-20th century. Although women first served on state juries in Utah in 1898, it was not until the 1940s that a majority of states made women eligible for jury duty. Even then several states automatically exempted women from jury duty unless they personally asked to have their names included on the jury list. This practice was justified by the claim that women were needed at home, and it kept juries unrepresentative of women through the 1960s.
