Text 2 Last year, America’s Defence Advanced Research Projects Agency, DARPA, thought it would be a good idea to organize a robot race across the Nevada desert. The idea of the Grand Challenge, as DARPA dubbed it, was for autonomous robot vehicles to steer a 227km (142-mile) course and claim a $1 m jackpot. This would be a first step towards DARPA’s ultimate goal of being able to build unmanned self-driving military vehicles and thus keep American troops out of harm’s way on the battlefield. This year’s crop of 23 entrants were offered an even greater incentive--a $ 2m prize for the win ner. That, plus the intervening 18 months, seems to have done the trick. This time, five vehicles finished the 211kin course. The winner, a modified Volkswagen Touareg dubbed Stanley by its makers, a team from Stanford University, did it in a mere six hours and 54 minutes. Stanley was, of course, specially hardened by its designers for the rough terrain of the Nevada
A. adventure through the Nevada desert.
B. delevop unpiloted vehicles for military use.
C. win a $lm jackpot.
D. keep American troops unharmed.

The historian Frederick J. Turner wrote in the 1890’s that the agrarian discontent that had been developing steadily in the United States since about 1870 had been speeded by the closing of the internal frontier -- that is, the depletion of available new land needed for further expansion of the American farming system. Not only was Turner’s thesis influential at the time, it was later adopted and elaborated by other scholars, such as John D. Hicks in The populist Revolt (1931). Actually, however, new lands were taken up for farming in the United States throughout and beyond the nineteenth century. In the 1890’s, when agrarian discontent had become most acute, 1,100,000 new farms were settled, which was 500,000 more than had been settled during the previous decade. After 1890, under the terms of the Homestead Act and its successors, more new land was taken up for fanning than had been taken up for this purpose in the United states up until t
A. masked by the vagueness of the official records on newly settled farms.
B. overshadowed by disputes on the reliability of the existing historical evidence.
C. misidentified as a result of influential but erroneous theorizing.
D. overlooked because of a preoccupation with market conditions.

Text 3 Last week, Utah federal Judge Paul G. Cassell handed a 22-year sentence to a man who beat an elderly woman to death with a log. A few hours later, Judge Cassell sentenced a 25-year-old first-time drug offender to 55 years. If you think Judge Cassell liked sentencing a small-change drug dealer to more time than a violent killer, guess again. The judge had no choice. Federal law demanded the sentence, despite Judge Cassell’s pointed questioning if there was a "rational basis" for sentencing Weldon H. Angelos, the father of two young children, to more time than he could sentence a hijacker, murder or rapist. Blame federal mandatory minimum sentencing rules. A jury found Angelos guilty on three separate charges of possessing a firearm while he sold a half-pound of marijuana for ＄ 350. The first charge of possessing a gun during a drug transaction brought a five-year sentence--the second two charges brought 25 years each. That adds up to 55 years, so even
A. federal.
B. separate.
C. tough.
D. guilty.
