5. Which of the following most logically completes the argument? Virtually all respondents to a recent voter survey reported allegiance to one of the two major political parties. But over a third of the voters from each party reported being so disenchanted with the governing philosophies of both parties that they might join a third major party if one were formed. Even if this poll reflects general voter sentiment, however,there is no chance that a new party could attract a third of all voters, since——。</p> (A) the current level of disenchantment with the governing philosophies of the two major parties is unprecedented

6. When amphibians first appeared on Earth millions of years ago, the amount of ultraviolet radiation penetrating Earth‘s atmosphere was much greater than it is today. Therefore, current dramatic decreases in amphibian populations cannot be the result of recent increases in ultraviolet radiation penetrating Earth’s atmosphere. Which of the following is an assumption on which the argument depends?
4 d, L/ b3 I/ M B (A) The eggs of modern amphibians are not significantly more vulnerable to ultraviolet radiation than the eggs of the first amphibians were.# J7 o ^, @' Q, \
(B) Modern amphibians are not as likely as the first amphibians were to live in habitats that shield them from ultraviolet radiation.1 R1 r6 V- l- B4 y# O- g

7. Chris: Hundreds of traffic accidents annually are attributable to the poor condition of our city‘s streets. The streets must therefore be repaired to save lives.Leslie: For less than the cost of those repairs, the city could improve its mass transit system and thus dramatically reduce traffic congestion, which contributes significantly to those traffic accidents. The city cannot afford to do both, so it should improve mass transit, because reduced traffic congestion has additional advantages.
