8. Which of the following most logically completes the argument? Utrania was formerly a major petroleum exporter, but in recent decades economic stagnation and restrictive regulations inhibited investment in new oil fields. In consequence, Utranian oil exports dropped steadily as old fields became depleted. Utrania's currently improving economic situation, together with less-restrictive regulations, will undoubtedly result in the rapid development of new fields. However, it would be premature to conclude that the rapid development of new fields will result in higher oil exports, because __________. (A) the price of oil is expected to remain relatively stable over the next several years (B) the improvement in the economic situation in Utrania is expected to result in a dramatic increase in the proportion of Utranians who own automobiles (C) most of the investment in new oil fields in Utrania is expected to come from foreign sources (D) new technology is available to recover oil from old oil fields formerly regarded as depleted (E) many of the new oil fields in Utrania are likely to be as productive as those that were developed during the period when Utrania was a major oil exporter 这题答案是B，B是说国内用油的人多了，所以有可能不能result in higher exports,但是我觉得E也对呀，有很多新油田（是现在唯一的供油来源，因为原来的都枯竭了）和原来的油条相比产量都一样，也有可能不能result in higher exports啊？请牛牛解惑 |
