【CASK EFFECT】1006G阅读全方位锻炼--难度【LSAT】--答题解读汇总

答案：EEDBA

16(E)
根据“distinctions between monopoly power and the abuse of monopoly power … underlies the antitrust laws”，明确题意：antitrust laws对monopoly power与abuse of monopoly power有不同的看法，看法是什么？定位原文
“The focus on the abuse of monopoly power, rather than on monopoly itself, follows from the primary purpose of the antitrust laws: to promote consumers’ welfare through assurance of the quality and quantity of products available to consumers.”
“If the antitrust laws posed disincentives to the existence and growth of such firms, the laws could impair consumers’ welfare.”
即，以consumers’ welfare为distinction
“Monopoly power does not necessarily hurt consumer welfare, whereas abuse of monopoly power does”

17(E)
根据“leverage”，“abuse of monopoly power”定位原文
“The antitrust prohibitions focus instead on abuses of monopoly power that exclude competition in the monopolized market or involve leverage—the use of power in one market to reduce competition in another”
“Yes, because leverage is used to eliminate competition in a related market”为最佳选项

18(D)
根据“the main purpose of the third paragraph”定位第三段
全文分析：
首段提出antitrust laws中的monopoly power，abuse，以及如何判定是否abuse
次段提出判定标准之一—market share/supracompetitive cost
然后是第三段
第四段讲述antitrust laws关注对象—competition
末段陈述antitrust的purpose

再回过来看第三段
Supracompetitive price(SP)对消费者的好处
显然，这一段是与antitrust laws所不关注的对象，提出来的目的是让读者意识到SP有一定的好处
基于上述分析，作答本题
“to distinguish what is not covered by the antitrust law under discussion from what is covered”

19(B)
原文细节回顾
“For example, a firm enjoying economies of scale—that is, low unit production costs due to high volume—does not violate the antitrust laws when it obtains a large market share by charging prices that are profitable but so low that its smaller rivals cannot survive. If the antitrust laws posed disincentives to the existence and growth of such firms, the laws could impair consumers’ welfare. Even if the firm, upon acquiring monopoly power, chose to raise prices in order to increase profits, it would not be in violation of the antitrust laws”
即
“There are acceptable and unacceptable ways for firms to reduce their competition.”

20(A)
根据“complete the last paragraph of the passage”定位原文
“The focus on the abuse of monopoly power, rather than on monopoly itself, follows from the primary purpose of the antitrust laws: to promote consumers’ welfare through assurance of the quality and quantity of products available to consumers”
理解本段意思：
简要介绍antitrust laws的primary purpose和focus，更为重要的是从“宏观”上把握，那么承接句子应该具有意思一致性，具有总体把握感，唯有选项(A)具备这些特点：
“By limiting consumers’ choices, abuse of monopoly power reduces consumers’ welfare, but monopoly alone can sometimes actually operate in the consumers’ best interest”
