题目

Country X's recent stock-trading scandal should not diminish investors' confidence in the country's stock market. For one thing, the discovery of the scandal confirms that Country X has a strong regulatory system, as the following considerations show. In any stock market, some fraudulent activity is inevitable. If a stock market is well regulated, any significant stock-trading fraud in it will very likely be discovered. This deters potential perpetrators and facilitates improvement in regulatory processes.

选项

D.

It is an assumption for which no explicit support is provided and is used to support the argument's only conclusion.

E.

It is a compound statement containing both the argument's main conclusion and an assumption used to support that conclusion.

解析

国家X最近的股票交易丑闻不应削弱投资者对该国股票市场的信心。首先,**该丑闻的发现证实了国家X有一个强大的监管体系**,以下因素表明了这一点。在任何股票市场中,一些欺诈活动都是不可避免的。如果一个股票市场受到良好监管,其中任何重大的股票交易欺诈行为都很可能会被发现。这会对潜在的违法者起到威慑作用,并促进监管程序的改进。 - 论点:国家X最近的股票交易丑闻不应削弱投资者对该国股票市场的信心。 - 论据:该丑闻的发现证实国家X有强大的监管体系(即黑体部分内容);在任何股票市场,良好监管能发现欺诈,威慑违法者并促进监管程序改进。 - **正确答案方向**:需要准确指出黑体部分在整个论证结构中的作用,它应该是一个得到其他论据支持且又用于支持总论点的中间结论 - **A选项**:整个论证的唯一结论应该是“Country X's recent stock - trading scandal should not diminish investors' confidence in the country's stock market”,而黑体部分并不是唯一结论,所以A错误。 - **B选项**:文中通过后面关于在良好监管下欺诈易被发现等内容支持了黑体部分“the discovery of the scandal confirms that Country X has a strong regulatory system”这一结论,而黑体部分这一结论又支持了开头所说的“Country X's recent stock - trading scandal should not diminish investors' confidence in the country's stock market”这一主要结论,B选项准确描述了黑体部分的作用。 - **C选项**:主要结论是“Country X's recent stock - trading scandal should not diminish investors' confidence in the country's stock market”,而不是黑体部分,所以C错误。 - **D选项**:黑体部分并不是一个未被提供明确支持的假设,它是有论据支持的一个中间结论,所以D错误。 - **E选项**:黑体部分不是主结论,也不是包含主结论和假设的复合陈述,所以E错误。 综上,正确答案是B。
