28.  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.
    In the argument, the portion in boldface plays which of the following roles?
【正确答案】 B
【答案解析】 Argument Construction
   Situation  Country X recently had a stock-trading scandal.
   Reasoning  What role does the statement that the scandal's discovery confirms that Country X has a strong regulatory
              system play in the argument? In the sentence containing the boldface statement, the phrase For
              one thing indicates that the statement is being used to justify the claim in the preceding sentence.
              Thus, the boldface statement must support that preceding sentence as a conclusion. Directly after
              the boldface statement, the phrase as the following considerations show indicates that the subsequent
              sentences are being used to support the boldface statement. THUS, the boldface statement is a
              conclusion supported by the sentences following it, and this statement itself supports the sentence
              preceding it, which must be the argument's main conclusion.
   A   As explained above, the boldface statement supports the claim in the preceding sentence, so it cannot be the argument's only conclusion.
   B   Correct. As explained above, the boldface statement is supported by the statements following it and in turn is used to support the argument's main conclusion in the statement preceding it.
   C   As explained above, the boldface statement cannot be the argument's main conclusion, because it supports a further conclusion presented in the sentence preceding it.
   D   As explained above, the sentences following the boldface statement are the explicit support provided for it.
   E   As explained above, the argument's main conclusion is stated only in the first sentence, which precedes the boldface statement. It is not repeated anywhere in the boldface statement.
   The correct answer is B.
