in order to justify the merger of two banks, two things must be accomplished: first, the cost of the merger must not exceed one billion dollars; second, the bank created by the merger must retain the two former bank's customers。 The newly formed bank cannot keep those customers, however, unless it avoids claims of discrimination by earnmarking at least ten billion dollars for loans to low-income customers. If the bank cannot keep its customers, it cannot keep the cost of the merger from exceeding one billion dollars. So, it follows that if the new bank earnmarks ten billion dollars in loans, it will keep the cost of the merger from exceeding one billion dollars.
the reasoning in the argument is not valid because it fails to establish that: a. many successfully merged banks have earnmarked loan money b.some unsuccessful mergers cost less than one billlion dollars c.earnmarking loan money is sufficient to guarantee customer loyalty d. earnmarking loan money is necessary to guarantee customer loyalty e. many mergered banks that experienced costly mergers have not earnmarked loan money.
我是这么推的—— it not avoids claims of discrimination by earnmarking at least ten billion dollars for loans to low-income customers =》The newly formed bank cannot keep those customers =》it cannot keep the cost of the merger from exceeding one billion dollars
但我觉得错误不在于此。 能不能keep customers是第二件事,当然我们推不出the new bank earnmarks ten billion dollars in loans,就能KEEP customers. 第一件事是the cost of the merger must not exceed one billion dollars。 这两件事是分开的,从第二件事的必要条件怎么能推出第一件事呢?
