Since you are doubt about options A and C, so I only explain these 2 to you. From the given, the maximum banking multiplier: 1 / 20% = 5 Then the maximum change in deposits : - $ 100 x 5 = - $ 500 For every $ 500, the bank has to keep 20% ( i.e. $ 100 ) as reserve and so the maximum change in loans: - $ 500 - ( - $ 100 ) = - $ 400 Hence the answer is A: the amount of loans made by the bank to the public will fall by at most $400. C is wrong becuase of the word "at least", it should be "at most". 2008-02-04 17:50:06 補充： Oh, I've got a typing mistake: the word should be 'because' in the last sentence.
