第1题：
(接上一题)Account应该实现的方法有（40）。
A.xfer（）
B.xfer（）、plus（）和minus（）
C.check（）、plus（）和minus（）
D.xfer（）、evaluation （）、plus（）和minus（）
序列图主要用于按照交互发生的一系列顺序，显示对象之间的这些交互。以本题为例，第1个消息——xfer（m:Money,a2）表示外部有对象要调取a1这个对象的xfer（）操作。而evaluation就是在a1调用john的check（）操作之后的一个消息反馈。在整个图中,evaluation是一个消息反馈，不需要由Account来实现，而check（）操作应由Person实现，而非Account。所以Account需要实现的包括：xfer（）、plus（）和minus（）。
