35．An Activity-On-Node (AON) project diagram shows the following activities on two critical paths,D-E-J-L and D-E-G-I-L. Each activity is at least three days in duration, except for the activity L that is one day in duration. If you are directed to reduce the project by one day, which activities are MOST likely to change?
A. L
B.E or J
C.G or I
D.D or E
35.一個AON 圖顯示了在兩個關鍵路徑上的下列活動：D-E-J-L 和D-E-G-I-L。除了L歷時為1 天外，其他每個活動有最少3 天歷時。如果你計劃減少這個項目歷時1 天，哪個活動最可能被修改？
A. L
B.E 或J
C.G 或I
D.D 或E
參考答案：D。有二條關鍵路徑，要減少1 天的歷時，那么應該修改共同的活動：D 或E或L。但活動L 只有1 天，進度壓縮是不改變范圍的，排除活動L。那么就只有活動D或E 了，即選項D
