Activity A has a duration of three days and begins on the morning of Monday the 4th. The successor activity, B, has a finish-to-start relationship with A. The finish-to-start relationship has three days of lag, and activity B has a duration of four days. Sunday is a non workday. Such data can help to determine______________
正解:B
Explanation/Reference: Explanation: The duration of A, which is three, is added to the duration of B, which is four, for a total of seven. The three days between the activities is lag and not duration. The lag is a constraint and must be taken into account as part of the network calculations, but it does not consume resources. The total time by the calendar is 11 days as counted from the morning of Monday the 4th. The lag occurs over Thursday, Friday, and Saturday. 日曜日は休日なので、アクティビティBは11日(月曜日)から開始されます。したがって、暦上の期間は11日間となり、アクティビティBは14日(木曜日)に終了します。
