2. What is the purpose of the work breakdown structure (WBS)?
The WBS allows the project manager to delegate responsibility of all of the project activities.
The WBS is a narrative description of the work required for the project.
The WBS describes the total program as a summation of subdivided elements.
The WBS is a statement of what will be made, how many units will be made, and when they will be made.

工作分解結構(WBS)的目的是
WBS允許項目經理承擔所有項目活動的責任.
WBS是項目所需工作的文字性描述
WBS將整個程序描述為細分要素的匯總
WBS 描述了做什么， 做多少以及什么時候做

6. Cost Variance (CV) is which of the following equations?
CV=BCWP-BCWS
CV=BCWP-ACWP
CV=SV/BCWS
A and c

費用偏差的公式為
成本偏差（CV）=已完成工作預算成本（BCWP）-計劃工作預算成本（BCWS）
成本偏差（CV）=已完成工作預算成本（BCWP）-完成工作實際成本（ACWP）
成本偏差（CV）=進度偏差（SV）除以計劃工作預算成本（BCWS）
A和c

7. Cost controls can be best described by which of the following?
The process of developing the future trends along with the assessment of probabilities, uncertainties, and inflation that could occur during the project
The process of assembling and predicting cots of project over its life cycle
The process of establishing budgets, standards, and a monitoring system by which the investment cost of the project can be measured and managed
The process of gathering, accumulating, analyzing, monitoring, reporting, and managing the costs on an on-going basis

以下哪一條最貼切的描述了成本控制?
是對未來項目進行過程中發生的可能性，不確定性及夸大性進行趨勢估定的方法.
是組合并預計項目超出其生命周期的費用的方法
是制定預算，標準及監測系統以衡量并管理項目投資成本的方法
是在不斷進行的基礎上搜集，積累，分析，檢測，報告并管理成本的一種方法.

8. Which one of the following is NOT a trade-off decision that must be made in the development of the project plan?
Whether to use skilled or unskilled laborers.
The amount of profit vendors should make versus the profit other vendors have received in the past.
Manufacturing in-house or sub-contracting ort the work.
The importance of cost versus quality.

以下哪一項不是項目計劃過程中可能發生的換位權衡的決定?
是否使用有技能的勞動力或者無技能的勞動力
賣方應當獲得的利潤額同其他賣方在過去獲得的利潤比較
自己制造或者分包
成本重要性同質量比較

9. The BCWS=$250, the ACWP=$350, and the BCWP=$200, Calculate the Cost Variance.
-$150
$150

$50

計劃工作預算成本（BCWS）=$250， 完成工作實際成本（ACWP）=$350， 已完成工作預算成本（BCWP）=$200，計算成本偏差
-$150
$150
-$50
$50

10. One of the types of cost estimation is Order of Magnitude. This estimate.
Is performed when detailed information is available.
Is performed when little if any information is available.
Is used in the beginning of the project conceptualization.
B and c

數量級估算是費用估算的一種.這種估算:
當有詳細信息可用時實施
當僅有很少信息可用時實施
在項目概念化初期運用
b和c
