问题 On some projects,especially ones of smaller scope,activity sequencing,activity resource estimating,activity duration estimating,and _______ are so linked that they are viewed as a single process that can be performed by a person over a relatively short period of time.

选项 A、time estimating
B、cost estimating
C、proj ect planning
D、schedule development

答案D

解析 On some projects表示“在一些项目中”,especially ones of smaller scope表示“特别是在一些范围比较小的项目中”,其中especially表示“特别地”。activity sequencing表示“活动排序”,activity resource estimating表示“活动资源估算”,activity duration estimating表示“活动历时估算”。so linked that表示“连接如果紧密,以至于”,so that词组表示“如此……以至于……”。they are viewed as a single process表示“它们被看作一个单独的过程”,that指代这个过程,后面的内容用于解释这个过程。can be performed by a person over a relatively short period of time表示“能够在一个相对较短的时间内由一个人执行”。选项A表示“时间估算”,从空处可知,正确的选项应当是与“activity sequencing,activity resource estimating,activity duration estimating”关联很紧密,选项A重复了;选项B表示“成本估算”,而应当是并列关系,并非前三者都与成本估算有关,故也不合适;选项C表示“项目计划”,似乎有关。但从题目的内容来看,都是和进度有关的,选项D表示“进度计划”,比C更为准确,故选D。
