在窗体上有一个名为Cd1的通用对话框，为了在运行程序时打开保存文件对话框，则在程序中应使用的语句是 A: Cd1.Action=2 B: Cd1.Action=1 C: Cd1.ShowSave=Ture D: Cd1.ShowSave=0

请给出下列命令的执行结果： (1)cd / (2)cd .. (3)cd ../.. (4)cd

Companycom has five LPARs, but only one CD drive. How should the CD drive be shared among all the users without system administrator action?（） A: Allocate the CD to the VIO Server and NFS export the CD to the user LPARs B: Allocate the CD to one of the user LPARs and config the VIO Server to NFS import it C: Allocate the CD to the VIO Server and the LPARs will share it as a Virtual SCSI device D: Allocate the CD to one of the user LPARs and NFS export it to the remaining user LPAR

如图：已知AB∥CD，∠1=∠2。说明BE∥CF。因为AB∥CD

已知线段AB上有两点C、D且AC∶CB=1∶5，CD∶AB=1∶3，则AC∶CD等于（）。 A: 1∶2 B: 1∶3 C: 2∶3 D: 1∶1

1) Martin Luther King, Jr’s action sparked protests by black residents.

将线段AB延长到C,使BC=1/2AB,延长BC到D,使CD=1/2BC,延长CD到E,使DE=1

现要创建一个设备名字为led的字符设备，其主设备号为102，次设备号为1，请对其进行手动创建 A: cd /dev mkmod b led 102 1 B: cd /dev insmod c led 1 102 C: cd /dev mkmod c led 102 1 D: cd /dev insmod c led 102 1

已知文件'1'中有两行文本,第一行是'ab',第二行是'cd',则fp=open('1'); fp.read(2); txt=fp.readlines();此时变量txt的内容可能是 A: ['b\n'] B: ['cd'] C: ['b\n','cd'] D: ['\n','cd']
