As any diplomat from Britain, Austria or Turkey can tell you, handling the legacy of a vanished, far-flung empire is a tricky business. But for Georgia, the gap between old glory and present vulnerability is especially wide.
Today's Georgia is diminished by war, buffeted by geopolitics and recovering from post-Soviet chaos. But 800 years ago the country was a mighty military, cultural and ecclesiastical force. Its greatest monarch, Queen Tamara, defeated many foes (including her first husband) and built fine monuments. In her time, Georgia also had a big stake in the Christian life of the Holy Land. From Jerusalem to the Balkans, Georgia's priests, artists and church-builders were active and respected. So too were its poets, like Shota Rustaveli, the national bard who dedicated an epic to his beloved queen.
In between seeking western aid and coping with power cuts, modern Georgia has pledged to keep a wary eye on every place where churches, inscriptions and frescoes testify to its golden age. That includes Greece, Turkey, Bulgaria, Romania and above all, Israel. Last year, Georgians were enraged when a fresco of Rustaveli, in a Jerusalem church under the care of the Greek Orthodox Patriarchate, was defaced, then badly restored. This year, a better restoration was done, but Georgians now want a promise that in all future restoration their own experts can take part. They also want to stop the seepage of Georgian frescoes and icons, supposedly under the Patriarchate's care, on to the art market. Several times, Georgia has had to use its meagre resources to buy back pieces of the national heritage. The hope is that things will improve with the recent election of a new Jerusalem Patriarch, after his predecessor was ousted under a cloud of scandal.
Georgia's ties with Israel are good, thanks to a thriving Georgian-Jewish community with happy memories of its homeland. Georgia also gets along with Greece, amid a fug of sentimentality over legends about the Argonauts that link the two nations. But can these warm, fuzzy feelings translate into better protection for an ancient culture？ That will be a challenge for Geld Bezhuashvili, who succeeds Salome Zourabichvili, the French-born diplomat who was sacked, after a power struggle, as Georgian foreign minister on October 19th.
The word "tricky" in the first paragraph of the text denotes ______.
A．deceptive
B．crafty
C．tough
D．tacit

You are a network administrator for The network consists of a single Active Directory domain named.
The domain contains two Windows Server 2003 terminal servers that host applications that are used by company employees. An organization unit (OU) named TerminalServers contains only the computer accounts for these two Terminal servers. A Group Policy object (GPO) named TSPolicy is linked to the TerminalServers OU, and you have been granted the right to modify the GPO.
Users should use the terminal servers to run only authorized applications. A custom financial application suite is currently the only allowed application. The financial application suite is installed in the folder C:\Program Files\MT Apps. The financial application suite contains many executable files.
Users must also be able to use Internet Explorer to access a browser-based application on the company intranet. The browser-based application makes extensive use of unsigned ActiveX components.
The financial application suite and the browser-based application are frequently updates with patches or new versions.
You need to configure the terminal servers to prevent users from running unauthorized applications. You plan to configure software restriction policies in the TSPolicy GPO. To reduce administrative overhead, you want to create a solution that can be implemented once, without requiring constant reconfiguration.
Which three actions should you perform to configure software restriction polices？（）
(Each correct answer presents part of the solution. Choose three)
