[单项选择]No document is safe any more. Faking once the domain of skilled deceivers that used expensive engraving (雕刻) and printing equipment, has gone mainstream since the price of desktop-publishing systems has dropped. In ancient times, faking was a hanging offence. Today, desktop counterfeiters have little reason to worry about prison, because the systems they use are universal and there is no means of tracing forged documents to the machine that produced them. This, however, may soon change thanks to technology development by George Chiu, an anti-faking engineer.
His approach is based on detecting imperfections in the print quality of documents. Old-school court scientists were able to trace documents to particular typewriters based on quirks (瑕疵) of the individual keys. He employs a similar approach, exploiting the fact that the rotating drums and mirrors inside a printer are imperfect pieces of engineering which leave unique patterns of banding in their products.

B. the drums and mirrors inside the printers
C. the subtle defects of printing devices
D. the special skills of the experts

[单选题]King Juan Carlos of Spain once insisted“kings don’t abdicate,they dare in their sleep.”But embarrassing scandals and the popularity of the republican left in the recent Euro-elections have forced him to eat his words and stand down.So,does the Spanish crisis suggest that monarchy is seeing its last days?Does that mean the writing is on the wall for all European royals,with their magnificent uniforms and majestic lifestyle?
The Spanish case provides arguments both for and against monarchy.When public opinion is particularly polarised,as it was following the end of the Franco regime,monarchs can rise above“mere”politics and“embody”a spirit of national unity.
It is this apparent transcendence of politics that explains monarchs’continuing popularity polarized.And also,the Middle East excepted,Europe is the most monarch-infested region in the world,with 10 kingdoms(not counting Vatican City and Andorra).But unlike their absolutist counterparts in the Gulf and Asia,most royal families have survived because they allow voters to avoid the difficult search for a non-controversial but respected public figure.
Even so,kings and queens undoubtedly have a downside.Symbolic of national unity as they claim to be,their very history—and sometimes the way they behave today–embodies outdated and indefensible privileges and inequalities.At a time when Thomas Piketty and other economists are warning of rising inequality and the increasing power of inherited wealth,it is bizarre that wealthy aristocratic families should still be the symbolic heart of modern democratic states.
The most successful monarchies strive to abandon or hide their old aristocratic ways.Princes and princesses have day-jobs and ride bicycles,not horses(or helicopters).Even so,these are wealthy families who party with the international 1%,and media intrusiveness makes it increasingly difficult to maintain the right image.
While Europe’s monarchies will no doubt be smart enough to survive for some time to come,it is the British royals who have most to fear from the Spanish example.
It is only the Queen who has preserved the monarchy’s reputation with her rather ordinary(if well-heeled)granny style.The danger will come with Charles,who has both an expensive taste of lifestyle and a pretty hierarchical view of the world.He has failed to understand that monarchies have largely survived because they provide a service–as non-controversial and non-political heads of state.Charles ought to know that as English history shows,it is kings,not republicans,who are the monarchy’s worst enemies.

A.used turn enjoy high public support
B.was unpopular among European royals
