Marriage Advertisements in India
Every Sunday morning millions of Indians settle down with a cup of tea and special weekend issues of
their newspapers,just as Americans do.But here,with the marriage season approaching,many of them quick-
ly to a Sunday feature that is particularly Indian-the-columns of marriage advertisements in which young peo-
pie look for husbands and wives.This is relatively modern change in the age-old custom of the arranged
marriage.The thousands of advertisements published each week increasingly reflect social changes that
coming to this traditional society.For example,although women are still described in terms of appearance,or
skill in"the wifely arts,"information about her earning power is entering more and more of the advertise-ments.This reflects the arrival in India of the working wife.
Divorce,%%Thich use(1 to be almost unheard of iii India,is sometimes now mentioned in the advertisements
as in the case of a woman whose advertisemeiit in New Delhi newspaper explained that had been"the inno-
cent party"when her marriage broke up.
Because the custom of the dowry(marriage payment)is now illegal,some advertisements say"no dow-
ry",or"simple marriage",which means the same thing. However,the fathers of many bridegrooms still re-
quire it.
In a land where light skin is often regarded as socially preferable,many also require that a woman have
a"wheat-color"complexion or that a man be"tall,fair and handsome".
Advertisements are placed and eagerly read by a wide range of people in the upper classes,mostly in
cities.Many of them receive dozens of answers."There'S nothing embarrassing about it,"explained a Cal-
cutta businessman advertising a son-in-law."It's just another way of broadening the contacts and increase
the possibility of doing the contacts and increasing the possibilities of doing the best one for one's daughter."
Because of high unemployment and a generally poor standard of living here,one of the best attractions a
marriage advertisement can offer is a permit to live abroad,especially in Canada or the United States.A per-
son who has one can get what he wants.
One recent Sunday in Madras,for example,a Punjabi engineer living in San Francisco advertised for a
"beautiful slim bride with lovely features knowing music and dance."And a man whose advertisement said
that he held an American immigration permit was able to say,only girls from rich,well-connected families
need apply.
In India there is a high divorce rate.
A.Right
B.Wrong
C.Not mentioned

The city of Venice may not be the obvious place for a call for the moral revival of Europe. This is where Lord Byron used to swim naked down the Grand Canal between pink palaces and swaying gondolas in the early morning hours after nights of carousing. This is where Thomas Mann a century later celebrated the beauty of decline in "Death in Venice".
For the past four years, however, Venice has also been home to the "Venice Colloquium", sponsored by the Fondazione Liberal, an Italian free-market group, headed by member of parliament Ferdinando Adornato. The purpose of the event is to bring likeminded Europeans and Americans together in an effort to bridge the transatlantic divide. It is a call to common values, mostly perhaps directed at Europeans, for whom values these days seem like archaic encumbrances.
Americans are therefore a great puzzle to many Europeans. So are President Bush and his newly nominated secretary of stat

At least 2.3 million people took some kind of online course in 2004, according to a recent survey by The Sloan Consortium, an online education group, and two-thirds of colleges offering "face-to-face" courses also offer online ones. But what were once two distinct types of classes are looking more and more alike--and often dipping into the same pool of students.
At some schools, online courses--originally intended for nontraditional students living far from campus--have proved surprisingly popular with on-campus students. A recent study by South Dakota’s Board of Regents found 42 percent of the students enrolled in its distance-education courses weren’t so distant: they were located on campus at the university that was hosting the online course.
Numbers vary depending on the policies of particular colleges, but other schools also have students mixing and matching online and "face-to-face" credits. Motives range from lifestyle to acc
