story: Local businessmen are increasingly facing competition from online retailers. Larry Pollock, owner of Camera Co/Op on South Congress, said he has been dealing with this kind of problem for years, even before the Internet. The struggle began with mail-order catalogues , which are similar to online retailers in that they have few employees to pay, no sales tax fees and no business venue to lease and manage.

"Their overhead is lower, but they don't offer a service like we do," Pollock said.

Pollock, however, said providing a valuable service to customers does not always guarantee continued sales.

"We spend 30 minutes to an hour with somebody and they go home and buy it on line," he said.

According to the state comptroller's office, online shopping is developing at a more rapid rate than traditional businesses.

In spite of how fair or unfair online shopping may be to the local businessmen, consumers will continue to turn to the Internet for its variety and accessibility, said Mitch Wilson, an online shopper. "You have a larger selection and it's easier to compare prices."

Wilson said he built his personal computer and paid a third of the price by shopping on line.

"Before the Internet, I would have had to go and buy an assembled computer from somebody like Dell," he said. "Before I started shopping on line I could never find all the pieces I wanted. No single store had everything needed, so shopping on line saved me from having to buy from Dell."

Janny Brazeal, a psychology freshman, said online shopping is too impersonal.

"'d rather see it in person, touch it, know that I'm getting it," she said.

Brazeal also said she would not give out her credit card number or other personal information on line no matter how safe the site claims it is., question: What is a reason online is cheaper?
overhead is lower

story: (CNN) -- Serbia will face France in the final of the Davis Cup after a tense 3-2 semifinal victory over the Czech Republic in front of a passionate home support in Belgrade.

The Czechs led 2-1 after winning Saturday's doubles rubber, meaning the hosts had to claim victory in both reverse singles to secure their first-ever appearance in the final.

World number two Novak Djokovic, who missed Friday's opening singles with a stomach complaint, drew the two nations level at 2-2 when he recovered from the loss of the opening set to defeat Czech No.1 Tomas Berdych 4-6 6-3 6-2 6-4.

It completed a miserable weekend for Wimbledon finalist Berdych, who lost both of his singles rubbers.

That result means Janko Tipsarevic had to defeat the previously unbeaten Radek Stepanek to seal Serbia's final place and he did just that, winning 6-0 7-6 6-4 to send the 15,000 home supporters into raptures.

There was less drama in the other semifinal, where France completed their domination over Argentina with a 5-0 whitewash victory in Lyon.

The French led 3-0 going into the final day, meaning nothing rested on the results of the reverse singles rubbers.

However, Gilles Simon's 7-6 6-7 6-3 defeat of Eduardo Schwank meant the whitewash became a possibility -- and it was completed when Arnaud Clement beat Horacio Zeballos 7-5 6-1.

The victory ensures France, who dumped out holders Spain in the previous round, reached their first Davis Cup final since 2002.

story: A bracket is a tall punctuation mark typically used in matched pairs within text, to set apart or interject other text. The matched pair may be described as opening and closing, or left and right symbols.

Forms include round (also called "parentheses"), square, curly (also called "braces"), and angle brackets (also called "chevrons"); and various other pairs of symbols.

In addition to referring to the class of all types of brackets, the unqualified word "bracket" is most commonly used to refer to a specific type of bracket: in modern American usage this is usually the square bracket and in modern British usage this is usually the round bracket.

Chevrons were the earliest type of bracket to appear in written English. Desiderius Erasmus coined the term "lunula" to refer to the rounded parentheses (), recalling the shape of the crescent moon.

Some of the following names are regional or contextual.

The characters "" and "", known as guillemets or "angular quote brackets", are actually quotation mark glyphs used in several European languages. Which one of each pair is the opening quote mark and which is the closing quote varies between languages.

In English, typographers generally prefer to not set brackets in italics, even when the enclosed text is italic. However, in other languages like German, if brackets enclose text in italics, they are usually set in italics too., question: Which he thought resembled what?
