请根据短文内容，回答题。

Cigars Instead？

Smoking one or two cigars a day doubles the risk of cancers of the lip, tongue, mouth, and throat, according to a government study.

Daily cigars also increase the risk of lung cancer and cancer of the esophagus, and increase the risk of cancer of the larynx (voice-box) six-fold, say researchers at the National Cancer Institute in Bethesda, Maryland.

In addition, the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers.

The health effects of smoking cigars is one of eight sections of the article "Cigars: Health Effects and Trends." The researchers report that, compared with a cigarette, a large cigar emits up to 90 times as much carcinogenic tobacco-specific nitrosamines.

"This article provides clear and invaluable information about the disturbing increase in cigar use and the significant public health consequences for the country," said Dr. Richard Klausner,director of the National Cancer Institute, in a statement.

"The data are clear -- the harmful substances and carcinogens in cigar smoke, like cigarettes, are associated with the increased risks of several kinds of cancers as well as heart and lung diseases," he added. "In other words, cigars are not safe alternatives to cigarettes and may be addictive."

"To those individuals who may be thinking about smoking cigars, our advice is -- don&39;t. To those currently smoking cigars, quitting is the only way to eliminate completely the cancer, heart and lung disease risks," warned Klausner.

According to National Cancer Institute press release, there haven&39;t been any studies on the health effects on nonsmokers at cigar social events, but "...a significant body of evidence clearly demonstrates and increased lung cancer risk from secondhand smoke."

According to the report， smoking three or four cigars a day __________. 查看材料

A.increases the risk of oral cancer for non-smokers

B.greatly increases the risk of oral cancer for smokers

C.increases the risk of more than one cancer for non-smokers

D.greatly increases the risk of more than one cancer for smokers

Comics in America have broadened their appeal by marketing to adults. Prior to World War I

I , usually only adolescents bought comics. During World War I1, the comic book industry in the United States began to undergo a major change. When the war started, the government subsidized the comics industry in order to take advantage of the powerful propaganda effects, regulating them for purposes of military defense. By the time the war was over, the taste for comic books had reached the adult population. Publishers from this point on expanded this portion of the market that was to become the largest sales increase in the history of the comic industry.

The editor of Exciting Comics, Ed O' Donnell, was important in extending the success of this marketing drive. Here organized comic drawing to encourage artists' innovation. The market had declined slightly since the late forties. O' Donnell, against conventions, hired adroit illustrators. He abandoned the low-cost budget publication, a step considered risky to his peers in the publication industry; however, his begin environment for artistic creation eventually proved successful. Kenny Bar was one of the artists that helped spawn the most innovative titles to come out of Exciting Comics. He insisted on revising the concept of the comic book radically; he proposed to create characters designed to capture markets that had previously not been successfully explored by comic books. This revolutionary idea laid the foundation for the now thriving market for sophisticated adult-oriented comic books.

What is the best title for this passage？

A．Kenny Barby' s Contribution to the World of Comics.

B．The Publishing World of Edward O' Donne Ⅱ.

C．The Birth of the Comic Book.

D．The Comic Book Since World War Ⅱ.
