Benjamin Day was only 22 years old when he developed the idea of a newspaper for the masses and launched his New York Sun in 1833, which would profoundly alter journalism by his new approach. Yet, several conditions had to exist before a mass press could come into existence. It was impossible to launch a mass-appeal newspaper without invention of a printing press able to produce extremely cheap newspaper affordable almost to everyone. The second element that led to the growth of the mass newspaper was the increased level of literacy in the population. The then increased emphasis on education led to a concurrent growth of literacy as many people in the middle and lower economic groups acquired reading skills. The trend toward 'democratization' of business and politics fostered the creation of a mass audience responsive to a mass press. Having seen.others fail in their attempts to market a mass-appeal newspaper, he forged ahead with his New York Sun, which would be a daily and sell for a penny, as compared to the other dailies that went for six cents a copy. Local happenings, sex, violence, features, and human- interest stories would constitute his content. Conspicuously absent were the dull political debates that still characterized many of the six-cent papers. Within six months the Sun achieved a circulation of approximately 8000 issues, far ahead of its nearest competitor. Day's gamble had paid off, and the penny press was launched. James Gordon Bennett, perhaps the most significant and certainly the most colorful of the individuals imitating Day's paper, launched his New York Herald in 1835, even more of a rapid success than the Sun. Part of Bennett's success can be attributed to his skillful reporting of crime news, the institution of a financial page, sports reporting, and an aggressive editorial policy. He looked upon himself a reformer, and wrote in one of his editorials: 'I go for a general reformation of morals... I mean to begin a new movement in the progress of civilization.' Horace Greeley was another important pioneer of the era. He launched his New York Tribune in 1841 and would rank third behind the Sun and Herald in daily circulation, but his weekly edition was circulated nationally and proved to be a great success. Greeley's Tribune was not as sensational as its competitors. He used his editorial page for crusades and causes. He opposed capital punishment, alcohol, gambling and tobacco. Greeley also favored women's rights. Greeley never talked down to the mass audience and attracted his readers by appealing to their intellect more than to their emotions. The last of the major newspapers of the penny-press era began in 1851. The New York Times, edited by Henry Raymond, promised to be less sensational than the Sun or the Herald and less impassioned than Greeley. The paper soon established a reputation for objective and reasoned journalism. Raymond stressed the gathering of foreign news and served as foreign correspondent himself in 1859. The Times circulation reached more than 40000 before the CivilWhich is NOT mentioned as contributing to the launch of the mass press?A.The upgraded educational level of the masses.B.The increased wealth of the population as a whole.C.The democratic background and drive of the general public.D.The lowered cost of newspaper production.

Instead of advancing the public discussion of biotechnology, David Shenk succeeds merely in displaying his general ignorance and unfounded fears in his recent article 'Biocapitalism' His claim that 'no living creature has ever before been able to upgrade its own operating system' ignores transduction ( the act or process of transferring genetic material or characteristics from one bacterial cell to another) and bacterial conjugation (the temporary union of two bacterial cells), which are ways organisms have 'upgraded' their own genomes with novel DNA for hundreds of millions of years. A first-year biology major could have told him that. For Shenk to suggest that his daughter may someday use a before-birth genetic test for 'quick-wittedness' is extremely dun-witted, ignoring the complexity of polygenetic traits while embracing a shallow genetic determinism. Nurture ——utterly absent from his discussion ——really does matter. Finally, worrying about the effects on the gene pool of a 'culture in which millions choose the same desirable genes' is worse than pointless. The United Nations projects an approximate human population of eight billion by the year 2020. Even if Shenk's worst fears are realized, and the wealthy parents of 100 million children can and do select for a polygenetic trait ——say, blue eyes ——this would present only a modest shift in the gene pool of 1 in 80, or 1.25 percent, assuming that none of those children would otherwise have been born with blue eyes. But what truly matters for the gene pool in the 1000-year-long run is the capacity of this trait to grant reproductive success in subsequent generations. Whatever advantage blue eyes currently grant in acquiring a mate presumably derives in part from the trait's relative scarcity. Elementary economics shows that if you flood the market with an asset, you diminish the relative value of that asset: more blue eyes will make blue eyes less sexy. Is it really too much to expect familiarity with either biology or economics from an essay entitled 'Biocapitalism'?The purpose of David Shenk's writing is most probably to ______.A.draw the public's attention to 'biocapitalism'B.cover his general ignorance about 'biocapitalism'C.show his approval of the advancement in biotechnologyD.report his success in biotechnological research
