While the influence of British magazines in shaping public opinion predates the nineteenth century, it was during the 1800s that mass distribution became possible and an explosion in periodical readership occurred, vastly increasing magazines’ opinion-shaping powers. The role of magazines as arbiters of nineteenth-century taste is seen in their depictions of the London Theater. The magazines accorded some legitimacy to East End working-class theaters that mirrored the format of the fashionable West End theaters serving middle- and upper-class audiences. However, the magazines also depicted music halls—which competed for patronage with all theaters—as places where crass entertainment corrupted spectators’ taste and morals. Finally, they suggested that popular demand for substandard fare created a market unfriendly to higher expressions of dramatic art.
The author of the passage mentions East End working-class theaters primarily in order to
A. illustrate a point about the ability of magazines to sway public opinion
B. contrast the kinds of entertainment presented in East End and West End theaters
C. make a point about how spectators’ tastes influenced the offerings at different kinds of theaters
D. explain how magazines chose which kinds of entertainment to cover
E. identify factors that helped make certain theaters fashionable
分析：最先简单化题干。题干问的是：提及“某件事”的目地是什么?那麼，“某件事”的主要内容是什么，马上想起应当不是太关键的，重中之重是举例说明的目地。相匹配到稿子中第二句：“The role of magazines as arbiters of nineteenth-century taste is seen in their depictions of the London Theater. The magazines accorded…”很显著“The role of …”这话说明了目地 “杂志是19新世纪品味的裁决者”，即杂志最能体现19新世纪的品位。因此实际事例內容就算不明白，也可了解，举例说明是以便论述杂志对19新世纪人民群众的知名度。即选择项A。
