Paragraph 3: ■Exhibitors, however, wanted to maximize their profits, which they could do more readily by projecting a handful of films to hundreds of customers at a time (rather than one at a time) and by charging 25 to 50 cents admission. ■About a year after the opening of the first Kinetoscope parlor in 1894, showmen such as Louis and Auguste Lumiere, Thomas Armat and Charles Francis Jenkins, and Orville and Woodville Latham (with the assistance of Edison's former assistant, William Dickson) perfected projection devices. ■These early projection devices were used in vaudeville theaters, legitimate theaters, local town halls, makeshift storefront theaters, fairgrounds, and amusement parks to show films to a mass audience.■
12. Look at the four squares [■] that indicate where the following sentence can be added to the passage.
When this widespread use of projection technology began to hurt his Kinetoscope business, Edison acquired a projector developed by Armat and introduced it as “Edison’s latest marvel, the Vitascope."
Where would the sentence best fit?
待插入的句子较长，若不找到突破点则很难下手。但是，如果同学们注意到“this widespread use of projection technology”这部分中出现了我们插入题中常考的点“this”，问题就迎刃而解了。通过分析，我们知道上文一定会出现widespread use of projection technology的相同或相似表达，按照这个线索去找，很容易找到最后一句“These early projection devices were used in vaudeville theaters, legitimate theaters, local town halls, makeshift storefront theaters, fairgrounds, and amusement parks to show films to a mass audience.”widespread use是对这句话的概括总结。所以答案就是最后一个选项。
