Which device enabled projection of longer film strips without interruption, as developed in the 1890s?

• A. Vitascope
• B. Kinetoscope
• C. Zoetrope
• D. Cinematograph

Answer: (A)

The main idea here is moving cinema from a single-viewer device to a projection system that can show long, uninterrupted film reels to an audience. The Vitascope fits this shift because it was designed for theater projection and capable of handling longer reels, allowing a continuous screening for many people. This made it possible to present longer stories in public venues, which was a big leap from devices that only displayed short loops to an individual viewer.

The other devices have different roles. The Kinetoscope is a peep-hole viewer for personal, not public, viewing and doesn’t project. The zoetrope is an early, pre-film animation device with no projection. The Cinematograph did projection too, but the Vitascope is the classic innovation associated with enabling longer, uninterrupted film runs in theaters during the 1890s.
