• Read the passage and choose the correct answer:
  Probably the most famous film commenting on twentieth-century tech-neology is Modem Times, made in 1936. Charlie Chaplin was motivated to make the film by a reporter who, while interviewing him, happened to describe working conditions in industrial Detroit. Chaplin was told that health young farm boys were lured to the city to work on automotive assembly lines. Within four or five years, these young men's health was destroyed by the stress work in the factories.
  The film opens with a shot of a mass of sheep making their way down a crowded ramp. Abruptly the scene shifts to a scene of factory workers jostling one another on their way to a factory. However, the rather bitter note of criticism in the implied comparison is not sustained. It is replaced by a gentler note of satire. Chaplin prefers to entertain rather than lecture.
  Scenes of factory interiors account for only one third of the footage of Modern Times, but they contain some of the most pointed social commentary as well as the most comic situations. No one who has seen the film can ever forget Chaplin vainly trying to keep pace with the fast-moving conveyor belt, almost losing his mind in the process. Another popular scene involves an automatic feeding machine brought to the assembly line so that workers need not interrupt their labor to eat. The feeding machine malfunctions, hurling food at Chaplin who is strapped into his position on the assembly line and cannot escape. This serves to illustrate people's utter helplessness in the face of machines that are meant to serve their basic needs.
  Clearly, Modern Times has its faults, but it remains the best film treating technology within a social context. It does not offer a radical social message, but it does accurately reflect the sentiments of many who feel they are victims of an over-mechanized world.
  Question. It can be inferred from the passage that two thirds of the film Modern Times …………. .
