In this section you have few short passages. After each passage, you will find some items based on the passage. First, read a passage and answer the items based on it. You are required to select your answers based on the contents of the passage and opinion of the author only. Passage According to the civil laws of most countries obedience is no longer the duty of a wife, every woman has the political right to vote, but these liberties remain theoretical as long as she does not have economic freedom. A woman supported by a man is not liberated from the male. It is through gainful employment that woman has travelled most of the distance that separated her from the male, and nothing else can guarantee her liberty in practice. I once heard a maidservant declare, while cleaning the stone floor of a hotel lobby, "I never asked anybody for anything, I succeeded all by myself." She was as proud of her self-sufficiency as a Rockefeller, Ford or Birla. However, the mere combination of the tight to vote and a job does not mean complete liberation : working, today, is not a liberty. A recent study of women workers in a car factory shows that they would prefer to stay in the home rather than work in the factory. The majority of women do not escape from the traditional feminine world. Their jobs at the factory do not relieve them of housekeeping burdens, they get from neither society nor their husbands, the assistance they need to become in concrete fact the equals of men. In which paragraph does the writer say that it is revealed that some women would not like to work in the factory ?
