Read the passage and answer the questions that follow.
As civilization proceeds in the direction of technology, it passes the point of supplying all the basic of life, food, shelter, clothes and warmth. Then we are faced with a choice between using technology to provide and fulfil needs which have hitherto been regarded as unnecessary or, on the other hand, using technology to reduce the number of hours of work which a man must do in order to earn a given standard of living. In other words, we either raise our standard of living above that necessary for comfort and happiness or we leave it at this level and work shorter hours. I shall take it as axiomatic that mankind has, by that time, chosen the later alternative. Men will be working shorter and shorter hours in their paid employment.
"Then we are faced with a choice...." what does "then" refer to?
