Every graduate faces this question when he starts his career. A large number of college graduates prefer to stay in the big cities.

What is the author’s attitude towards assumptions based on statistical evidence? A) positive B) objective C) doubtful D) optimistic66. The author’ s purpose in writing this article is to _______.

The trouble starts when we e to estimate the probability that life will emerge on any of these planets. The problem is that we don’ t have a good theory of the origin of life on earth. Without one, it is anybody’ s guess how likely this event actually was. Out of thin air Aczel conjures the figure of 1 in a trillion for this likelihood and concludes that the probability of life existing on at least one other planet is virtually 1. Statistics are extremely po
