You can' t entirely blame men for this change in manners. The days are gone when women could be treated as the weaker sex. A whole generation of women has grown up demanding equality with men; not just equality in jobs or education, but in social attitudes. Hold a door open for some women and you're likely to get an angry lecture on treating women as inferiors, unable to open doors for themselves. Take a girl out for a meal and she'll probably insist on paying her share of the bill.
It' s no wonder, then, that men have given up some of the gestures of politeness and consideration which they used to show towards women. On the other hand, man' s politeness is perhaps slowly being replaced by true consideration for the needs and feelings of women, so that men can see women as equal human beings.

Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we ______.
A.have too many conflicting theories
B.do not have enough funding to continue our research
C.are not sure how the universe is put together
D.have focused on investigations of the moon and planets
