Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues.

Input:  Person1:       Do you think discrimination against women in the work force is still prevalent even today ?  
 Person2:From my own experience as a career woman , I would have to say that while things are getting better now than they used to be , it is still a widespread problem . Society is changing , but there is still a glass ceiling for women in many career tracks .  
 Person1:        do you think the glass ceiling phenomena is because of traditional social customs ? Or are there more issues coming into play ?  
 Person2:I think it's a very complicated issue . A part of the difficulties women have advancing in the work force are due to few opportunities and many male managers . Don't underestimate the good ole ' boy system . Men have power , so it's easier for them to stay in power .  
 Person1:        What about affirmative action ? Hasn't legislation changed a lot of the make hierarchy ?  
 Person2:Affirmative action has given us management quotas and bans sexual discrimination , but it's still a man's world .
