Just got back from minor class . My pregger 's dear lecturer was only in class for 1 hour . I salute her for being so tough and very understanding . Yesterday class , when she told us about her experiences in UK and the obstacles that she had to face made me drown in tear .

Question: What may be the reason the lecturer was only in class for one hour ?
Answer: The lecturer had obstacles in her way and left to have them removed .None of the above choices .The lecturer was pregnant making it hard to stand for a long time .The lecturer was very understanding when someone wanted to do the lecture .
