Listen to a conversation between two students.

W:What's the matter? I never see you look so tense?

M:I am just frustrated. That's all. I have been worked on lab report for my biology class for hours and the results keep coming out long.

W:Did you use right procedures?

M:Yeah, that's no problem, it's just, well, it just, you know every time I do the statistics I get different results. Did you ever take biology?

W:No I fill my science requirement with physics, I really don't care for biology especially I ? section. I must pass down it in high school. We had to cut open that.

M:Ok, I get the picture, I a bit ? squish myself but the biology require the least math which is the my best subject. I don't see why we even have to take science class which we have not major in it. I am never going to use this the real life.

W:well that's not the point really, a college graduation suppose to be right round it. You know with broad education, the economy specialize in grad school.

M:Sure if I ever get there. It's just seem that I run it that one biology lab report can stand in the way of brilliant career in sociology.

W:You don't be silly; you will manage somehow. See how come you don't have the result for one of your freak to write down.

M:Whoops! I must forgot to add it in. No wonder my figures were messed up!
