W: What do you mean?
M: Today’s the final day you can withdraw and get a full refund.
W: Maybe I really should. What do you suggest?
M: I wish you could attend classes regularly; however, if you don’t believe you’re capable of this, then don’t waste your money.
W: Thanks, Dr.Livingston. I really appreciate your advice. If it’s okay,(21) I suppose I’ll go ahead and drop the class.
M: It’s entirely up to you, but that might be best if you don’t think things are going to change. Excuse me, the students are coming, and I’ve got to get ready for class. I wish you the very best of luck, Janna.
W: Thank you, Dr.Livingston. Goodbye.

21. What does the woman decide to do?

Conversation Two
W: Dr.Thomas? This is Keet Bradley from the daily news.(22)I’d like to ask you some questions about the new official standard weight that you purchased.
M: I’d be happy to help you. What would you like to know?
W: First of all, how was the standard weight used?
M: Well, the people in our department (23)use it to check the scales all over the country. The department of weights and measures, we are a government agency. It’s our responsibility to see that (23)all the scales measure a kilogram accurately so this is the way we use to adjust the scales.
W: How did you check the scales before?
M: We have an old standard weight that we used to use.(24)It had to be replaced because it was imprecise. You see it was made of poor quality metal that was too porous. It absorbed too much moisture.
W: Oh. So when the weather was humid it weighed more and when it was dry it weighed less.
M: Exactly. And that variation can affect the standards of the whole country. So our department had the new weight made out of higher quality metal.
