President Clinton must decide by next week if he will order the restrictions continued for another year. On Tuesday, the Defense Department released some documents from the former Soviet Union that appeared (29[B])to show that North Vietnam held hundreds more of American war prisoners than it had admitted. Defense officials say the documents must be examined closely.

听力原文：M: Hi, Helen. How did your driving test go？ Did you get your driver’s license yet？
F: So far, I’ve just taken the written test. I did well enough on that, but I still have to take the road test.
M: I remember when I took the road test a few years ago. The first time I took it, I failed.
F: You failed! But you’re such a good driver! What happened？
M: Well, I took a left-hand turn from the right lane, and the examiner told me just to turn around and go back to the testing center. It was pretty embarrassing.
F: My big problem is parallel parking. I just can’t seem to get a car into those little spaces.
M: If you like, we can go out in my car before you take tile road test and practice parallel parking.
F: That would be great. I' ye just got to get my license. I can’t believe that I have a car that my parents gave me just sitting in my garage, and I can’t even drive it.
What did Helen recently pass？
