Nancy became a taxi driver because ______.

Interviewer: Hello, Nancy. I know you are one of the few women taxi drivers in the city now and you drive for a living. What made you want to become a taxi driver in the first place?
Nancy: (1 [D]) I took pride in driving well even when I was young, for I had to wait until I had a car to learn to drive, When I finally learned, it was something I really enjoyed and still enjoy.
Interviewer: I see. And how long have you been a taxi driver?
Nancy: Err...altogether 12 years.
Interviewer: Mm…It has been quite some time already, hasn’t it?
Nancy: Yeah.
Interviewer: Then, what did you find the hardest about becoming a taxi drive
Nancy: It was scary. (2[B]) I did not yet know how to judge distance, and when a truck came nearer, it seemed like its wheels would just come right over me. Anyway, soon I learned it all and stopped worrying.
Interviewer: In your opinion, what does ii take to become a good taxi driver?
Nancy: Err...besides driving well, (3[B]) the most important thing a taxi driver needs to know is the streets, and I knew the city well because I’d lived there for a long time. And, of course, you have to keep updating your knowledge of the streets because the city changes.
Interviewer: Now, what about annual vacation? Do you have them?
Nancy: Oh, yes. When I first started, I had only 10 days. And now I have 3 weeks every year with pay.
Interviewer: Just out of curiosity, when you go on vacation to another place, do you drive there as well?
Nancy: In most cases, not. (4[C])I prefer to be driven by others if we go by car. I’ve had too much driving in my life. So when on holiday, I just want to relax.
Interviewer: OK. Our interview is coming to the end. Thank you for your time.
Nancy: Pleasure.
