A、Resort to the Part-time Job Center. B、Turn to their professor for help. C、Hire a professional with better pay. D、Pay her full

M: Hi Jane, please come in and take a seat.
W: Well, you would like to check the progress of the website-design, right?
M: Yes, but it seems that we’ve got some problems with the BBS. [19]The part-time web designer was not as good as what we had thought before. She informed us just now that she could not complete this task.
W: Well, didn’t you talk with her about what she should do at the beginning?
M: Not really. [20]She was recommended by Sampson and from what he told me, she sounded to be pretty qualified to do the job. I’m not asking for a terrific web design but to build up a structure with all the basic elements of web design.
W: Did you ask her why she wasn’t frank with you in the beginning if [19]she couldn’t do the BBS?  
M: I did. [21]But she said it was a communication problem.
W: So now what do you plan to do since she got the job half done?
M: On one side, I will not pay her full fees since she wasn’t honest with me in the beginning. On the other side, I have to search around for another guy to complete the job.
W: I agree. That should also teach her a lesson. For us, [22]I think we had better turn to our Part-time Job Center for help. There, we can get a professional to work at it.
