In these times, the pressure of job-hunting has clearly increased, which causes the critical unemployment of graduates.Many graduates’ failing to find a job has four main reasons. On the one hand, the economy is in recession, causing the decrease of available jobs. On the other hand, the number of graduates is growing, so the competition for job-hunting is increasingly fierce.Meanwhile, some students just have no idea of which job to apply for. What makes things worse was that a large number of students prefer to be unemployed rather than apply for jobs with low salaries. As far as I am concerned, graduates shouldn’t bite off more than they can chew. Having a just passable job is better than getting stuck at home at any case. Last but not least, they should keep optimistic and avoid being decadent, trying their best and catching every opportunity to hunt for a job.Question: Which is wrong?

A. late for work
B. be responsible.
C. dress formally
D. good team player
