Read the passage and answer the following:
FINDING A JOB

Not so long ago almost any student who successfully completed a university degree or diploma course could find a good career quite easily. Companies toured the academic institutions, competing with each other to recruit graduates. However, those days are gone, even in Hong Kong, and nowadays graduates often face strong competition in the search for jobs.

Most careers organizations highlight three stages for graduates to follow in the process of securing a suitable career: recognizing abilities, matching these to available vacancies and presenting them well to prospective employers.

Job seekers have to make a careful assessment of their own abilities. One area of assessment should be of their academic qualifications, which would include special skills within their subject area. Graduates should also consider their own personal values and attitudes, or the relative importance to themselves of such matters as money, security, leadership and caring for others. An honest assessment of personal interests and abilities such as creative or scientific skills, or skills acquired from work experience, should also be given careful thought. The second stage is to study the opportunities available for employment and to think about how the general employment situation is likely to develop in the future. To do this, graduates can study job vacancies and information in newspapers or they can visit a careers office, write to possible employers for information or contact friends or relatives who may already be involved in a particular profession. After studying all the various options, they should be in a position to make informed comparisons between various careers.

Good personal presentation is essential in the search for a good career. Job application forms and letters should, of course, be filled in carefully and correctly, without grammar or spelling errors. Where additional information is asked for, job seekers should describe their abilities and work experience in more depth, with examples if possible. They should try to balance their own abilities with the employer’s needs, explain why they are interested in a career with the particular company and try to show that they already know something about the company and its activities. When graduates are asked to attend for interview, they should prepare properly by finding out all they can about the prospective employer. Dressing suitably and arriving for the interview on time are also obviously important. Interviewees should try to give positive and helpful answers and should not be afraid to ask questions about anything they are unsure about. This is much better than pretending to understand a question and giving an unsuitable answer. There will always be good career opportunities for people with ability, skills and determination; the secret to securing a good job is to be one of them.

Question: In paragraph 3, ‘three stages for graduates’ refers to:

A. all of the above
B. stages in the assessment of personal interests
C. stages in the process of securing a suitable career
D. stages for the completion of a university degree or diploma course .
