Article: It often happens that a number of applicants with almost the same qualifications and experience all apply for the same position. In their educational background, special skills and work experience, there is little, if anything, to choose between half a dozen candidates. How then does the employer make a choice? Usually on the basis of an interview. There are many arguments for and against the interview as a way of selection. The main argument against it is that it results in a wholly _ decision. As often as not, employers do not choose the best candidate. They choose the candidate who makes a good first impression on them. Some employers, of course, reply to this argument by saying that they have become so experienced in interviewing staff that they are able to make a good assessment of each candidate's likely performance. The main argument in favor of the interview is that an employer is concerned not only with a candidate's ability, but with his or her suitable personality for the particular work situation. Many employers, for example, will overlook occasional mistakes from their secretary if she has a pleasant personality. It is perhaps true to say, therefore, that the real purpose of an interview is not to assess the assessable aspects of each candidate but to make a guess at the things that are hard to measure, such as personality, character and social ability. Unfortunately, both for the employers and applicants for jobs, there are many people of great ability who simply do not interview well. There are also, of course, people who interview extremely well, but are later found to be very unsatisfactory employees. Candidates who interview well tend to be quietly confident, but never boastful , direct and straightforward in their questions and answers; cheerful and friendly, but never over-familiar; and sincerely enthusiastic and optimistic. Candidates who interview badly tend to be either very shy or over-confident. They either talk too little or never stop talking. They are either over polite or a bit rude.
Question: People argue over the interview mainly because they have _ .
Options: (A) different purposes in the interview (B) different experiences in interviews (C) different standards of selection (D) different ways of selection

Article: My first day of high school was like any other first day: registering, finding new classmates, meeting new teachers, and seeking new friends. During lunch, I ran into my first snag of the day. At the dining hall, as the checkout lady asked for my money, I realized that I had forgotten my money. When I told her about it, I heard a voice behind me. I turned around and there stood a teacher telling her he will pay for my lunch. He told me his name was Mr. Peter Walker, and said, "If you get a chance, you should take my history class." I recognize his name, and told him I was in his class later that day. Mr. Walker befriended me on the very first day of school at a very crucial time of the day---lunch! He always told us we should do more than we ever thought. He pushed us to do all things better. He coached many sports, and sponsored many after class activities. If we were interested in something, he would find a way to expose us to it, say, inviting speakers, taking us on field trips, or obtaining information for us. Two years later, my junior year in school was clicking along nicely when one day I was riding my motorcycle and I was hit by a car. I spent six days in hospital and was at home in bed for two weeks before returning to school. Mr. Walker stopped by the hospital each day with my work from my teachers. Once I was at home, he would bring my work too. After high school, I attended the United States Army Airborne School in Georgia. I knew my parents would be there the day I graduated, but they brought an unexpected guest. They came across Mr. Walker at lunch several days before and told him I was about to graduate. His visit, however, was not a surprise to me.
