Example Input: Article: In Western countries people have been using the installment plan since the first half of the twentieth century. Today, a large number of families in Great Britain buy furniture, household goods and cars by installments .In the U.S., the figure is much higher than in Great Britain, and people there spend over 10 percent of their income on the installment plan. The price of an article bought on installments is always higher than the price that would be paid by cash. There is a charge for interest. The buyers pays one quarter or one third of the price as a down payment when the goods are delivered to him. He then makes regular payments, weekly or monthly, until the full price is paid up. The legal ownership of the goods remains with the seller until the final payment has been made. Installment buying has advantages and disadvantages. It can help couples with small incomes to furnish their homes and start housekeeping, It increases the demand for goods, and in this way helps business and employment. There is ,however, the danger that when business is bad, installment buying may end suddenly, making business much worse. This may result in a great increase in unemployment. If the people on the installment plan lose their jobs, they will probably not be able to make their payments. If great numbers of people are not able to pay their installment debts there is a possibility that businessmen cannot collect their debts and will therefore lose money. If businessmen lose money or fail to make a satisfactory profit, it becomes more likely to have a depression. This is why, in some countries, the government controls the installment plan by fixing the amount of the down payment to discourage people from buying more than they can pay for on the installment plan.
Answer: The payment of installment buying is easier than buying by cash.
Example Output: Which of the following is true about the installment plan?

Example Input: Article: Spring is coming, and it is time for those about to graduate to look for jobs. Competition is tough, so job seekers must carefully consider their personal choices. Whatever we are wearing,our family and friends may accept us, but the workplace may not. A high school newspaper editor said it is unfair for companies to discourage visible tattoos nose rings, or certain dress styles. It is true you can't judge a book by its cover, yet people do "cover" themselves in order to convey certain messages. What we wear, including tattoos and nose rings, is an expression of who we are. Just as people convey messages about themselves with their appearances, so do companies. Dress standards exist in the business world for a number of reasons, but the main concern is often about what customers accept. Others may say how to dress is a matter of personal freedom, but for businesses it is more about whether to make or lose money. Most employers do care about the personal appearances of their employees ,because those people represent the companies to their customers. As a hiring manager I am paid to choose the people who would make the best impression on our customers. There are plenty of well-qualified candidates, so it is not wrong to reject someone who might disappoint my customers. Even though I am open-minded, I can't expect all our customers are. There is nobody to blame but yourself if your set of choices does not match that of your preferred employer. No company should have to change to satisfy a candidate simply because he or she is unwilling to respect its standards, as long as its standards are legal.
Answer: What to wear is not a matter of personal choice for companies.
