In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.

Example Input: Article: The U. S. Postal Service (USPS) is losing billions of dollars a year. The government company that delivers "small mail" is losing out to email and other types of electronic communication. First-class mail amount fell from a high point of 104 million pieces in 2000 to just 64 million pieces by 2014. Congress permits the 600.000-empIoyee USPS to hold a monopoly over first-class and standard mail. The company pays no federal, state or local taxes; pays no vehicle fees; and is free from many regulations on other businesses. Despite these advantages, the USPS has lost $52 billion since 2007, and will continue losing money without major reforms. The problem is that Congress is preventing the USPS from reducing costs as its sales decline, and is blocking efforts to end Saturday service and close unneeded post office locations. USPS also has a costly union-dominated workforce that slows the introduction of new ideas or methods down. USPS workers earn significantly higher payment than comparable private-sector workers. The answer is to privatize the USPS and open postal markets to competition. With the rise of the Internet, the argument that mail is a natural monopoly that needs government protection is weaker than ever. Other countries facing declining letter amounts have made reforms Germany and the Netherlands privatized their national postal companies over a decade ago, and other European countries have followed suit. Britain floated shares of the Royal Mail on its stock exchange in 2013. Some countries, such us Sweden and New Zealand, have not privatized their national postal companies, but they have opened them up to competition. These reforms have driven efficiency improvements in all of these countries. Additional number of workers have been reduced, productivity has risen and consumers have benefited. Also, note that cost-cutting measures--such as closing tone post offices--are good for both the economy and the environment. Privatization and competition also encourage new changes. When the USPS monopoly over "extremely urgent" mail was stopped in 1979, we saw an explosion in efficient overnight private delivery by firms such as FedEx. The government needs to wake up to changing technology, study postal reforms abroad and let businessmen reinvent our out-of-date postal system.

Example Output: No

Example Input: Article: In South Korea, children get used to the Internet at an early age. A survey last year by the Ministry of information and Communication showed that nearly half of children between the age of 3 and 5 use the internet. "In south Korea, _ , said Lee Kyong Ko, a professor at Duksing, Women's University in Seoul. Online role-playing games, where participants make friends and band together, have a strong appeal to Koreans,"One problem with those games is that you build your online person through countless hours of battles, and you develop a huge emotional attachment to your game character,"said Chang Woo Min, a one-time online gamer. Parents report that their children steal money and do not come home for days and even weeks, practically living in Internet Cafes, and sometimes they refuse to look for jobs and play games all night and sleep during the day. The authorities require Internet cafes to keep their distance from schools, and they open camps for teenage addicts and distribute booklets on the dangers of game addiction. In addition, they are training hundreds of counselors, who visit schools and Internet Cafes. In the 28,000 Internet Cafes in South Korea, persons under 18 are banded from entry after 10 p.m.. The authorities have even discussed reducing the points of gamers who play for more than three consecutive hours, But such talks have produced no agreement, amid concerns that such restrictions would put a high-growth industry in danger and worse the problem of teenagers stealing adult online identification numbers,"Sooner or later we will be able to announce our measures,"the minister of Information and Communication, Rho Jun Hyoung, said at a news conference in May."Since South Korea is one of the most active and developed countries in the Internet, the world is paying great attention to What policy we will adopt on this problem."

Example Input: Article: WASHINGTON -- Patients with HIV, the virus that causes AIDS, often develop vitamin deficiencies . A new study has found that giving these patients a multivitamin with a mineral supplement helps to fight the disease and slows the disease's progression. Sub-Saharan Africa has always been the center of the AIDS. In Botswana, despite aggressive prevention campaigns, one out of every four adults is infected with HIV. Professor Marianna Baum based her latest research there. Baum recruited almost 900 newly infected adults who had not yet received the anti-AIDS drugs that target the virus. These adults were then divided into groups that randomly received different combinations of vitamins B, C and E, the mineral selenium or a placebo . Most patients with HIV become deficient in these vitamins, which help improve immunity . Baum said she initially thought the multivitamins alone or selenium alone would be effective in strengthening the immune system, but found that incorrect. "We were surprised to find that only the combination was effective," said Baum. Research shows that when people with HIV receive anti-retroviral drugs shortly after infection, they can remain healthy and are less likely to pass the virus to others. For many countries, however, the cost of these anti-AIDS drugs is still prohibitive. Baum said the vitamin and mineral combination treatment should help low income countries better control the virus. "A simple multivitamin supplementation with selenium provided early in HIV disease can actually slow the HIV disease progression and it is safe. It is low cost and it should be provided very early in HIV infection," said Baum. Baum said the supplements are not meant to replace anti-retroviral therapy, but can help those who cannot obtain the drugs. Dr. Anthony Fauci, a world famous expert on AIDS, disagrees. "I haven't read the paper, but having taken care of HIV-infected individuals for three decades, I would doubt that vitamins are going to have a major effect on stopping the virus," said Fauci. Fauci said vitamin and mineral supplements may make a patient generally healthier, but the only thing that truly works to stop HIV is anti-retroviral treatment. Baum's study was published in the Journal of the American Medical Association.
