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: Australian scientists say an organic compound used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer. Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma , a type of skin cancer. More than 1,200 Australians die every year from the disease. Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment. "We believe it works by getting into the tumor cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It's not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision ,"he said. "It's useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred." About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal. Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging. Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg. "I've had a lot of friends who just said 'I thought it was just, you know, I'll get a mole cut out and that's it', whereas I don't think people realize how much danger they're putting themselves into and how easy it is to stop something like this happening to you just from doing little things,"said Marock. Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned , are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.
Question: The information about Rose Bengal is wrong EXCEPT that _ .
Options: (A) it is no longer used as a dye (B) it is used to cure skin cancer (C) it is a special kind of rose planted in Australia (D) it can be effective in treating skin cancer
Asnwer: D
Example Output: Yes

Example Input: Article: Nuclear weapons were first developed in the United States during the Second World War to be used against Germany.However, by the time the first bombs were ready for use, the war with Germany had ended and, as a result, the decision was made to use the weapons against Japan instead. The real reasons why bombs were dropped on two heavily populated cities are not altogether clear.A number of people in 1944 and early 1945 argued that the use of nuclear weapons would be unnecessary, since American Intelligence was aware that some of the most powerful and influential people in Japan had already realised that the war was lost, and wanted to discuss a Japanese surrender .It was also argued that, since Japan has few natural resources, a blockade by the American navy would force it to surrender within a few Weeks, and the use of nuclear weapons would prove unnecessary.If a demonstration of force was required to end the war, a bomb could be dropped over an unpopulated area like a desert, in front of Japanese observers, or over an area of low population inside Japan, such as a forest.Choosing this course of action might decrease the loss of further lives on all sides, while the power of nuclear weapons would still be adequately demonstrated . All of these arguments were turned down, however, and the general agreement was that the quickest way to end the fighting would be to use nuclear weapons against the centres of population inside Japan.In fact, two of the more likely reasons why the decision was reached seem quite shocking to us now.
Question: According to Paragraph 2, a blockade would have been successful because
Options: (A) Japan had to import most of its natural resources (B) Japan would not be powerful enough to beat a blockade (C) an attack would probably destroy Japanese resources within a few weeks (D) the Americans could defeat Japan's navy since it was short of resources
Asnwer: D
Example Output: No

Example Input: Article: To the untrained eye it might seem like just a bit of a monkey trick. But when Milly the mandrill (, ) covers her face with her hand she is actually sending a serious message to her fellows: "Leave me alone!" Experts believe the 15-year-old mandrill invented the gesture to warn other monkeys at Colchester Zoo to give her some space. And, surprisingly, the signal has been picked by other members of the group, who use it when they too require _ . Biologist Mark Laidre believes the behavior is evidence of social culture among the mandrills. Importantly, the sign language is unlikely to have been influenced by human activities because mandrills do not copy humans. Mr. Laidre expects further research will uncover other monkeys using cultural gestures -- the ability to communicate with the hands in a meaningful way. "By covering their eyes with their hands, possibly conveyed to others that they wanted to be left alone and this message may have been respected as a 'do not disturb' sign," said Mr. Laidre. While the hand is in place, other monkeys are not likely to approach or touch the monkey. Those who rank lower in the social order also use the technique to avoid attacks from more powerful group members. As the discovery appears to be unique to Colchester Zoo, it suggests it is a local phenomenon that arose naturally in the community of 25 mandrills. Curator Sarah Forsyth said: "We believe Milly made up the signal and over the past five years some of the younger mandrills have picked it up. We're not sure why she started doing it but it could be as simple as 'I can't see them, so they can't see me'. It really does show you how intelligent mandrills are."
