Article: Dogs can know the meaning of a human perspective, say researchers. Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers. They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see. This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed. The study, published in Animal Cognition, conducted tests on eighty-four dogs. The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human. It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food. The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them. Juliane Kaminski carried out the research into how dogs are influenced by human circumstances. Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective". Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions. "Humans constantly attribute certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them," said Dr Kaminski. "These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly... Question: This passage can be classified as _ .

Article: Days after celebrations honoring his bicentennial , Abraham Lincoln kept his rank as best US president, according to a survey of 65 historians that landed George W. Bush 36th out of 42 overall. Abraham Lincoln (1861-1865), the first US president George Washington (1789-1797) and New Deal architect Franklin D. Roosevelt (1933-1945) were ranked the top three out of the 42 men who have been the country's former chiefs, according to a survey by cable channel C-SPAN. John F. Kennedy came in sixth, ahead of Ronald Reagan (10th) and Bill Clinton, who jumped to 15th from 21st during the last survey in 2000, when prefix = st1 /Lincolnalso ranked first. Of all modern presidents, Bush, who left office last month after an eight-year term, behaved worst at 36th, nearly 10 spots behind Richard Nixon (27th), who was forced to resign in disgrace in consequence of the Watergate Scandal .

Presidents James Buchanan, Andrew Johnson, Franklin Pierce and William Henry Harrison ranked worst overall. Question: What's the best title for the above passage?
