[EX Q]: Article: A lot of people these days believe Valentine's Day is a made-up holiday designed to promote the sale of greeting cards and gifts. And while there may be some Arguments for that, there is a mysterious story as to why February 14th has become known today as "Valentine's Day." Our story dates back centuries ago, to the Roman Empire, and the martyrdom   of two or three Christians named Valentine. At least one of those Valentines is thought to have been killed on February 14th. Legend has it that this particular Valentine wais killed by a Roman emperor because he secretly presided   over the marriages of young men and women, against the wishes of the Emperor, who wanted only single men to fight in his army. However, there is no historical evidence to back this up. But what is widely known is that the love-element to Valentine's Day can be first traced   to the poetry of Geoffrey Chaucer. Chaucer wrote a poem in 1382 to mark the anniversary of his King's engagement, and scribed a line -- "For this was Saint Valentine's Day, when every bird cometh there to choose his male." From this point, on Valentine's Day became intertwined with love. But for the pessimists out there who see Valentine's Day as a commercial idea, there is some historical evidence to back this up as well! The true popularization   of Valentine's Day can be traced to late 18th century England, when a British publishing company first started selling paper Valentine's Day cards with tender words on them. They became so popular that by the middle of the 19th century, some 1.3 billion British pounds a year were being spent on Valentine's Day gifts.

[EX Q]: Article: There is some unwelcome news for students preparing for exams and officers putting in long hours-----you don't need the break as much as you may think that makes you feel less tired. Scientists have long assumed that willpower   is a limited resource, which is why you feel the need to have a rest, have a snack and come back to a task when you're feeling better. They argued that the only way to restore willpower was by rest, food or entertainment. But psychologists have challenged this theory, saying weak willpower is all in your head. They found that people's beliefs in willpower determine how long and how well they'll be able to work on a tough mental exercise. "If you think of willpower as something that's limited, you're more likely to be tired when you perform a difficult task," said Prof.Veronika Job. "'But if you think of willpower as something that is not easily used up, you can go on and on." The researchers designed four experiments to test students'-beliefs in willpower. After a tiring task, those, who believed or were led to believe that willpower is a limited resource, performed worse on standard concentration tests than those who thought of willpower as something they had more control over. They also found that leading up to final exam week, students who believed the limited resource theory ate junk food 24 percent more often than those who believed they had more control in resisting temptation  . Mr. Job said. "The theory that willpower is a limited resource is interesting, but it has had unintended consequences. Students who may already have trouble studying are being told that their power of concentration is limited, and they need to take frequent breaks. But a belief in willpower as a non-limited resource makes people stronger in their ability to work through challenges.'" The findings could help people who are" battling temptation. Willpower isn't driven by a biologically based process as much as we used to think. The belief in it is what influences your behavior. 
 Question: The theory that willpower is limited supports that   _  . 
 Options: (A) people must eat snacks when they feel tired (B) people do need a break to restore their willpower (C) there's no way to strengthen people's willpower (D) weak willpower doesn't affect people's life much
