Hollywood has a message for scientists: If you want something that’s 100% accurate in every way, go watch a documentary. The thing is, when it comes to movies, narrative wins. The writer’s job is to get the characters right, not the science, says Tse, who cowrote Watchmen, one of last year’s most-anticipated superhero films. It annoys him, too, when things don’t make sense. He spent a lot of time and energy trying to find a fix for a logical problem in Watchmen--that one character, Dan, uses a completely obvious password to hack into the computer of Adrian, who is supremely intelligent. But for practical reasons, that kind of problem often just can’t be fixed. Maybe it would take too long, in an already long movie, or distract too much from the narrative, or cost too much to shoot. Writers have faced similar problems with the TV show Heroes. The series follows a group of characters that have acquired superpowers: one is invisible, and one can walk through walls. One little boy can control electronics with his mind, which is "completely scientifically crazy," says Joe Pokaski, a writer who has worked on every one of the show’s 76 episodes. But scientific sense isn’t necessarily the point. As long as things make sense to the viewer, that’s good enough, and it can leave the show open to carry out its real business: exploring the characters’ struggle to figure out how to use their powers. And don’t even get Heroes writer Aron Coleite started on invisibility. In a scene from the first season of the show, two invisible men walked down a Manhattan street, bumping into people and things as they went. Coleite says, "We spend hours in a smelly room arguing about invisibility." Questions such as: Does invisibility extend to clothes Should the guys be walking down the street naked "We’re demonstrating it visually. We don’t bother people with saying, ’It’s an invisible field around them that blocks light, and that’s why Claude is wearing clothes’," Coleite says. All of this makes sense when you consider that most of these writers don’t have Ph.D.s in astrophysics (天文地理学). "You asked if we had a science background," said Pokaski, "No, we have a science fiction background. The more you try to explain, the sillier it sounds.\ What do we know about Hollywood documentaries

There was a time, not that long ago, when women Were considered smart if they played dumb to get a man, and women who went to college were more interested in getting a "Mrs.degree" than a bachelor’s. Even today, it’s not unusual for a woman to get whispered and unrequested counsel from her grandmother that an advanced degree could hurt her in the marriage market. "There were so many misperceptions out there about education and marriage that I decided to sort out the facts," said economist Betsey Stevenson, an assistant professor at the Wharton School at the University of Pennsylvania. So along with Wharton colleague Adam Isen, Stevenson calculated national marriage data from 1950 to 2008 and found that the marriage penalty women once paid for being well educated has largely disappeared. "In other words, the difference in marriage rates between those with college degrees and those without is very small," said Stephanie Coontz, a family historian at Evergreen State College. The new analysis also found that while high-school dropouts(辍学学生) had the highest marriage rates in the 1950s, today college-educated women are much more likely to marry than those who don’t finish high school. Of course, expectations have changed dramatically in the last half century. "In the 1950s, a lot of women thought they needed to marry right away," Coontz said. "Real wages were rising so quickly that men in their 20s could afford to marry early. But they didn’t want a woman who was their equal. Men needed and wanted someone who knew less." In fact, she said, research published in 1946 documented that 40 percent of college women admitted to playing dumb on dates. "These days, few women feel the need to play down their intelligence or achievements," Coontz said. The new research has more good news for college grads. Stevenson said the data indicate that modern college-educated women are more likely to be married before age 40, are less likely to divorce, and are more likely to describe their marriages as "happy". The marriages of well-educated women tend to be more stable because the brides are usually older as well as wiser, Stevenson said. According to the first paragraph, what grandmother whispers to her granddaughter is usually ______.

A. taken as a warning
B. regarded as out-of-date
C. given voluntarily
D. accepted unwillingly
