"Racism   is a grown-up disease," declares the saying on Ruby Bridge's website along with a photo of Mrs. Bridge today, a 6-year-old girl four decades ago. In the photo, she is walking up the steps of the William Frantz Public School in New Orleans, a little black girl accompanied by two officers who protect her on her way to school. Her name then was Ruby Nell. It was Nov. 14, 1960. She was the first black child to enroll at this all-white elementary school according to the court order to desegregate in New Orleans schools. Her story is moving -- she was a very courageous child -- and remains a significant proof against intolerance   of all kinds. Ruby's photo brings out another powerful image on her website: Norman Rockwells symbolic painting for Look magazine on Jan. 14, 1964, "The Problem We All Live With." Rockwell was an illustrator of exceptional skill and charm. He produced a vast number of unforgettable images over a long career, many of them involving children. His American kids are innocent and appealing, but often, at the same time, decidedly naughty. His method was to photograph his models, and the resulting paintings were photographic. But it is revealing to see how the artist slightly changed facial expressions from photo to oil painting in order to make his paintings communicate with the viewer. Communication, even persuasion, lay at the back of his work; this was art for effect. "The Problem We All Live With" belongs to Rockwell's later work, when he began openly showing his strong belief in liberty. This is a highly persuasive image. Before he arrived at the final copy, one sketch   shows the little girl closer to the two officers following her than to those in front. In the finished picture, the girl seems more determined, independent, and untouched. The unfriendly tomatoes thrown on the wall are behind her now, and she, is completely unaffected. The main topic of this passage is  _  . A) how Rockwell encouraged Ruby to fight against racism B) how Ruby won her fight to go to an all-white school C) how Rockwell expressed his protest in .Iris work D) how persuasive Rockwell's earlier work of art is

NEW YORK---One in five U.S. workers regularly attends after-work drinks with coworkers, where the most common mishaps range from badmouthing another worker to drinking too much, according to a study released on Tuesday. Most workers attend so-called happy hours to bond with colleagues, although 15 percent go to hear the latest office gossip and 13 percent go because they feel necessary, said the survey conducted for CareerBuilder. com, an online job site. As to what happens when the after-work drinks flow, 16 percent reported bad-mouthing a colleague, 10 percent shared a secret about a colleague and 8 percent said they drank too much and acted unprofessionally. Five percent said they had shared a secret about the company, and 4 percent confessed to singing karaoke. While 21 percent of those who attended said happy hours were good for networking, 85 percent said attending had not helped them get closer to someone higher up or get a better position.
