passage 1
 The company’s new formula was designed partly to keep Coke’s sales growing overseas. Compared with Americans, who guzzle more soda than water, the rest of world is still in the sipping stage. Coca-Cola’s goal is to kick up its slowing growth rate outside the U.S. from about 3% a year to 10%. Company executives think a less filling, more “guzzleable” new Coke will help.
 Domestically, sales of soft drinks have been bubbling a long nicely. They grew 6% last year, vs. 2% to 3% a few years ago. But the cola makers may experience more growing pains, at least with the high-calorie colas that acfor half of all sales (diet colas hold about 12%). Baby-boomers are showing a strong preference for healthier, less fattening drinks as they age-every-thing from diet soda to bottled water to fruit juice.
