In more than a century of hand-to-hand combat in shops, supermarket aisles, restaurants and bars around the world, Coca-Cola has nearly always been in the lead and Pepsi in second place. When Warren Buffett, Coke’s long-time investor, told the board that he had visited a pizza parlour in Omaha, Nebraska, with his grandson only to discover it served nothing but Pepsi, Coke’s bosses acted swiftly to remove their arch-rival from the menu and replace it with Coke.
If only the Atlanta-based company had moved as determinedly in response to changing consumer tastes, it might have avoided a humiliating reversal in fortunes. On December 12th PepsiCo overtook Coca-Cola in market capitalisation for the first time. With PepsiCo’s share price having risen by 14% this year, its stock market value reached $ 98.4 billion, compared with $ 97.9 billion for Coca-Co la, which has seen its shares decline by 1.2% in the same period.
Pepsi is powe
A. to keep healthy.
B. to remain stronger.

More than two centuries after Benjamin Franklin used one to study lightning, a team of atmospheric scientists has found that kites are a potent research tool for studying air conditions at high altitudes.
Ben Balsley and John Briks at the University of Colorado have developed a kite and instrument package to sample the atmosphere up to 3.5 kilometers high, for up to two days at a time. The kite is cheaper and more flexible than balloons and aircraft, the traditional vehicles for atmospheric research. Within two years the team expects to fly kites up to 10 kilometers high, and Briks hopes to use these to measure carbon dioxide and methane emissions over the Brazilian rainforest and the transport of air pollutants over the Atlantic Ocean.
The kite is a 15-square-meter Para foil made of Mylar, which ’is not only strong, but unlike nylon, Joes not absorb water. The kite "string" is made of Kevlar, famous for its use in bullet-proo
A. Kites have been found to be a useful tool in research on air conditions
B. Balloons and aircraft are traditional tools in research on air conditions
C. C .The kites can now fly up to 10 kilometers high
D. The kites are expected to fly higher and do more researches in the near future
