根据短文内容，判断下列句子的正误，正确的用“T”，错误的用“F”。
        It takes only 30 seconds to finish the journey in the South Pole. Visitors to the South Pole like to walk
around, so there is a clear path in the snow there. Some visitors are so excited that they stand on their heads
and have their pictures taken with flags of the Antarctic countries in the background.
        The United States has kept a base in the South Pole since 1956. Chinese scientists and technological
engineers have built an observation station there, too.
        The South Pole itself is marked by a two-meter bamboo pole stuck in the ice. The ice cap (冰盖), which
is 2,850 meters thick, moves 12 meters a year in the direction of Buenos Aires, Argentina. So the bamboo pole
has to be moved back the same distance.
        The air in the South Pole is the cleanest on earth. Scientists from different countries have been working
on making the Antarctic a world park to save it from being polluted by the wrong use of its oil and other
mineral resources.

[ ]
A. there is a clear path in the snow there
B. it doesn't take long to finish the journey there
C. the weather there is suitable for visitors to do so
D. the air there is the cleanest on earth
2. Which of the following is RIGHT?
[ ]
A. People spend much time visiting the South Pole.
B. Two observation stations were built in the South Pole in 1956.
C. The air in Argentina is much cleaner than that in the United States.
