[单项选择]
Pisa is an Italian city known for its Leaning Tower.
The Tower, interestingly enough, started leaning in the middle of its construction — when its first three stories were completed. Bonnano Pisano, the engineer in charge, tried to correct the lean by making the new stories slightly taller on the short side, only to find that the added marble caused the Tower to sink still further. Work was suspended several times as engineers sought fresh solutions, until the Tower was finished in the 14th century, still leaning. The construction, begun in 1174, nearly took 200 years.
In modern times the structure has been several times strengthened by cement, but to this day it is still in danger of collapse. Various schemes have been under consideration for saving, it. To rebuild an upright tower would be easy enough for modern engineering, but it would not be the same edifice as people love and remember it. The Leaning Tower must be left leaning, saved, not reconstructed
A. It makes its city Pisa well-known.
B. Its construction took nearly 200 years.
C. Many measures have been taken to correct the lean.
D. If you go to Pisa now, you can go and visit the Leaning Tower.
