阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。
Forces other than damaging winds are also at work inside tornadoes(龙卷风). Sometimes, as the wind passes a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion is caused by the low air pressure at the center of a tornado.
The pressure at the center of a tornado is usually 13 pounds per square inch. However, inside the house the air pressure is normal, about 15 pounds per square inch. The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado passes over a small building that measures 20 by 10 by 10 feet. On each square inch of the building, there is 2 pounds of pressure from the inside that is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57,600 pounds. The pressure of the four walls adds up to 172,800 pounds.
If windows are open in the building, some of the inside air will rush out through them. This will balance the pressure inside and outside the building. But if the windows are shut tightly, the huge inside pressure may cause the building to burst.
Unfortunately, heavy rain often occurs in the storms that later produce tornadoes, so people often shut their windows. This may cause far worse damage later.
What did the paragraph before this passage most probably discuss__1__
A. Measuring rainfall from a storm.
B. The kinds of damage caused by explosions.
C. The powerful winds of tornadoes.

C. Why tornadoes cause so much damage.
3. Tornadoes can destroy buildings because the________.__3__
A. force of a tornado increases the air pressure in a building
B. air pressure inside a tornado is less than the air pressure inside a building
C. air pressure at the center of a tornado is over 172,000 pounds
4. What is the difference per square inch between the air pressure inside a building and the air pressure inside a tornado__4__
A. 2 pounds. B. 13 pounds. C. 15 pounds.
5. What would happen if the windows are shut tightly in the stormy weather__5__
A. Tornadoes may be formed.
B. The house may burst apart.
C. There may not be any pressure inside the building.__5__(完形填空)
