It seems that no matter how many times we clean up the dust in our houses, it just keeps coming back. While it may seem like you are doing everything that you can to keep the dust out, a new layer always appears, especially on electronics. ¨ç Most household dust doesn't come from outside; it comes from inside. ¨è The majority of household dust comes from us humans. ¨é Humans lose millions of skin cells every day, and this skin cells fall from our bodies in tiny grey flakes. ¨ê While they are too small to see individually, as they begin to build up on surfaces, they create the grey layer that is so familiar. ¨ë The outer layer of the skin is called the epidermis. Statistics suggest that people lose half a kilogram of skin each year, and this skin builds up all around the house. A smaller portion of dust can come from outside if the house is not fully sealed. Any time a window is open, particles of dirt and soil can be carried on the wind and blown into the house. In addition, the pollen from plants can create dust around the house.
5. Which of the following is correct according to the passage?(1ºÐ)
Arches have been used since ancient civilizations, such as the Romans, discovered the architectural benefits of the structure. Arches are widely used even today to support large amount of weight, and they seem to defy gravity. How can an arch support so much weight without falling down? The secret is in how they are built. Arches must first begin with a wooden frame that will support the individual pieces of the arch as it is being built. Then, a series of wedge-shaped blocks are placed onto the frame, beginning toward the outsides of the frame and working toward the center. Once the blocks are placed on each side, one more block must be added to the middle. This block is called the keystone, and it is the secret behind the arch's ability to stay together. The keystone exerts a force upon each side of the each, pushing each successive block into the next. This provides a great deal of friction, which keep the blocks from sliding away from one another. Thus, the wooden frame can be removed, and the arch will stay together.
¨ç The frame must be removed before placing the keystone.
¨è Blocks are added to an arch from one side to the other.
¨é Arches were first used by the ancient Romans.
¨ê The central block of an arch is called a keystone.
¨ë An arch's strength is due to its wooden frame
