问题     Termites are social insects like ants, living in well-organized colonies established and centered around a queen and her mate. The queen’s chief function is to lay eggs. Termites of a worker caste, white in color, tend the eggs and young and go forth to find food. Other termites form a soldier caste; they are white also but have larger heads than the workers. In the spring, young queen and king termites-brown or black in color--fly from the nest and enter the ground to mate and start new colonies.
    The colonies are underground because the soil provides moisture the termites need to sustain life. A worker dining on a tasty door frame, for example, may make several trips below ground daily, both to bring food to the colony and to replenish its own moisture supply. If its retreat to earth is cut off, it will die. In brief, termites only go into wooden structures to eat. They can’t move in and set up housekeeping there unless they find a supply of water, as from a plumbing leak in a wall. Almost every, termite infestation begins with a colony based in the soil. If you have a way of keeping the pests underground, you don’t have to worry about them.
What do termites feel the most important to consider before they move in the wood structure?
选项 A、Food.
B、Housekeeping.
C、Soil.
D、Water supply.
答案D
解析 第二段最后。白蚁只吃木制建筑，但又不能把家安置在那里。除非有水的保证，比如墙中有管道漏水。所以在它们考虑是否进入这座木制建筑物之前，有没有水是最重要的。选项D是正确的。
