In North America, for example, many people build their houses of wood. There are large areas of forests, so wood is easy to get and inexpensive. In countries around the Mediterranean Sea, there are few forests, so people use other materials, especially stone and brick. In tropical areas of Africa and Asia, people do not need thick walls, so they build houses with other kinds of material, like bamboo and other plants. Finally in extremely cold climates such as northern Canada and Alaska, the only material that is easily available is ice. Until recently, people made houses from blocks of ice (though now they use other materials). (a) What is the topic of this paragraph?

Yоur cоmpаny is аn insurаnce underwriter, writing insurance pоlicies on a variety of events. You have the following risk matrix, with the likelihood of the events on the left side, and the consequence (in expenses, in millions of USD) along the top. Assume the likelihood of each event is independent of its consequence. Final Exam Q2.png  We are going to use the Risk = Probability x Consequence measurement here. Scenario 1 (hurricane hits small town) has a likelihood of 0.5% and a consequence of $11 million. What is its total risk value? Enter your answer rounded to the whole integer and leave off any currency signs. For example, if you compute $1,234.56 as your answer, you will enter 1235.
