Answer to Question 1

Answer: B

Answer to Question 2

Answer: The enhanced Fujita scale is a widely used system for ranking tornado intensity. Tornadoes fall into six levels of intensity, with each assigned a particular EF-value ranging from 0 to 5. Fujita values are determined by trained observers who assess a tornado's impact on any of 28 categories of natural objects or built structures (softwood trees, service station canopies, motels, small barns, single-wide mobile homes, and so on) called damage indicators. The observers then assign a numerical value to represent the degree of damage to each damage indicator. A certain minimum wind gust speed lasting 3 seconds or longer is then assumed to create any particular degree of damage to a damage indicator, and this is translated to an EF value. In the United States, the 69 of tornadoes fall into the weak category, which includes EF-0 and EF-1.
