Question 5 Wind farms, which generate electricity using arrays of thousands of wind-powered turbines, require vast expanses of open land. County X and County Y have similar terrain, but the population density of County X is significantly higher than that of County Y. Therefore, a wind farm proposed for one of the two counties should be built in County Y rather than in County X. Which of the following, if true, most seriously weakens the planner's argument? - County X and County Y are adjacent to each other, and both are located in the windiest area of the state. - The total population of County Y is substantially greater than that of County X. - Some of the electricity generated by wind farms in County Y would be purchased by users outside the county. - Wind farms require more land per unit of electricity generated than does any other type of electrical-generation facility. - Nearly all of County X's population is concentrated in a small part of the county, while County Y's population is spread evenly throughout the county.

Question 6 Facts: The graph refers to a plane's flight from one location to another. The vertical axis represents the distance, in kilometers, between the plane and its destination. The horizontal axis represents the time, t minutes, since takeoff. Of all of the 20-minute intervals beginning and ending at times labeled on the graph, the interval in which the plane traveled farthest toward its destination was the interval from: ○ from t=20 to t=40 ○ from t=60 to at t=80 ○ from t=180 to t=200 ○ from t=240 to at t=260
