Answer

D. 4-1-5-2-3-6

Solution

The correct order is 4-1-5-2-3-6. Each sentence picks up an idea from the one before it: A wind turbine converts the energy of moving air into electricity. The wind turns its large blades, which are connected to a shaft. This rotating shaft drives a generator housed at the top of the tower. Because wind speed increases with height, turbines are mounted on tall towers. The Bangui wind farm in Ilocos Norte was among the first large installations of this kind in Southeast Asia. Its row of turbines along the coast has since become a tourist attraction as well as a power source. Each wrong choice swaps just one pair of neighboring sentences, which breaks one of these links.
