I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "A local industry manufacturing fibre from New Zealand flax was successfully reestablished in 1907 and generated considerable income during the First World War. Ascension Island was made a dependency of Saint Helena in 1922, and Tristan da Cunha followed in 1938. During the Second World War, the United States built Wideawake airport on Ascension in 1942, but no military use was made of Saint Helena."? 

Which conflict was not occurring when Wideawake airport was being erected, the First World War or the Second World War?
