According to this magazine piece excerpted in "To Fly," what would be the main effect of building a space station?

"In the hands of the West, a space station, permanently established beyond the atmosphere, would be the greatest hope for peace the world has ever known. No nation could undertake preparations for war without the certain knowledge that it was being observed by the ever-watching eyes aboard the "sentinel in space." It would be the end of the Iron Curtains wherever they might be."

• It would watch for the establishment of new Iron Curtains.

• It would put space firmly in the control of Western powers.

• It would persuade people around the world to work for peace.

• It would ensure that no country could make plans for war unseen.

According to this passage from "To Fly," what is one way in which the Wright brothers' flight differed from earlier flights?

"Wilbur and Orville Wright were the first to fly a heavier-than-air, engine powered vehicle that carried a human being--Orville, in this case--and that did not land at a lower elevation than its takeoff point. Previously, people had flown in balloon gondolas and in gliders and had executed controlled descents from the sides of cliffs, but none of those efforts would have made a bird jealous.

• The flight carried more people.

• The flight did not land downhill

• The flight did not need an engine.

• The flight was entirely man-made.
