Each passage below is followed by a question. Read the passage carefully and answer the question that follows.One theory of the Moon's origin is that the Earth, early in its development, was a rapidly rotating body of molten rock in which most of the iron had settled to the core; some of this fluid was cast off from the surface of the spinning mass and later solidified to form the Moon.Which of the following conclusions can best be supported by the theory above of the Moon's origin, if that theory is correct?
