Hester and the other interns read that a primary science objective of the Apollo missions was to bring back rocks from a variety of places on the Moon's surface. Between 1969 and 1972, six Apollo missions brought back 382 kg (842 lb) of Moon rock. Partial results of these rocks are listed in Table 3 and Table 4. "Right," said Hester. "Each of the four hypotheses made specific predictions of the composition of Moon rocks. The next stage would be to compare each prediction with the real composition of Moon rocks and see which hypothesis was correct." "We have to be careful here," said the archivist. "As scientists we are never able to think of every possible hypothesis. It might be that none of the four hypotheses are correct."

11. Do these results support any of the four Moon formation hypotheses? Which? 12. Can you come to a definite conclusion cosmerning the Moon's origin?
