Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to eachof the following questions from (71) to (80)The Moon has been worshipped by primitive peoples and has inspired humans to createeverything from lunar calendars to love sonnets, but what do we really know about it? The most acceptedtheory about the origin of the Moon is that it was formed of the debris from a massive collision with theyoung Earth about 4.6 billion years ago. A huge body, perhaps the size of Mars, struck the Earth,throwing out an immense amount of debris that coalesced and cooled in orbit around the Earth. The development of Earth is inextricably linked to the moon; the Moon’s gravitational influenceupon the Earth is the primary cause of ocean tides. In fact, the Moon has more than twice the effect uponthe tides than does the Sun. The Moon makes one rotation and completes a revolution around the Earthevery 27 days, 7 hours, and 43 minutes. This synchronous rotation is caused by an uneven distribution ofmass in the Moon (essentially, it is heavier on one side than the other) and has allowed the Earth’s gravityto keep one side of the Moon permanently facing Earth. It is an average distance from Earth of 384,403km. The Moon has no atmosphere; without an atmosphere, the Moon has nothing to protect it frommeteorite impacts, and thus the surface of the Moon is covered with impact craters, both large and small.The Moon also has no active tectonic or volcanic activity, so the erosive effects of atmosphericweathering, tectonic shifts, and volcanic upheavals that tend to erase and reform the Earth’s surfacefeatures are not at work on the Moon. In fact, even tiny surface features such as the footprint left by anastronaut in the lunar soil are likely to last for millions of years, unless obliterated by a chance meteoritestrike. The surface gravity of the Moon is about one-sixth that of the Earth’s. Therefore, a man weighing82 kilograms on Earth would only weigh 14 kilograms on the Moon.The geographical features of the Earth most like that of the Moon are, in fact, places such as theHawaiian volcanic craters and the huge meteor crater in Arizona. The climate of the Moon is very unlikeeither Hawaii or Arizona, however; in fact the temperature on the Moon ranges between 123 degrees C. to–233 degrees C.
