That angle can be kept fairly stable only by the gravitational influence of Earth\u2019s large, nearby Moon. Without such a stable and moderate axis tilt, a planet\u2019s climate is too extreme and unstable to support life. Mars, for example, has only very small moons, tilts at wildly fluctuating angles, and cannot support life. <\/p>\n<p>If the statements above are true, which one of the following must also be true on the basis of them? <\/p>\n<p>(A) If Mars had a sufficiently large nearby moon, Mars would be able to support life.<br \/>\n(B) If Earth\u2019s Moon were to leave Earth\u2019s orbit, Earth\u2019s climate would be unable to support life.<br \/>\n(C) Any planet with a stable, moderate axis tilt can support life.<br \/>\n(D) Gravitational influences other than moons have little or no effect on the magnitude of the tilt angle of either Earth\u2019s or Mars\u2019s axis.<br \/>\n(E) No planet that has more than one moon can support life.<\/p>\n<p><a href=\"https:\/\/gmatclub.com\/forum\/earth-79385.html\">OA and Explanation<\/a><\/p>\n<p><strong>Like these questions?<\/strong> Get the GMAT Club question collection: <a href=\"https:\/\/gmatclub.com\/tests\/\">online at GMAT Club<\/a> OR <a href=\"https:\/\/www.amazon.com\/gp\/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2Fgp%2Fentity%2FGMAT-Club%2FB0048PPF3U%3Fie%3DUTF8%26ref_%3Dntt_athr_dp_pel_1&tag=gmatclub-20&linkCode=ur2&camp=1789&creative=390957\">on your Kindle<\/a> OR <a href=\"https:\/\/click.linksynergy.com\/fs-bin\/stat?id=PJTlq5NYqfE&offerid=146261&type=3&subid=0&tmpid=1826&RD_PARM1=http%253A%252F%252Fitunes.apple.com%252Fus%252Fapp%252Fgmat-toolkit%252Fid328345537%253Fmt%253D8%2526uo%253D6%2526partnerId%253D30\">on your iPhone\/iPad<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Math (PS) Robert can eat a 20 kg. bag of potatoes in 10 days.
