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<div>\n<a href=\"https:\/\/gmatclub.com\/forum\/the-axis-of-earth-s-daily-rotation-is-tilted-with-respect-to-79385.html\">Question Discussion &amp; Explanation<\/a><br \/>\n<strong>Correct Answer<\/strong> <span style=\"background-color:#fff;color:#fff\">- B -<\/span> (click and drag your mouse to see the answer)\n<\/div>\n<p><\/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:\/\/click.linksynergy.com\/fs-bin\/stat?id=PJTlq5NYqfE&offerid=146261&type=3&subid=blog&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<p><a href=\"https:\/\/gmatclub.com\/blog\/category\/blog\/gmat-tests\/\"><strong>Browse all GMAT Questions of the Day<\/strong><\/a><\/p>\n<p><strong>Subscribe to GMAT Question of the Day:<\/strong> <a href=\"https:\/\/feedburner.google.com\/fb\/a\/mailverify?uri=GMAT-Question-of-the-day&amp;loc=en_US\">E-mail<\/a> | <a href=\"https:\/\/feeds.feedburner.com\/GMAT-Question-of-the-day\">RSS<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Math (PS) Robert can eat a 20 kg. bag of potatoes in 10 days.
