The study was conducted using pairs of photographs of 200 women and volunteer viewers who chose the photograph in which they thought the woman appeared more attractive. Researchers found that 67% of the time viewers chose the photo taken when the woman was ovulating.<\/p>\n<p>The methodology of the study above is flawed for which of the following reasons?<\/p>\n<p>(A) The study fails to specify what is meant by the word attractive, leaving it up to the opinion of the individual viewer.<br \/>\n(B) Because all the viewers were male, the results of the study were skewed by individual responses to attractive women.<br \/>\n(C) The study fails to account for the psychological complexity of sexual desire in women<br \/>\n(D) The study assumes that women will dress more attractively when they have greater sexual desire.<br \/>\n(E) Most women do not know when they are ovulating, and so would not dress more attractively on that day.<\/p>\n<div>\n<a href=\"https:\/\/gmatclub.com\/forum\/a-study-attempting-to-link-fertility-with-increased-sexual-78331.html\">Question Discussion &amp; Explanation<\/a><br \/>\n<strong>Correct Answer<\/strong> <span style=\"background-color:#fff;color:#fff\">- A -<\/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:\/\/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=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 (DS) Set consists of a certain number of even integers divisible by 3.
