However, since many patients stop taking those drugs within three days, reinfection is common in cases where those drugs are prescribed. A new antibiotic requires only a three-day course of treatment. Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.<\/p>\n<p>Which of the following, if true, most strengthens the argument?<\/p>\n<p>(A) Some of the people who are allergic to penicillin are likely to be allergic to the new antibiotic.<br \/>\n(B) A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.<br \/>\n(C) The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep.<br \/>\n(D) Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections.<br \/>\n(E) Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days.<\/p>\n<div>\n<a href=\"https:\/\/gmatclub.com\/forum\/cr-need-help-69528.html\">Question Discussion &amp; Explanation<\/a><br \/>\n<strong>Correct Answer<\/strong> <span style=\"background-color:#fff;color:#fff\">- E -<\/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) If , is an integer? 1. is an integer. 2.
