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 style=\"color:#cecece\">\nAnswers to the questions: <strong>B<\/strong>, <strong>E<\/strong><br \/>\nFor explanations please see these threads: <a href=\"https:\/\/gmatclub.com\/forum\/m07-70722.html\">math<\/a> and <a href=\"https:\/\/gmatclub.com\/forum\/cr-need-help-69528.html\">verbal<\/a>\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","protected":false},"excerpt":{"rendered":"<p>Math (DS) If , is an integer? 1. is an integer. 2.
