ASSUMPTION GWD-1-Q40: Until Now, only injectable vaccines against influenza have been available. Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated. A new influenza vaccine, administered painlessly in a nasal spray, is effective for children. However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray. Which of the following is an assumption on which the argument depends? Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.

Adults do not contract influenza primarily from children who have influenza.排除削弱。原来说给小孩注射这种新疫苗对公众健康不会有多大好处，现在就说有好处来削弱。或者理解成GAP。children seldom develop serious complications from influenza = no significant public health benefit弥补这个GAP。这里有一个分类小孩和大人。结论只考虑了小孩，从大人入手。 The nasal spray vaccine is mot effective when administered to adults.[D] GWD-2-Question 11: Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservatives. However, since there are several wine makers who add sulfites to none of the wines they produce, people who would like to drink wine but are allergic to sulfites can drink wines produced by these wine makers without risking an allergic reaction to sulfites. 喝没有添加S的酒就不会对S过敏。没有添加不等于没有 A被加进去某样东西，人们对加进去的这样东西又反映；要消除人们的反应，也要看A本身有没有这样东西。 Which of the following is an assumption on which the argument depends? These wine makers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine.反前提 Not all forms of sulfite are equally likely to produce the
