51. 風能發電和火電發電

　　V2 from davidwu27深刻记得某一题说风能发电厂比火电厂更占用土地面积破坏植被。我选的是，火电所需的煤是来自大大破坏植被的煤矿厂的····

　　52.拍賣畫

　　V1 from vvvjy8868 700 .貌似是说拍卖会上，历史超过100年的卖了1.45(记不清了)million， 反正很贵，但是当代画家的画都拍不了那么高的价格，解释题，我选了被转卖过多次的作品比没转卖过的作品卖的贵

　　v2 from tree830224艺术品拍卖：去年拍卖会上，艺术家的作品最终成交价都很高，可是相关人员还是对艺术的前景表示担忧，问evaluate。(选项有：Few serious bidders participate in the auction enable no competitors , thus increasing the price; 担心拍卖会的高价，会使得艺术界逐渐商业化;)

　　53 犯罪率真的低了么

　　vvvjy8868 700 说是为了降低某个地方的犯罪率，在那装了照相机还是什么的，结果发现，那里报案说自己被抢的人少了比别的地方少了，但是camera显示哪个地方 的mug没有减少，问解释，我学的好像是什么保险公司有个什么政策，所以被抢的人不愿意去报案。。

　　54 傳染病

　　from zy900303就是大人很容易感染某个病，但是小孩子们却不打疫苗，因为痛，最近发明了一个新的疫苗，不疼。可是小孩子还是不去打。问assumption?

　　答案应该是小孩不会把那个病传染给大人。

　　考古和变体题

　　From 奔跑的悟空GWD-TN-1GWD1-Q40:

　　Until mow, 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 fective for children.However, since children seldom develop serious complications from influenza, no significant public health benit would result from widespread vaccination of children using the nasal spray.

　　Which of the following is an assumption on which the argument depends?

　　A.Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.

　　B.The new vaccine uses the same mechanism to ward off influenza as jnjectable vaccines do.

　　C.The injectable vaccine is affordable for all adults.

　　D.Adults do not contract influenza primarily from children who have influenza.

　　E.The nasal spray vaccine is most fective when administered to adults.

　　一种新型的vaccine,使用方法不是注射而是喷洒，因此适合儿童使用，但是儿童不会因为这个influenza产生严重的并发症，因此认为在儿童中广泛使用vaccine不会产生significant public benits.-------前提：如果这个infuenza可以由儿童传染给大人，那么儿童使用这个vaccine就是断绝这个传染途径，从而有了public benits.

　　FROM clumsyorange PREP Until now, only injectable vaccines against influenza have been available. They have been used primarily by older adults, who are at risk for complications from influenza. A new vaccine administered in a nasal spray has proven fective in preventing influenza in children. Since children are significantly more likely than adults to contract and spread influenza, making the new vaccine widely available for children will greatly reduce the spread of influenza across the population.

　　Which of the following, if true, most strengthens the argument?

　　A. If a person receives both the injectable and the nasal-spray vaccine, the two vaccines do not interfere with each other.

　　B. The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.

　　C. Government subsidies have kept the injectable vaccine affordable for all older adults.

　　D. Of the older adults who contract influenza, relatively few contract it from children with influenza.

　　E. Many parents would be more inclined to have their children vaccine against influenza if the vaccination did not require an injection.

　　这题一开始还错选了D，其实人家D只把重心放在了older adults，很迷惑啊很迷惑。。。后来好好想了想才找到正确答案E。建议可以跟刚才楼上的考古一起对照看一看，呵呵~

　　55. 船沉沒的時間

　　tree830224一艘沉船，据船里面发现的coins推测，船是某个时期沉没的，然而，与此同时，还在这艘船旁找到J物。奇怪的是，J物时期比coins早，问解释(选项有：水手往往为了减少船的分量，而将船上货物扔进水里;J物与coins发现的地方相同;….);

　　56 船沉沒的原因

　　tree830224还有一道也是沉船，说的是，有人认为沉船的原因是地震;有人认为是因地震引起的暴风雨。。。但有人反驳说，不可能是上述原因，因为这些都会造成巨大的损坏，导致船因漏水而沉没。但该国并没有report该船的修理，也没有船长perceived such leak bore sank;问削弱。(选项有：船上的货物让leak变得不明显，直到那些货物因吸收水分变重而使船沉没;该国有采取足够的保护措施防暴风雨;暴风雨的危害对其他而言是巨大的，但不足以给该船造成明显的损坏….)

　　57花粉傳播

　　tree830224有些花是通过pollinator传播花粉繁殖，有些是self-pollinated。好像说，通过昆虫传播花粉的species数量大大减少，推论是因为pollinator infection, 问evaluate。(选项有： whether the number of self-pollinated species also decreased;….)

　　58. 護士和病人的比例

　　from Behind一家医院，原来护士和病人之比是1:6，后来医院提议要把比例提高到1:5，问weaken

　　v2 from silence05 760另一个 因为政府政策要提高护士对住院病人的比率 而当地的护士不足 需要从外地招聘护士 问削弱该措施

　　我选的是可以通过XXXX或者是减少让病人住院的诊断

　　v3 from laputahx护士病人1:5到1:6, 要多招护士了。 问weaken。我选医院可以减少病人留院时间什么的，这个也比较有把握，别的选项都很不靠谱。

　　v4 from flankfan (ID: 528948)狗狗58，护士和病人的比例。某个地方护士和病人原来的比例是1:6，新的立法规定要到1:5，所以推出别的地方的护士要被吸引过来，问weaken。我选的是别的地方的护士也不够用。(奶奶的，这题一开始哥竟然看成了护士和医生的比例，我ft~~~受了某篇阅读狗的影响。5555)

　　59. 少吃脂肪 降低心髒病發病率

　　V1 from rechardql760记得一道比较清楚的题: scientists have discovered that lower input of fat and higher intake of fibor can help reduce the risk of heart attack to the people with similar lifestyle. So it&aposs recommended that increasing fibor in diet and reduce fat in diet are each fective ways to reduce the possibility of heart attack.

　　问上述中有啥疏忽或者错误，其中一个选项大概是the recommendation overlooks the possibility that each of the two factors reinforce each other but only one of the two can hardly generate any expected result. 选这个

　　V2 from Hugsy 二战710 V34 Q50Tomato那道，有种物质可以减少心脏病的几率，但是加工后会使那种物质减少，但研究表明，少吃加工过的T就能达到目的，问解释：我选的是加工过的T更容易被吸收
