yawning传递要睡觉的讯息。在一个群体中，如果没有个体打哈欠，那么大家都认为没到要睡觉的时候，而只有睡觉个体才能survive，问的好像是assumption只记得两个个选项一个说的好像是睡觉前比睡觉后打哈欠多（废话啊可能误读当时已经脑残）还有一个说是基因决定大部分动物是群居性的考古：v1

Yawning

of

animal是signal族群中其他成員給予自己休息，不打呵欠的成員會一直被其他成員弄醒，這種行為在group裡比較明顯，而且提到這個Yawning與存活率有關@@我忘了是問support、weaken還是assumption(好像是support)我記得我選的答案是有關睡覺時間長的動物比較不會打呵欠，睡眠時間短的打呵欠次數與間隔多，還有什麼before-yawning與after

yawning、indivisual與group的關係v2动物打哈气。说动物yawning是表示对同伴说要睡觉了，否则the

others

will

keepthem

awake.No

sleep,no

survive.问加强。我选的是A最长的那句，是说动物在睡醒后也会yawning，但是before

the

sleep，他们在community里面yawning的frequency更多。大仙：此题扑朔迷离，稍微有点靠谱的是考古的V2.真题震撼还原！亲爱的，再多看我一眼方案----目的再多看一眼目的In

meet

environmental

xxxx。问题是weaken类的。记得两个选项：一个是，纸张等废物在加湿之后会缩小因此能腾出空间另一个是，加水会产生废水，污染下水道blablablav2

landfill注水能加快垃圾decompose的速度，因此决定弄一个注水的设备，问削弱A注水设备很便宜B污水很可能会流进河流跟湖泊里C

paper和有些垃圾遇水体积会更容易压缩因此能使landfil少占地2.垃圾浸水分解考古：v1有一道垃圾场的题好像是新的，说垃圾场大部分的垃圾都是paper的，遇水会加速降解，政府为了减少landfill的space打算在垃圾场旁边建造一个水泵。问削弱：A有些垃圾遇湿会膨胀。B垃圾会产生有毒的水流流进河里(脏水深入河流湖泊地下水造成更大污染)C

cost增加之类的。【猜想逻辑链】-zkybq看目的，这题历史上有大牛选择B，但是明显目的是减少空间，所以与污染无关V2专家发现，往垃圾堆灌水会使垃圾堆体积变小，因为它吸收了。所以有人说建一个watersystem，这样的话可以使同样体积的landfill吸收更多的垃圾，既可以节省空间，又可以保护环境。问削弱。狗主选了这些吸收的water会进入river等系统。其它选项好像都还挺好排除的。V3垃圾吸收水分后decompose更快，所以可以建一个water

system保持landfill的地方wet这样垃圾更快分解可以减小landfill的区域，保护环境。问削弱。狗主选污染后的水可能流进lake,river.大仙：最爱的警醒大家的题目.看清楚结论不要自行YY真题震撼还原！11.小绵羊保暖原始：v1刚出生的lamb容易被冻死，有种毛毡（？）能够在冬天给lamb取暖减少冻死的，这个毛毡很便宜，但是如果给全农场的羊都搞这个毛毡农民就承担不了这个费用了，但是这个方案依然可行，因为C被冻死的小羊都是出生的时候体重低于一个值的

adult羊不容易被冻死考古：完成句子：说的是一种小羊刚生出来不抗寒，冬天经常会生病然后就死掉了，现在有一种衣物能帮助保持羊的体温，虽然造价不贵，但农民不能给所有小羊一人买一个。但是，明年开始羊的死亡率会大大降低，因为

飞机分配座位的测略，航空公司一开始实行

section登机，就是比如座位号靠前的先登机，然后中间然后后面，发现这样很慢，因为放行李的人会挡到后面人登机。后来航空公司实行按照座位的style登机，就是靠窗户的先登机，然后座中间的，最后坐过道的，问支持后面这种策略的选项

oil对好车有用，但是对普通车没用，也就是说普通车没有必要用p

oil。好车占10%，但是实际发现premium

oil的使用量占了15%，问一下哪项最能说明普通车主用

premium

oil是浪费钱。我选了premium

oil的价格与最便宜（lease

expensive）的普通油高出25%（咨询了H，他是这么解释的题目问哪项最能说明普通汽车用号汽油是浪费钱，我个人感觉是，看了几个选项，最后一个比较像答案。因为好汽油的费用比最便宜的普通汽油高出25%，也就是说普通汽车最多可以节省25%的费用。不知道我这样的理解对不
