Scientist: In an experiment, dogs had access to a handle they could pull to release food into a nearby enclosure that contained a familiar dog and nothing else, contained an unfamiliar dog and nothing else, or was empty. The dogs typically released more food to the familiar dog than to the unfamiliar dog. This suggests that dogs are more motivated to help other dogs they know than to help unfamiliar dogs.
The scientist's argument would be most strengthened if it were true that, in the experiment, the dogs with access to the handle tended to release more food when
the behavior was being encouraged by a familiar person than when it was being encouraged by an unfamiliar person
the enclosure was empty than when it contained an unfamiliar dog
An unfamiliar dog in the enclosure was displaying hostility toward them than when an unfamiliar dog in the enclosure appeared friendly
a dog in the enclosure appeared uninterested in food already released into the enclosure than when it appeared interested in that food
a familiar dog was in the enclosure than when a familiar dog was visible but the enclosure was empty
E选项要展开的联想也太尼玛多了吧。。。
E 选项说的是狗狗相比那些虽然熟悉，但不在围墙内的狗狗，更愿意帮助那些熟悉但是在围墙内的狗狗
B the enclosure was empty than when it contained an unfamiliar dog （无关，果是讲familiar vs unfamiliar，跟empty vs unfamiliar无关）
E a familiar dog was in the enclosure than when a familiar dog was visible but the enclosure was empty （加强，认识的狗在围墙里（给得到）vs认识的狗看得见却不在围墙里（给不到）的时候，给前者更多，说明了狗狗is motivated帮认识的狗）
就是前者是意识到 把食物给柜子里的狗狗是能够帮助到的情况，后者是虽然看到了熟悉的狗，但是帮不到的情况
P：狗“给认识的狗的食物”多过“给不认识的狗的食物”（果）
C：相比于帮助不认识的狗，狗对于帮助认识的狗更有动力（因）
果因推理，他因or否定因果关系，选项必有果
• Athe behavior was being encouraged by a familiar person than when it was being encouraged by an unfamiliar person （削弱，这里提出了他因：狗是被认识的人鼓励这样做的）
• Bthe enclosure was empty than when it contained an unfamiliar dog （无关，果是讲familiar vs unfamiliar，跟empty vs unfamiliar无关）
• CAn unfamiliar dog in the enclosure was displaying hostility toward them than when an unfamiliar dog in the enclosure appeared friendly （无关，果是讲familiar vs unfamiliar，跟hostile unfamiliar vs friendly unfamiliar无关）
• Da dog in the enclosure appeared uninterested in food already released into the enclosure than when it appeared interested in that food （无关，果是讲familiar vs unfamiliar，跟里面的狗有或没有兴趣无关）
• Ea familiar dog was in the enclosure than when a familiar dog was visible but the enclosure was empty （加强，认识的狗在围墙里（给得到）vs认识的狗看得见却不在围墙里（给不到）的时候，给前者更多，说明了狗狗is motivated帮认识的狗）
E 乍一看没反应过来，其实在讲狗愿意帮助。做题目的时候过分强调familar 和 unfamiliar狗之间的比较，忽略了help
填空題，等於從上述往下推論要一致:狗會幫助狗朋友--->達到加強效果
A---> a familiar person/ an unfamiliar person 引入外來因子，如果成立，反而削弱原先推論
B--->反向削弱，沒狗朋友卻留更多，代表一開始認為狗會幫助朋友的立論有誤
C---> hostilit引入外來因子，如果成立，反而削弱原先推論
D--->appeared uninterested in food引入外來因子，如果成立，反而削弱原先推論
E--->合理，狗朋友在一起就幫助；沒在一起就無所謂
又秒选A，竟然把人看成了狗…… “他好像条狗啊！”
E的狗还挺聪明
天，看到你这条评论我才意识到不是dog是person

其实在讲狗愿意帮助。做题目的时候过分强调familar 和 unfamiliar狗之间的比较，忽略了help
the dog may be, in fact, just more likely to provide more food, or press the handle more, when this dog merely sees a familiar dog, whether that familiar dog is in an enclosure or not. Well, this would then mean that the dog doesn't necessarily care about helping. It just puts more food into an enclosure when it sees a familiar dog that is in that enclosure or anywhere visible (not necessarily in that enclosure)
两个point：help，熟悉的狗；A只讲到了熟悉，E既讲到了熟悉又讲到了help，证明力最强。
C，对面的狗展现出敌意时还给了它更多的食物，说明敌意越多食物越多，属于削弱。
狗给熟悉的狗更多food---狗更愿意帮助熟悉的狗
A 他因，被熟悉的人影响削弱原文
B 无关比较
C 有无敌意，他因削弱
D 狗是否有兴趣，他因削弱
E 乍一看没反应过来，其实在讲狗愿意帮助。做题目的时候过分强调familar 和 unfamiliar狗之间的比较，忽略了help
A. who encouraged the behavior is not relevant
E. the release of food into the empty enclosure would not help the visible dog and thus the dog with handle will release lesser amount of food.
E 强调help
