In 1960’s studies of rats, scientists found that crowding increases the number of attacks among the animals significantly. But in recent experiments in which rhesus monkeys were placed in crowded conditions, although there was an increase in instances of “coping” behavior-such as submissive gestures and avoidance of dominant individuals-attacks did not become any more frequent. Therefore it is not likely that, for any species of monkey, crowding increases aggression as significantly as was seen in rats.
Which or the following, if true, most strengthens the argument?
A. All the observed forms of coping behavior can be found among rhesus monkeys living in uncrowded conditions.
B. In the studies of rats, nondominant individuals were found to increasingly avoid dominant individuals when the animals were in crowded conditions.
C. Rhesus monkeys respond with aggression to a wider range of stimuli than any other monkeys do.
D. Some individual monkeys in the experiment were involved in significantly more attacks than the other monkeys were.
E. Some of the coping behavior displayed by rhesus monkeys is similar to behavior rhesus monkeys use to bring to an end an attack that has begun.

由于手机越来越多,很少人现在使用飞机上的电话,但因为电话回护费由电话公司承担,航空公司从通话费中抽取部分收入,因此飞机上的电话还是有利可图,问假设?

夏威夷发展的测定
a、最新研究证明夏威夷社会政治的发展比预想快。口述历史讲述17世纪初有个大牛人P统一了夏威夷,但无法证明,因为相关证据无法用C14测定年代。科学家用了新方法,证明大量用于分配产品的寺庙建于17世纪初,从而证明了口述历史中17世纪初的大变革。
b、第一段:某个文明或者宗教有个庙,可能比传统学者完成的时间要早。但是又没有确实的理论来支持。
第二段:新的科技或者是证据(这一点大家认真读吧)利用同位素测试装饰这个塔的某个海生植物。测出其丰 收的时间等等。(就是说明了这个塔修时间和原来想的不一样)。由于这个台是当地多余(surplus)物品的聚集和交换地,有重要的作用。因此都出这社会文明结构(这个复合词不认识)may serve one generation.
burdle saling strategy(捆绑销售)
a、burdle saling strategy, introduce two types, one is xx hurdling, for example, credit card company, the other is loyalty burdling,解释了下,文章容易,问题较难,由主题题,答案无法确定。
b、企业销售的BUNDLING策略可以降低推广难度,减少推广时间,策略有两种,一种是打包销售,顾客对其中一种感兴趣就会买下所有产品,一种是忠诚策略,是为了防治顾客购买竞争对手产品。无论那种策略,都不会影响企业单独销售的产品的销量
美国企业竞争力下降
1980年代中期,美国企业在世界市场的竞争力开始下降。这是为什么丫?大家开始研究。有的经济学家说,因为美国企业的资本成本高于其他国家。有的经济学家说,因为在60-80年代美国企业缺乏对长期资本的投入,比如说研发或者固定资产。可是既然这些因素对企业普遍有影响,但是各行业的表现却不尽相同呢?比如说钢铁行业和航空业,都是属于需要大量资本投入的企业。钢铁行业80年代大量亏损,而航空行业却蒸蒸日上。哦问题可能不在长期投资吧。问题在于企业内部投资,比如说人力啦,组织结构啦,这些才是影响企业表现的因素。
别的没记住
