5.2北美

阅读 考了jazz music, market share, 和蝌蚪死活水那篇，有篇JJ上没有的，讲广告的，我大概回忆下，不是很记得清了

P1 有个研究吧说的是广告内容/形式的影响。举个牛肉例子，若是广告写75%lean和25%fat的话，就会吸引更对人，这个这种广告形式呢，positive占的 多，negative占的少，比较好。 但是又有研究表明了哈，其实不是这样的，negative占的多possitive占的少的反而效果可能会更好

P2 说明了这种广告好坏比例不同要根据customer的involvement，customer involve多的花，negative比例多positive比例少好点，但如果involve少的话，positive比例多negative比例少好点

逻辑

Prep上的原题，杂志决定不刊登关于野花的文章那个，不过问题变成了问support

1/x+1/y=1/z,   x用y和z表示

P是大于3的质数，问下面那个只有exactly one  factor 除了1和他本身之外

选项有2p,3p, 4p, p^2, p^3

一个index is proportional to the square of the unemployment rate, 现在unemployment rate increase10%, 问index增加了多少

感谢分享！逻辑应该是这道吧Editor: Articles in Gardening Magazine often spur sales of the plants they describe, particularly among people new to gardening. Accordingly, we will no longer publish articles or accept advertisements praising the beauty of rare wildflowers. Most such plants sold to gardeners have been difficult to propagate under cultivation, so plant sellers often collect them in the wild. Our new policy is part of our efforts to halt this yearly plundering of our native plant populations.
　　Which of the following, if true, casts the most doubt on the wisdom of the magazine's new policy as a way of pursuing the intended effect?
　　A. When people new to gardening buy plants, they often fail to take adequate care of the plants that they buy and become discouraged from buying those varieties again.
　　B. Plant sellers who sell rare wildflowers have no reasonably inexpensive alternative way to offer their wares directly to new gardeners.
　　C. The demand for rare wildflowers rarely exceeds the number of such plants that can be collected in the wild by plant sellers.
　　D. The propagation of rare wildflowers often depends on the plants' interaction with other organisms in their environment, such as plants that create suitable soil conditions or insects and birds that disperse seeds.
　　E. Revenues from sales of plants collected in the wild are supporting the discovery of new low-cost techniques enabling rare wildflowers to be readily propagated in nurseries.

2, x^2y<0
条件2怎么会小于0呢。。
