Everyfall Croton's jays migrate south. Thejays always join flocks of migrating crookbeaks with which they share the samesummer and winter territories. If a jaybecomes separated from the crookbeaks it is accompanying, it wanders until itcomes across another flock of crookbeaks. Clearly, therefore, Croton's jays lack the navigational ability to findtheir way south on their own.
Whichof the following, if true, most strengthens the argument above?
A.Croton's jays lay their eggs in the nests of crookbeaks, which breed uponcompleting their southern migration.
B.The three species most closely related to crookbeaks do not migrate at all.
C.In the spring, Croton's jays migrate north in the company of Tattersallwarblers.
D.Species other than Croton's jays occasionally accompany flocks of migratingcrookbeaks.
E.In the spring, crookbeaks migrate north before Croton's jays do.
C咋就加强了呢？。。。

Editor: Articles in Gardening Magazine often spur salesof the plants they describe, particularly among people new to gardening. Accordingly, we will no longer publisharticles or accept advertisements praising the beauty of rare wildflowers. Most such plants sold to gardeners have beendifficult to propagate under cultivation, so plant sellers often collect themin the wild. Our new policy is part ofour efforts to halt this yearly plundering of our native plant populations.
Whichof the following, if true, casts the most doubt on the wisdom of the magazine'snew policy as a way of pursuing the intended effect?
A.When people new to gardening buy plants, they often fail to take adequate careof the plants that they buy and become discouraged from buying those varieties again.
B.Plant sellers who sell rare wildflowers have no reasonably inexpensivealternative way to offer their wares directly to new gardeners.
C.The demand for rare wildflowers rarely exceeds the number of such plants thatcan be collected in the wild by plant sellers.
D.The propagation of rare wildflowers often depends on the plants' interactionwith other organisms in their environment, such as plants that create suitablesoil conditions or insects and birds that disperse seeds.
E.Revenues from sales of plants collected in the wild are supporting thediscovery of new low-cost techniques enabling rare wild flowers to be readily propagated in nurseries.

A为何就不对呢

Followingseveral years of declining advertising sales, the Greenville Times reorganizedits advertising sales force two years ago. Before the reorganization, the sales force was organized geographically,with some sales representatives concentrating on city-center businesses andothers concentrating on different outlying regions. The reorganization attempted to increase thesales representatives’ knowledge of clients’ businesses by having each salesrepresentative deal with only one type of industry or of retailing. After the reorganization, advertising salesincreased.
Inassessing whether the improvement in advertising sales can properly beattributed to the reorganization, it would be helpful to find out each of thefollowing EXCEPT:
A.Two years ago, what proportion of the Greenville Times’s total revenue wasgenerated by advertising sales?
B.Has the circulation of the Greenville Times increased substantially in the lasttwo years?
C.Has there been a substantial turnover in personnel in the advertising salesforce over the last two years?
D.Before the reorganization, had sales representatives found it difficult to keepup with relevant developments in all the types of businesses to which they wereassigned?
E.Has the economy in Greenville and the surrounding regions been growing rapidlyover the last two years?

E咋不对了，A咋对了。。。

没事，这几题目都错过，帮你分析下，其中最后97，答案应该是D，

85：类比加强:本质一样，都是不认识路
92：A选项是无关选项，题目问阻止去野外collect wild plant的计划能否成功，与买花人能否照看好花朵没关系
93: A没关系。举个例子，2年前销售总的为A，广告占50%，其他50%，2年后总的销售还为A，广告占60%，其他40%。这里有好几种可能性，其中一种因为公司削减了其它部门，或者其它部门被卖掉了一部分，从而广告占比重上升，这样与广告部门本身没啥关系
E是有关系的，因为如果周围经济非常好，引起总体经济发展迅速，这样就与广告部门本身重组关系没有了

。。我晕了，97题我选的是D，可能错太多，眼都花了。谢谢你
可是我还是觉得那3题有点想不通。
85：类比加强。。我好像有点知道那个意思了，但是还是有点晕
92：A选项我觉得如果买花人看不好花，不会重复购买，卖花的sale就会直接下降，就会消弱去采野花的行为啊。。
93：E项，整个地区的经济增长，这项我觉得也无关啊。
麻烦再给我说说好么。。。谢谢谢谢！恭喜发财！
