tpo15 Mass extinction
Paragraph 2: The fossil record shows at least five mass extinctions in which many families of marine organisms died out. The rates of extinction happening today are as great as the rates during these mass extinctions. Many scientists have therefore concluded that a sixth great mass extinction is currently in progress.
2. According to paragraph 2, scientists base their belief that a mass extinction is going on at present on which of the following?
○The speed with which mass extinctions are happening today is similar to the speed of past extinctions.
○The number of species that have died out since the last extinction event is extremely large.
○Mass extinctions occur with regularity and it is time for another one.
○Fossil records of many marine species have disappeared.
这题我觉得c也对啊?
Tpo14
Paragraph 4: Nomadism also subjects pastoralist communities to strict rules of portability. If you are constantly on the move, you cannot afford to accumulate large material surpluses. Such rules limit variations in accumulated material goods between pastoralist households (though they may also encourage a taste for portable goods of high value such as silks or jewelry). So, by and large, nomadism implies a high degree of self-sufficiency and inhibits the appearance of an extensive division of labor. Inequalities of wealth and rank certainly exist, and have probably existed in most pastoralist societies, but except in periods of military conquest, they are normally too slight to generate the stable, hereditary hierarchies that are usually implied by the use of the term class. Inequalities of gender have also existed in pastoralist societies, but they seem to have been softened by the absence of steep hierarchies of wealth in most communities, and also by the requirement that women acquire most of the skills of men, including, often, their military skills.
10. According to paragraph 4, all of the following are true of social inequality in pastoralist societies EXCEPT:
○It exists and has existed to some degree in most pastoral societies.
○It is most marked during periods of military conquest.
○It is expressed in the form of a rigid hierarchy based largely on heredity.
○It is usually too insignificant to be discussed in terms of class differences.
为啥不选B啊?文中不是说“but except in periods of military conquest,。。”吗?

看清楚那句话的they代表什么
如果你要从语法上分析必须是复数,只有inequalities,所以 except这句话表达的意思就是 during military conquest, the inequalities are to the most extensive stance.
