60. One of the more reliable methods of determining regional climatic conditions in prehistoric periods is to examine plant pollen trapped in glacial ice during ancient times. By comparing such pollen samples with spores take from modern vegetation, scientists can figure out approximately what the weather was like at the time of pollen deposition. Furthermore, by submitting the prehistoric samples to radiocarbon dating techniques, we can also determine when certain climatic conditions were prevalent in that portion of the globe.

Which one of the following may be
                    inferred from the information in the passage?

(A) The earth has undergone several glacial periods.

(B)
                    Radiocarbon dating can be corroborated by glacial evidence.

(C) Similarities between prehistoric and contemporary climates do not exist.

(D) Pollen deposition is a fairly continuous process.

(E) Certain flora are reliably associated with particular climatic conditions.

答案是E，解释如下：

for INFERENCE questions, you should treat it the same way as ASSUMTION question. First, understand the conclusion, or the statement in this question. And find the REQUIRED condition in the choices. To test the answer, use “NOT” and put it back in the argument to see if conclusion still holds.

即是要将inference题当作assumption来做，进行反向推理；而

74. Governments have only one response to public criticism of socially necessary services: regulation of the activity of providing those services. But governments inevitably make the activity more expensive by regulating it, and that is particularly troublesome in these times of strained financial resources. However, since public criticism of childcare services has undermined all confidence in such services, and since such services are socially necessary, the government is certain to respond.

Which one of the following statements can be inferred from the passage?

(A) The quality of child-care will improve.

(B) The cost of providing child-care services will increase.

(C) The government will use funding to foster advances in child-care.

(D) If public criticism of policy is strongly voiced, the government is certain to respond.

(E) If child-care services are not regulated, the cost of providing childcare will not increase.
                

同样是inference，这里又是正向推理，当作conclusion来做 (我的第一感觉是选D，答案是B)。

我的理解是60题中，因为结论已经说明了：One of the more reliable methods of determining regional climatic conditions in prehistoric periods is to examine plant pollen trapped in glacial ice during ancient times. ，所以这里的inference要求我们根据结论推导premise;

而74题中，并没有结论，所有passage提到的内容都是premises，所以我们这里的inference要求我们推到结论：The cost of providing child-care services will increase。

不知道这样的理解对不对，疑惑中。。。
