5. The museum's night security guard-maintains that the thieves who stole the portrait did not enter the museum at any point at or above ground level. Therefore, the thieves must have gained access to the museum from below ground level.

The flawed pattern of reasoning in the argument above is most similar to that in which one of the following?

(A) The rules stipulate the participants in the contest be judged on both form and accuracy. The eventual winner was judged highest in neither category , so there must be a third criterion that judges were free to invoke.
(B) The store's competitors claim that the store in selling off the shirts at those prices, neither made any profit nor broke even. Consequently, the store's customers must have been able to buy shirts there at less than the store's cost.
(C) If the census is to be believed, the percentage of men who are married is higher than the percentage of women who are married. Thus, the census must show a higher number of men than of women overall.
(D) The product label establishes that this insecticide is safe for both humans and pet. Therefore, the insecticide must also be safe for such wild mammals as deer and rabbits.
(E) As had generally been expected, not all questionnaires were sent in by the official deadline. It follows that plans must have been made for the processing of questionnaires received late.

答案B，不过我没看出有什么The flawed pattern of reasoning，好像逻辑没问题呀？
请大家指教。

12. By dating fossils of pollen and beetles, which returned after an Ice Age glacier left an area, it is possible to establish an approximate date when a warmer climate developed. In one glacial area, it appears from the insect record that a warm climate developed immediately after the melting of the glacier. From the pollen record, however, it appears that the warm climate did not develop until long after the glacier disappeared.

Each one of the following, if true, helps to explain the apparent discrepancy EXCEPT:

(A) Cold-weather beetle fossils can be mistaken for those of beetles that live in warm climates.
(B) Warm-weather plants cannot establish themselves as quickly as can beetles in a new environment.
(C) Beetles can survive in a relatively barren postglacial area by scavenging.
(D) Since planes spread unevenly in a new climate, researchers can mistake gaps in the pollen record as evidence of no new overall growth.
(E) Beetles are among the oldest insect species and are much older then many warm-weather plants.

答案E,不明白，C维和部队？请指教。

1.在作文argument中，有既得利益的驳斥法。与本题类似，结论都依赖于利害关系人的claim,故flawed.

2. Answer C means that beatles lived longer than plants after the glacier disappeared(postglacial ), and there was a relative shorter period from  extinction of cool beatls to thriving of warm ones than what happened to different plants.

錯誤二分法,

A. 為什麼不對？  如果是要規定參加比賽的人的規定, 這規定必定被評判在於類型以及準確度, 最後的贏家都沒有在這兩項取得最高分, 所以我們知道有第三項評判準則的存在。

這裡的因果關係是錯誤的去假設了贏家的與否跟分數的高低有關。 但是跟我們的錯誤二分法不同。

B. 錯誤二分法無誤。

12.

Spot the question type: Solve the discrepancy  ( Except )

From the insects record ---> Warm climate developed immediately after the melting or the glaciers

From the pollen record ---> Warm climate did develop ---> " long after " the glacier disappeared.

Ok, so our discrepancy lies in the times differences of the glacier vanish.

A. Attack one of the premise by indicating that fossil is not accurate.

B. and that's why it might be possible that the timelines are different as shown from both fossils

C. so, Plant has to wait until the glaciers truly vanish could plan be able to grow; however, it is not the case of the bug. they can survive in the poor environment.

D. Just as A, not a reliable evidence of the fossil

E. Think in this way

1. many does not mean all

2. Being oldest species does not mean both of the plants and beetle " can not " return together after an Ice Age glacier.

So, not solve the discrepancy at all
