关于L病毒的原题
Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice. However, certain other species on which the larvae feed do not harbor the bacterium. Therefore, if the population of these other species were increased, the number of ticks acquiring the bacterium and hence the number of people contracting Lyme disease-would likely decline.

Which of the following, if true, most strengthens the argument?
A.Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans.
B.There are no known cases of a human's contracting Lyme disease through contact with white-footed mice.
C.A deer tick feeds only once while in the larval stage.
D.A single host animal can be the source of bacteria for many tick larvae.
E.None of the other species on which deer tick larvae feed harbor other bacteria that ticks transmit to humans.

关于玛雅人定居的考古：OG13-119 (OG12-120)．
题目应该是这个，但是题型应该不一样。在熟悉题干基础上理解吧。The earliest Mayan pottery found at Colha, in Belize, is about 3,000 years old. Recently, however,4,500-year-old stone agricultural implements were unearthed at Colha. These implements resemble Mayan stone implements of a much later period, also found at Colha. Moreover, the implements' designs are strikingly different from the designs of stone implements produced by other cultures known to have inhabited the area in prehistoric times. Therefore, there were surely Mayan settlements in Colha 4,500 years ago.
Which of the following, if true, most seriously weakens
the argument?
(A)Ceramic ware is not known to have been used by the Mayan people to make agricultural implements.
(B)Carbon-dating of corn pollen in Colha indicates that agriculture began there around 4,500 years ago.
(C)Archaeological evidence indicates that some of the oldest stone implements found at Colha were used to cut away vegetation after controlled burning of trees to open areas of swampland for cultivation.
(D)Successor cultures at a given site often adopt the style of agricultural implements used by earlier inhabitants of the same site.
(E)Many religious and social institutions of the Mayan people who inhabited Colha 3,000 years ago relied on a highly developed system of agricultural symbols.
这个题答案是D，但是JJ中的题应该不是削弱。
