T-9-Q8.
A sudden increase in the production of elephant ivory artifacts on the Mediterranean coast of North Africa occurred in the tenth century. Historians explain this increase as the result of an area opening up as a new source of ivory and argue on this basis that the important medieval trade between North Africa and East Africa began at this period.
Each of the following, if true, provides some support for the historians’ account described above EXCEPT?
A. In East Africa gold coins from Mediterranean North Africa have been found at a tenth-century but at no earlier sites.
B. The many surviving letters of pre-tenth-century North African merchants include no mention of business transactions involving East Africa.
C. Excavations in East Africa reveal a tenth-century change in architectural style to reflect North African patterns.
D. Documents from Mediterranean Europe and North Africa that date back earlier than the tenth century show knowledge of East African animals.
E. East African carvings in a style characteristic of the tenth century depict seagoing vessels very different from those used by local sailors but of a type common in the Mediterranean.

2. GWD-27-Q2:
Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches. Unfortunately, electronic switches that are this small cannot withstand intense radiation. Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage. The switches will, however, be slower than electronic switches and the chip will contain only 12,000 switches.
For there to be a market for Micro-Mechanics’ chip as a result of the apparent advantage described above, each of the following would have to be true EXCEPT:
A. There will be applications in which the speed attainable by an electronic switch is not essential.
B. Switches used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than the switches on Micro-Mechanics’ chip will be.
C. There will be applications for computer chips in environments where the chips may have to survive intense radiation.
D. Some devices in which computer chips will be used will have other components that will be able to function during or after exposure to radiation.
E. Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.
电子计算机chips由极小的硅片组成包含了数百万的electronic switches.不幸的是，electronic switches.很小不能承受强辐射。Micro-Mechanics计划生产一种chip，因为它只使用微小的electronic switches因此可以经受辐射。但是这种 switches比普通的electronic switches要慢，而且这个chip只包含12000个switches.------- A答案：速度不重要，那么普通的优势就被削弱了。B答案：如果同样是12000S的传统芯片，和MM在抵御辐射上比较，如果较弱，则MM就有相当的优势；C答案: 如果电脑的工作环境一都是有辐射的，那么普通的chip完全被淘汰；D答案：chip所在的设备还有其他组成那是要在辐射下可以工作的，意思也是要暴露在辐射下。那么普通的chip也没有优势。只有E答案：如果给普通的chip装上防辐射的装置，那么MM的chip就没有优势了
