Which of the following best illustrates the relation between reason and revelation?
［A］ They are simply identical.
［B］ Revelation guides reason.
［C］ They are occasionally contradictory.
［D］ Reason is used to perfect revelation.
本题考查了考生对事实细节的概括能力。文章第二段就理智和启示二者的关系作了详细的论述。该段第一句明确指出，决定经院哲学家持有共同观点最重要的一点是他们确信理智和启示二者间基本的和谐关系。接下来第三句作者提到，二者表面上的对立可以追溯到对理智的错误运用和对启示的误解中，所以［C］项错误。该段后半部分内容中作者对二者的关系进一步展开具体论述：经院哲学家坚信启示能掌握更高层次的真理和确定性；在宗教信仰和哲学推理表面上的冲突中，信仰总是更高层次的裁决者，神学者的决定支配着哲学家的决定。可见［B］项是两者关系的恰当诠释。［A］项和［D］项文中未提及。

第8题：
Which of the following correctly describe the various functions and virtues of a router? (Select all valid answer choices)
A. Packet switching
B. Collision prevention on a LAN segment.
C. Packet filtering
D. Broadcast domain enlargement
E. Broadcast forwarding
F. Internetwork communication
G. None of the above
A,C,F 解析：Explanation:
The main function of a router is to connect different, separated networks together. In doing so, switching packets from one network to another is a primary function, along with providing for communication between networks. As an additional feature, routers are capable of providing filtering on a network address and application port level, so choice C is also correct.
Incorrect Answers:
B. Routers can indeed be used to segment a network separate a collision domain, since routers do not forward LAN broadcasts and multicasts to other interfaces. However, routers alone can not prevent all collisions from occurring on any given LAN segment.
D. Routers actually segment LANs into smaller broadcast domains.
E. Routers do not forward broadcast and multicast traffic out the additional interfaces by default. Unless bridging or IP helpers are configured on the router, LAN broadcasts are blocked at the router level.
