【名词&注释】
成活率(survival rate)、网络安全(network security)、防火墙、狂犬病(rabies)、网络连接(network connection)、国家公园、行政人员(administrative staff)、严重危害(serious harm)、木马程序(trojan horse program)、有效地(effectively)
[单选题]国家公园里没有灰狼出没已经好几十年了，管理公园的行政人员(administrative staff)希望在不危害公园现存其他野生物种生存情况下重建灰狼种群。因为，在公园里灰狼有足够的猎物充食，灰狼也避免和人近距离地接触。因此重新引进灰狼可以在不严重危害(serious harm)游客安全的情况下实现公园行政人员(administrative staff)的目标。如果下面每项内容为真，除了哪一项之外都加强上文的推理?
A. 公园如此之大以致于灰狼毋须冒险进入人类经常光顾的区域。
B. 灰狼患狂犬病是很罕见的，人类受没有患狂犬病的灰狼严重伤害的可核实案例自有记录以来还没有一例出现。
C. 公园附近的农场主已经担心一旦重新引进灰狼，灰狼有时候会把他们的家畜作为猎物捕食。
D. 灰狼对公园里弱小、缺乏营养狒狒的捕食很可能对提高狒狒种群的总体健康和成活率有益。
E. 灰狼不会捕食公园里现存的任何快要灭绝的物种。

[单选题]Prior to the UML, there was no clear leading(111)language. Users had to choose from among many similar modeling languages with minor differences in overall(112)power. Most of the modeling languages shared a set of commonly accepted concepts that are expressed slightly differently in various languages. This lack of(113)discouraged new users from entering the OO market and from doing OO modeling, without greatly expanding the power of modeling. Users longed for the industry to adopt one, or a very few, broadly supported modeling languages suitable for(114)usage.Some vendors were discouraged from entering the OO modeling area because of the need to support many similar, but slightly different, modeling languages. In particular, the supply of add-on tools has been depressed because small vendors cannot afford to support many different formats from many different(115) modeling tools. It is important to the entire O0 industry to encourage broadly based tools and vendors, as well as niche products that cater to the needs of specialized groups.
