下面的材料对开平碉楼作了介绍。请根据此段文字内容,为碉楼拟一则宣传语,向游客推介。至少使用一种修辞手法。
在开平市内,碉楼星罗棋布,城镇农村,举目皆是,纵横数十公里连绵不断,蔚为大观。这一座座碉楼,是开平政治、经济和文化发展的见证。开平碉楼的兴起,与开平的地理环境和过去的社会治安密切相关。开平地势低洼,河网密布,而过去水利失修,每遇台风暴雨,常有洪涝之忧。加之历史上开平一带社会秩序较为混乱,因此,清初即有乡民建筑碉楼,作为防涝防匪之用。开平作为华侨之乡、建筑之乡和艺术之乡,它的特色在碉楼上都得到了鲜明的体现。开平碉楼是中国乡土建筑的一个特殊类型,是一种集防卫、居住和中西建筑艺术于一体的多层塔楼式建筑。碉楼是中国乡村民众主动接受西方建筑艺术,并将之与本土建筑艺术融合的产物,是活生生的近代建筑博物馆,让人叹为观止。开平碉楼现正申报世界文化遗产。

One of the most widely used routing protocols in IP networks is the Routing Information Protocol(RIP).RIP is the canonical example of a routing protocol built on the (71) algorithm.Routing protocols in internetworks differ slightly from the idealized graph model.In aninternetwork,the goal of the routers to forward packets to various (72) . Routers running RIP send their advertisement about cost every (73) seconds.A router also sends an update message whenever an update from another router causes it to change itsrouting table. It is possible to use a range of different metrics or costs for the links in a routing protocol.RIP takes the simplest approach,with all link costs being equal (74) Thus it always tries tofind the minimum hop route.Valid distances are 1 through (75) .This also limits RIP torunning on fairly small networks.
A.1 B.15 C.16 D.length of the link
