问题     When people talk about a "north-south divide" in Britain, they usually refer to house prices, employment and the ratio of private-sector to public-sector jobs. The south scores higher on all such measures. But new data from the British Trust for Ornithology (BTO), a research charity, implies the growth of another north-south divide—this time to the north’s benefit.
    Every 20 years the BTO produces a detailed picture of bird life in Britain and Ireland. The 2007 to 2011 edition is cheery: more species are recorded than in previous pictures, and many birds are increasing in number. Compared with two decades ago, 45% of regular native species are ranging more widely while 32% are living in smaller areas; the rest have stayed put. But the most striking news comes from the north.
    The overall populations of woodland, farmland and migrant perching birds are up in northern England and Scotland but down in the south. The same is true of individual species such as the garden warbler, bullfinch and swallow. The number of cuckoos, a closely-watched species, declined by 63% in England between 1995 and 2010 but by only 5% in Scotland. Raptors are faring especially well in the south, but their numbers are rising in most parts of Britain.
    Partly this reflects climate change, suggests Simon Gillings of the BTO. Some birds are drawn to warmer winters in Scotland and northern England; visiting migrants may stick around for longer. Hard though it may be to believe during a week of rain, the south is becoming drier, pushing snipe northward. More efficient farming has squeezed some farmland species.
    Some birds find it harder to make homes in the south, too. Pressure on housing means deserted buildings and barns, handy for nesting, have been converted into human dwellings. Between 2006 and 2012 the number of vacant dwellings fell by 17% in London and by 12% in Kent. Over the same period the number of empty houses increased by 16% in Derbyshire and by 10% in Lancashire. Northern mining villages once full of workers are now sparsely populated, points out Ian Bartlett, a birdwatcher in Hartlepool, in north-east England. They have become hot spots for birds and the people who watch them.
    Cultural difference also plays a part, thinks Mark Cocker, an expert on birds. The "obsession with tidiness" is stronger in the south, he says. Fewer people cultivate gardens; they prefer to cover them in decking and remove weeds from between concrete slabs. Village greens are mowed short. In contrast, Scotland and northern England have more trees, grassland and wind-swept moors. Less popular with humans, rugged parts of the countryside are filling up with a winged population instead.
What can be learned from the last paragraph?

选项 A、Culture elements are decisive according to experts on birds.
B、The role played by different cultures is obvious according to Mark Cocker.
C、Northerners care more about tidiness than southerners.
D、Southerners care only about tidiness when it comes to housing style.

答案B

解析 选项A夸大了文化因素的作用,最后一段首句仅仅表明“cultural difference also plays a part”,并非“decisive(决定性的)”。选项C是对最后一段中“The‘obsession with tidiness’is stronger in the south”的相反表达,而选项D中only一词夸大了南方人对tidiness的关注,而且该段并没有涉及到太多的housing style。选项B符合第一句以及该段全段内容。最后一段讲述南北方因为文化不同而使得村庄、花园等风貌有差异,这正是马克·科克尔的观点。故选项B正确。
