问题     Fate has not been kind to the western grey whale. Its numbers have dwindled to 130 or so, leaving it "critically endangered" in the eyes of the International Union for the Conservation of Nature. Fishing-nets, speeding ships, pollution and coastal development threaten the few that remain. Most recently, drilling for oil and gas in their main summer feeding grounds, near Sakhalin island off Russia’s Pacific coast, has brought fresh risks for the luckless creatures. Yet the rush to develop Sakhalin’s offshore fields may yet be the saviour of the species.
    When drilling was first discussed in the 1990s, there were muted complaints. When a consortium called Sakhalin Energy, led by Royal Dutch Shell, announced plans to build an oil platform and lay pipelines in the only bay where the whales were known to congregate, these protests proliferated.
    In response, the consortium established an independent panel to advise it on how best to protect the whales and promised to fund its work. It subsequently agreed to change the route of the pipeline at the panel’s suggestion, although it refused to move the platform, as other critics had demanded. It also agreed either to follow the panel’s recommendations in future or to explain publicly why it was rejecting them.
    The platforms and pipelines are now complete. Sakhalin Energy exported its first cargo of liquefied natural gas last week. The project, says Shell, is an engineering triumph and a commercial success despite all the controversy.
    But has it been a success for the whales? Sakhalin Energy says their number seems to be growing by 2. 5% a year, although Ian Craig, the firm’s boss, admits that the cause might be greater scrutiny rather than population growth. The scientists on the panel still seem worried. They complain that the firm has not always provided the information they need to assess the threat to the whales. It also has not always followed advice, the scientists’ advice about how noisy construction might scare the animals away, for example, or the speed that boats should travel to minimize the risk of hitting the whales. The scientists warn that the loss of just a few fertile females would be enough to tip the population into irrevocable decline. Last summer, there seemed to be far fewer whales around than normal.
    On the other hand, the panel knows this only because Sakhalin Energy funds lots of research on the whales. As a result, it has discovered that they have a wider range than originally thought, which might explain why so few of them showed up off Sakhalin island last year.
    Therefore, it is hard to escape the conclusion that, for creatures with a lot as sorry as the western grey whale, a nearby oil project is something of a blessing.
Why are Sakhalin’s offshore oil and gas projects regarded as risks for the western grey whale?
选项 A、Because they instantly endanger the animal’s summer habitat.
B、Because drilling for oil and gas may cause new pollution to the sea.
C、Because they need more ships which are dangerous to the animal.
D、Because offshore development may result in more harm.
答案A
解析 推理判断题。由题干关键词将信息定位于第一段倒数第二句。该句谈到，在灰鲸夏季主要觅食地进行的石油和天然气的开采为灰鲸带来了新的危险；由此推断，危险的原因是石油和天然气工程会直接威胁到灰鲸夏季的栖息地，故[A]正确，habitat是原文feeding grounds的同义转述。[B]、[C]、[D]可能是潜在的危险，但仅是推测．在原文中找不到充分的依据，所以不是本题答案。
