问题     Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn’t know for sure? That the evidence was inconclusive, the science uncertain? That the antismoking lobby was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves.
    There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming.The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth’s atmosphere is definitely warming and that the problem is largely man-made.The clear message is that we should get moving to protect ourselves.The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel’s report: "Science never has all the answer.But science does provide us with the best available guide to the future, and it is critical that our nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions."
    Just as on smoking, voice now come from many quarters insisting that the science about global warming is incomplete; that it’s OK to keep pouring fumes into the air until we know for sure.This is a dangerous game: by the time 100 percent of the evidence is in, it may be too late.With the risks obvious and growing, a prudent people would take out an insurance policy now.
    Fortunately, the White House is starting to pay attention.But it’s obvious that a majority of the president’s advisers still don’t take global warming seriously.They continue to press for more research, a classic of "paralysis by analysis".
    To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research.But research alone is inadequate.If the Administration won’t take the legislative initiative, Congress should help to begin fashioning conservation measures.A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial incentives for private industry, is a promising start.Many see that the country is getting ready to build lots of new power plants to meet our energy needs.If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.
An argument made by supporters of smoking was that______.
选项 A、there was no scientific evidence of the correlation between smoking and death
B、the number of early deaths of smokers in the past decades was insignificant
C、people had the freedom to choose their own way of life
D、antismoking people were usually talking nonsense
答案C
解析 本题可参照文章的第l段：还记得以前的那些岁月吗?当时，科学家认为吸烟会使我们丧命，而怀疑者则坚持认为我们不能肯定这种观点。反对吸烟的游说团体就要破坏我们的生活方式了，政府应该袖手旁观吗?据此可知，支持吸烟者认为，人们有权选择他们自己的生活方式。C项与文章的意思相符。因此C项为正确答案。
