引用外文网的一个解释:
“For a weakening question, we want to cast doubt on the author's conclusion.
The author concludes that the environmentalists are wrong, i.e. that the number of turtles will decline as a result of the spill is incorrect. The author bases this on the number of females who returned this year, 5 years after the spill, is higher than previous years.
One great way to weaken is to show that the author's evidence is irrelevant to the author's conclusion. Choice (B) does exactly that.
If it takes 10 years for turtles to mature to egg laying status, then looking at numbers only 5 years after the spill is irrelevant. Since (B) renders the author's evidence irrelevant, it weakens the author's conclusion.”----http://www.beatthegmat.com/turtle-t28611.html
