这是第二段
Since around 50 percent of all stars are believed to
begin their lives with masses greater than 1.4M⊙, we
might expect that one out of every two stars would die as
a supernova. But in fact, only one star in thirty dies such a
violent death. The rest expire much more peacefully as
planetary nebulas. Apparently most massive stars manage
to lose sufficient material that their masses drop below
the critical value of 1.4 M⊙  before they exhaust their
nuclear fuel. Evidence supporting this view comes from
observations of IRC+10216, a pulsating giant star located
700 light-years away from Earth. A huge rate of mass loss
(1 M⊙  every 10,000 years) has been deduced from  
infrared observations of ammonia (NH3) molecules
located in the circumstellar cloud around IRC+10216.  


这是问题:
3. The view mentioned in the middle of the second
paragraph serves to  
   (A) reconcile seemingly contradictory facts
  (B) undermine a previously held theory
  (C) take into account data previously held to be
 insignificant
  (D) resolve a controversy
  (E) question new methods of gathering data



我选的B,答案是A,求解!

这里 我觉得,不能使完全地否定之前的结论,毕竟还是有恒星会变成超新星,只是没以前预测的多,而这里恰好给出没有预测的多的一个解释
