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
